ASML Elephant High NA EUV

Contrary to the popular press, ASML High-NA EUV is not ready for logic production yet—and it may never be, at least not in the form originally envisioned. If you remember how long it took conventional EUV to become production-worthy—arguably 5–10 years—this should not come as a surprise. More importantly, this is no longer just a technical decision. It is now a value proposition decision.

As things stand today, the answer appears to be no: the benefits of High-NA EUV do not justify the cost and risk at 1.4nm.

One of the biggest industry shifts is that foundry customers now have a voice in process technology decisions, and you can thank TSMC for that. TSMC’s collaborative business model gives major customers direct input on manufacturing roadmaps. The top TSMC customers I have spoken with are not ready to embrace High-NA EUV given the current economics and manufacturing risks.

TSMC has said as much publicly during the last two Technology Symposiums. In briefings at both the 2025 Symposium and last month’s event, Dr. Kevin Zhang, Senior Vice President and Deputy Co-COO, made it clear that High-NA EUV is simply too expensive relative to the expected benefit.

Intel had planned to introduce High-NA EUV at the 14A node under former CEO Pat Gelsinger. That was a classic IDM-style decision made largely without customer feedback. Under Lip-Bu Tan, however, customers are expected to have far greater influence over technology choices—which likely means Intel will move closer to the TSMC customer-first model. Samsung may not have much choice either. Foundry customers have spoken.

To be clear, ASML’s High-NA EUV technology works. The question is not technical feasibility. The real question is whether it can achieve the yield, uptime, and economics required for profitable high-volume manufacturing.

The core technical challenge is that High-NA EUV dramatically reduces process margins. Standard EUV tools operate at a numerical aperture (NA) of 0.33, while High-NA increases this to 0.55. The higher NA improves resolution and enables smaller transistor features, but it also significantly reduces depth of focus. In practical terms, wafers must remain almost perfectly flat during exposure. Even tiny variations in wafer topography, thermal distortion, or vibration can create pattern defects that reduce yield.

Photoresists are another major obstacle. High-NA systems require thinner resist films because thicker films exceed the narrow focus window. However, thinner resists absorb fewer EUV photons, increasing stochastic defects such as broken lines, missing holes, and edge roughness. These defects occur randomly and are extremely difficult to eliminate through standard process optimization. At advanced nodes, even a very small number of stochastic defects can make chips unusable.

EUV also faces a fundamental photon problem. Unlike deep ultraviolet lithography, EUV operates with relatively low photon counts. At High-NA dimensions, statistical fluctuations in photon absorption become significant enough to impact pattern fidelity. Electron blur following photon absorption further reduces precision. As the industry approaches the angstrom era, these random physical effects become increasingly difficult to control.

Mask technology introduces another layer of complexity. High-NA EUV uses anamorphic optics, meaning image scaling differs between horizontal and vertical directions. This requires entirely new mask architectures and correction algorithms. EUV masks are already among the most complex manufactured objects in the semiconductor industry, and High-NA masks push defect tolerances even further. Some defects are only visible under EUV illumination, making inspection extraordinarily difficult.

Pellicles remain another unresolved issue. These thin protective membranes shield masks from contamination, but High-NA systems require much higher source power levels, creating severe thermal stress. Existing pellicle materials can warp or degrade under sustained exposure. New materials are under development, but they are not yet fully qualified for continuous high-volume manufacturing.

Throughput and uptime are equally critical. Semiconductor fabs depend on extremely high utilization rates because downtime directly impacts profitability. High-NA tools are still early-generation systems and have not demonstrated the long-term reliability of mature EUV platforms. Even relatively small interruptions can create major economic consequences in leading-edge fabs operating 24/7.

Cost may ultimately be the largest barrier of all. Each High-NA EUV scanner costs approximately $350 million to $400 million, making it the most expensive manufacturing tool ever built. Beyond the scanner itself, fabs require major infrastructure upgrades involving power delivery, cooling, vibration isolation, and cleanroom redesign. The total investment required for High-NA production is enormous, and foundries must determine whether the incremental scaling benefits justify the expense.

TSMC appears to have already made that calculation. Rather than rushing into High-NA deployment, the company is extending existing 0.33 NA EUV systems through multipatterning and process optimization. That decision reflects concerns not only about technical maturity, but also about economic return.

The broader ecosystem is another issue. Lithography does not operate in isolation. Etch, deposition, metrology, inspection, design software, packaging, and yield-learning infrastructure must all evolve together. High-NA EUV introduces new interactions throughout the manufacturing flow, meaning the entire semiconductor ecosystem must mature before stable high-volume yields become realistic.

Bottom line: High-NA EUV is stuck in the difficult transition between laboratory success and industrial maturity. The technology has clearly demonstrated capability in research environments and pilot production, but successful semiconductor manufacturing requires much more than technical proof points. Yield stability, uptime, defect reduction, ecosystem readiness, infrastructure investment, and economic viability must all improve before High-NA EUV can become mainstream production technology.

SIemens EDA TSMC Teshnical Symposium 2026

At the recent TSMC Technology Symposium 2026, Siemens EDA reinforced its position as one of the key ecosystem partners supporting TSMC in the race toward AI-driven semiconductor design, advanced packaging, and next-generation process technologies. The annual forum has become one of the semiconductor industry’s most important gatherings, bringing together foundry customers, EDA suppliers, IP vendors, and packaging innovators to align around future technology nodes and design methodologies.

A major theme throughout the event was the growing impact of artificial intelligence on chip development. Siemens EDA used the symposium to highlight expanded collaboration with TSMC focused on AI-powered automation across the semiconductor workflow. The companies announced joint work involving automated Design Rule Check fixing, AI-assisted physical verification, and intelligent design optimization using Siemens’ recently introduced Fuse EDA AI System.

The partnership reflects a broader industry shift. Semiconductor complexity is increasing dramatically as AI accelerators, high-performance computing devices, automotive processors, and chiplet-based architectures push beyond the limits of traditional design methods. Designers are now managing multi-die systems, advanced 3D packaging, massive data throughput requirements, and power delivery challenges simultaneously. As a result, AI-enabled EDA tools are becoming critical to reducing development cycles and improving productivity.

Siemens emphasized that its AI technologies are being integrated directly into production-proven tools such as Calibre and Aprisa. According to the company, TSMC is collaborating with Siemens to improve multi-step automation for DRC-centric physical verification while also helping engineers gain faster access to design insights and guided recommendations during implementation.

One of the most significant aspects of the announcement involved support for TSMC’s latest process technologies. Siemens reported certifications for its EDA tools on multiple advanced nodes including N3A, N3C, N2P, A16, and A14 technologies. These certifications are essential because semiconductor companies require validated design flows before committing billions of dollars to advanced-node tape-outs. By securing early enablement and certification, Siemens ensures that mutual customers can begin development with confidence on TSMC’s newest manufacturing platforms.

Another important focus at the forum was advanced packaging and 3D integration. TSMC continues expanding its 3DFabric and CoWoS packaging ecosystems to support increasingly complex AI systems. Siemens highlighted capabilities within its Calibre 3DStack platform that address interface checking, connectivity verification, inter-chiplet DRC validation, antenna analysis, and current density analysis for 3D systems. These capabilities are particularly important as AI processors move toward heterogeneous integration involving logic, memory, photonics, and specialized accelerators inside a single package.

Industry analysts noted that the symposium showcased an increasingly competitive environment among the three leading EDA vendors: Siemens, Synopsys, and Cadence. While all three announced expanded TSMC collaborations, Siemens differentiated itself through its emphasis on agentic AI orchestration and design-to-manufacturing integration. The company’s strategy appears centered on automating complex workflows that traditionally require extensive engineering intervention.

The timing of these announcements is significant. TSMC’s roadmap now includes multiple sub-2nm technologies, backside power delivery, advanced automotive nodes, and co-packaged optics initiatives. Each of these innovations introduces new design and verification challenges. Semiconductor companies are under intense pressure to reduce design turnaround time while maintaining power, performance, and reliability targets. AI-assisted automation is increasingly viewed as the only viable way to sustain productivity improvements at advanced nodes.

At the symposium, TSMC also reinforced the importance of its Open Innovation Platform (OIP) ecosystem, where Siemens remains a key partner. The OIP model enables close collaboration between foundry technologies and EDA tool providers, ensuring early process enablement and optimized design flows. Siemens’ long-standing participation in this ecosystem has allowed it to remain deeply integrated into TSMC’s technology roadmap.

The broader semiconductor industry context also shaped discussions at the event. According to industry commentary surrounding the symposium, AI demand is driving unprecedented semiconductor growth, especially in high-performance computing infrastructure. Advanced packaging capacity, power delivery innovation, and chiplet architectures are becoming central to competitive differentiation. As these challenges intensify, EDA vendors are evolving from traditional software providers into strategic enablers of AI-era semiconductor development.

For Siemens EDA, the TSMC Technical Forum served as more than a technology showcase. It was a strategic statement about the future direction of chip design. The company is positioning itself at the intersection of AI automation, advanced manufacturing enablement, and heterogeneous system integration. By strengthening collaboration with TSMC, Siemens aims to help semiconductor companies accelerate innovation while managing the escalating complexity of next-generation designs.

Bottom line: As AI continues reshaping the semiconductor industry, partnerships like Siemens and TSMC will likely become even more important. Future chip development will depend not only on transistor scaling, but also on intelligent automation, advanced packaging methodologies, and tightly integrated ecosystem collaboration. The announcements made at the TSMC Technical Forum suggest that Siemens EDA intends to play a central role in enabling that future.

imec IC-Link and TSMC 3DFabric Alliance Expansion Signals New Era of System-Level Scaling

imec IC-Link and TSMC 3DFabric Alliance Expansion Signals New Era of System-Level Scaling

TSMC 3DFabric Alliance Expansion Signals New Era of System Level Scaling

imec announced that IC-Link by imec has joined the TSMC 3DFabric Alliance, a strategically important move that reflects the semiconductor industry’s transition from traditional monolithic scaling toward heterogeneous integration, chiplet architectures, and advanced packaging-driven system optimization. The partnership is technically significant because it combines imec’s globally respected research expertise in advanced packaging and system scaling with TSMC’s production-leading 2.5D and 3D integration ecosystem, enabling faster commercialization of next-generation AI, HPC, automotive, and mobile semiconductor solutions.

For decades, semiconductor innovation was driven primarily by transistor scaling under Moore’s Law. Smaller transistors delivered higher performance, lower power, and lower cost per function. However, as process technologies approach physical and economic scaling limits below 3nm, system-level innovation has become equally important. Today, the bottleneck in many AI and HPC systems is no longer only compute density, but memory bandwidth, interconnect latency, thermal management, and power delivery. Advanced packaging technologies such as chiplets, 2.5D interposers, wafer-level integration, and 3D die stacking are increasingly becoming the primary mechanism for improving overall system performance.

TSMC’s 3DFabric platform addresses these challenges through a portfolio of advanced integration technologies that includes TSMC-SoIC®, CoWoS®, InFO, and TSMC-SoW™. These technologies enable heterogeneous integration, allowing logic, memory, analog, photonics, and specialized accelerators to be integrated into a unified package. Instead of building one extremely large monolithic die, designers can partition functionality across multiple optimized chiplets fabricated on different process nodes and interconnected with ultra-high bandwidth packaging technologies. This approach improves yield, reduces development cost, accelerates design reuse, and enables greater scalability for AI infrastructure.

The addition of IC-Link to the 3DFabric Alliance is important because IC-Link functions as a bridge between semiconductor research and industrial manufacturing. Imec already possesses deep expertise in heterogeneous integration, silicon photonics, advanced packaging, and ASIC development. Through IC-Link, these research capabilities can now be directly connected to TSMC’s production ecosystem. This reduces the traditional gap between R&D innovation and manufacturable commercial products.

One of the most critical technical implications is co-optimization between silicon design and packaging. In advanced AI systems, packaging is no longer treated as a backend assembly step. Instead, package architecture must be designed simultaneously with silicon architecture. Thermal dissipation, power delivery networks, interconnect topology, and memory placement all influence final system performance. The 3DFabric Alliance enables ecosystem participants to collaborate earlier in the design cycle, which improves design convergence and shortens time-to-market for complex multi-die systems.

This collaboration is particularly relevant for AI and HPC applications. Large language models and AI inference engines require enormous memory bandwidth and low-latency interconnects between compute and memory resources. Traditional package architectures cannot efficiently support these requirements. Technologies like CoWoS and SoIC enable high-density die-to-die interconnects and vertically stacked memory integration, significantly increasing bandwidth while reducing power consumption per bit transferred. This packaging-centric architecture is now central to competitive AI accelerator design.

Another major technical advantage is access to advanced manufacturing readiness. Through the alliance, IC-Link customers gain earlier access to TSMC’s advanced packaging flows and validated ecosystem infrastructure. This includes design enablement, IP integration, packaging qualification, substrate technologies, and manufacturing interoperability. For fabless semiconductor companies, especially startups and European innovators, this reduces development risk and accelerates the path from prototype to high-volume production.

The announcement also reflects the growing importance of Europe in advanced semiconductor development. Europe has historically been strong in semiconductor equipment, automotive electronics, and research, but less dominant in leading-edge manufacturing ecosystems. Imec has emerged as one of the world’s most influential semiconductor R&D organizations, and this partnership strengthens Europe’s role in advanced packaging innovation. By integrating with TSMC’s global ecosystem, imec can help European companies access state-of-the-art 3D IC technologies without building independent manufacturing infrastructure from scratch.

From a system architecture perspective, the industry is rapidly moving toward modular semiconductor design. Chiplet-based systems allow designers to independently optimize compute, I/O, memory, RF, and photonics functions using different process technologies. This modularity improves flexibility and lowers development cost while enabling rapid innovation cycles. However, chiplet integration introduces major complexity in interconnect density, signal integrity, thermal coupling, and package reliability. Ecosystem collaboration therefore becomes essential. The 3DFabric Alliance was specifically created to solve these integration challenges through cross-industry collaboration between foundries, packaging providers, EDA vendors, IP suppliers, and manufacturing partners.

The timing of the announcement is also important. Demand for advanced packaging capacity has surged because of AI infrastructure growth. Packaging technologies such as CoWoS have become strategic industry bottlenecks. Semiconductor companies increasingly compete not only on transistor technology, but on the ability to integrate large-scale AI systems efficiently. By joining the alliance now, IC-Link positions itself to support the next wave of AI accelerator development and heterogeneous system integration.

Bottom line: IC-Link joining the TSMC 3DFabric Alliance represents more than a business partnership. It signals a broader industry transformation in which advanced packaging and 3D integration are becoming primary drivers of semiconductor innovation. The collaboration combines imec’s research leadership with TSMC’s manufacturing scale to accelerate the development of complex multi-die systems optimized for AI, HPC, automotive, and next-generation communications. As semiconductor scaling becomes increasingly system-centric, alliances like this will define the future competitive landscape of the semiconductor industry.

TSMC’s Record Tool Orders Hint at Another CapEx Shockwave

TSMC’s Record Tool Orders Hint at Another CapEx Shockwave 2026

TSMC’s latest Board of Directors capital appropriation announcement may appear mixed on the surface, but a closer look reveals one important conclusion: The company is quietly setting the stage for another potential upward revision to its already aggressive 2026 capital expenditure outlook. The headline figure of $31.3B in newly approved capital appropriations was below the massive $45.0B approved in the prior quarter, yet the composition of this spending tells a much more constructive story for the semiconductor equipment ecosystem.

The most notable development is the continued acceleration in Advanced Node equipment investment. TSMC approved approximately $21.0B of Advanced Node-related equipment spending this quarter, representing the highest quarterly authorization level since we began tracking the company’s BoD capital approvals in 4Q19. Even though total approved spending declined sequentially, the shift toward leading-edge wafer fabrication equipment indicates that TSMC’s strategic focus remains firmly centered on expanding advanced logic capacity.

This distinction matters. Infrastructure spending and specialty technology investments can fluctuate depending on timing, construction schedules, or packaging initiatives. Advanced Node equipment approvals, however, are a far cleaner signal of future semiconductor manufacturing activity. They directly correlate with purchases of lithography, process control, deposition, etch, and metrology systems required for ramping leading-edge nodes such as N2 and A16.

At the same time, there was a notable absence of new approvals for Specialty Devices and Advanced Packaging. Last quarter’s record approval in this category was later understood to be tied to silicon photonics, CoWoS, and SoIC-related investments. The lack of follow-on approvals this quarter should not necessarily be interpreted as weakening demand. Rather, it likely reflects the exceptionally large allocation already approved previously. Given the long lead times and substantial scale of advanced packaging infrastructure deployment, TSMC may simply be digesting prior commitments before authorizing another major tranche of spending.

Infrastructure spending also normalized this quarter. The $10.3B approval level was meaningfully lower than the record $21.4B authorized in the prior quarter. However, this moderation appears more cyclical than structural. Infrastructure allocations often fluctuate depending on the timing of fab shell construction, utility expansion, overseas manufacturing projects, and regional government incentives. The key takeaway is that infrastructure moderation did not come alongside any slowdown in Advanced Node investment intensity.

Perhaps the most important data point from this quarter is the emerging disconnect between approved future spending and TSMC’s current annual CapEx guidance. Assuming BoD capital appropriations generally represent roughly the next 12 months of spending activity, the trailing twelve-month Advanced Node equipment authorization level has now climbed to approximately $55.0B. That figure alone nearly matches TSMC’s entire current 2026 capital expenditure guidance of roughly $56B.

This creates an increasingly difficult mathematical setup. If Advanced Node equipment alone already represents nearly the full-year CapEx plan, then either spending cadence must slow materially in coming quarters or total CapEx guidance will need to move higher. Given current AI infrastructure demand trends, slowing investment appears unlikely.

The broader industry backdrop strongly supports the latter scenario. AI-driven compute demand continues to accelerate across hyperscale data centers, sovereign AI projects, enterprise deployments, and edge inference applications. Leading-edge silicon demand remains supply constrained, particularly for advanced GPUs, AI accelerators, networking ASICs, and high-bandwidth memory integration. TSMC remains the dominant manufacturing partner for virtually all major AI chip developers, placing extraordinary pressure on its advanced manufacturing capacity roadmap.

As a result, TSMC’s quarterly CapEx run rate likely needs to increase further over the next twelve months. The company’s N2 ramp, advanced packaging expansion, overseas fab deployment, and ongoing EUV intensity growth all point toward sustained elevated investment levels. This is why the probability of a 2026 CapEx raise at TSMC’s 2Q26 earnings conference call in July appears to be increasing.

Bottom line: The latest TSMC approval data reinforces a critical industry theme: despite periodic fluctuations in quarterly headline numbers, leading-edge semiconductor investment remains in a structural expansion phase. AI demand is fundamentally altering semiconductor infrastructure requirements, and TSMC’s capital allocation patterns continue to reflect that reality. In fact, the latest BoD approvals may ultimately be remembered less for the sequential decline in total authorizations and more as an early signal that TSMC’s current 2026 CapEx framework is already becoming too conservative.

Synopsys and TSMC Deepen AI Design Alliance: What It Means

Synopsys and TSMC Deepen AI Design Alliance: What It Means

Synopsys Powering the next generation of AI

A recent announcement from Synopsys signals a meaningful escalation in the race to build next-generation AI hardware. The expanded collaboration between Synopsys and TSMC brings together silicon-proven IP, AI-driven design tools, and cutting-edge manufacturing processes in a tightly integrated effort to accelerate high-performance computing (HPC) and AI system development. More than a routine partnership update, the move reflects a broader industry transition toward ecosystem-level innovation, where success depends on how well design, IP, and fabrication technologies align from the outset.

What Was Announced

At the core of the announcement is a three-part expansion of capabilities spanning IP, design flows, and system-level enablement.

Synopsys is advancing silicon-proven interface IP validated on TSMC’s most advanced nodes, including 3nm and emerging 2nm-class processes. These include next-generation standards such as M-PHY v6.0 which is now achieving industry-first low-power silicon bring-up on N2P, alongside tapeouts of 64G UCIe IP and 224G high-speed interconnect IP. Together, these technologies form the backbone of AI chips that must move massive volumes of data with minimal latency and power overhead, particularly in bandwidth-constrained environments.

The companies are also extending certified electronic design automation (EDA) flows with a sharper emphasis on increasingly agentic AI-driven optimization. Collaboration on run assistance within Synopsys Fusion Compiler, leveraging TSMC’s A14 process and NanoFlex Pro architecture, is aimed at improving power, performance, and area (PPA) while boosting design productivity. This signals a shift from passive AI assistance toward more active, decision-guiding systems that can materially impact how chips are designed at advanced nodes.

Beyond individual dies, the partnership continues to push into advanced packaging and system-level integration. Synopsys’ 3DIC Compiler platform is now enabling productivity improvements for TSMC’s CoWoS technology at interposer sizes reaching up to 5.5 times the reticle limit, underscoring the scale of modern multi-die designs. This is complemented by multiphysics simulation capabilities that address thermal, electrical, and optical interactions. These requirements are becoming essential as chips evolve into tightly integrated systems.

The announcement also highlights expansion into new application domains. In automotive, Synopsys is offering a UCIe IP solution compliant with ASIL B functional safety requirements on TSMC’s N5A process, marking a significant step toward enabling chiplet-based architectures in safety-critical environments. Meanwhile, advancements in M-PHY IP are targeted at next-generation mobile and storage applications, including smartphones that demand both high performance and power efficiency.

Finally, the collaboration advances AI infrastructure through co-packaged optics. Multiphysics design enablement for co-packaged optical systems, including TSMC’s COUPE design flow, spans optical path simulation, electromagnetic extraction, and system-level analysis, and is paired with 224G IP designed to support optical Ethernet and emerging interconnect standards such as UALink. Together, these capabilities directly address the growing bandwidth and energy challenges facing large-scale AI systems.

Why This Matters for AI Hardware

The significance of this partnership lies in how it tackles the core constraints of modern AI workloads. As compute performance scales, the bottlenecks have shifted toward data movement, power efficiency, and system integration. By combining high-speed IP, agentic AI-driven design tools, and advanced packaging technologies, Synopsys and TSMC are reducing the gap between design complexity and manufacturable silicon.

The introduction of agentic run assistance in EDA tools marks a particularly important inflection point. Rather than simply accelerating existing workflows, these capabilities begin to reshape them, enabling engineers to delegate increasingly complex optimization tasks to AI systems. This has the potential to significantly compress development cycles while improving overall design quality.

Equally critical is the focus on bandwidth. Technologies such as 224G interconnects and co-packaged optics are emerging as key enablers for scaling AI infrastructure, where moving data efficiently is often more challenging than processing it. By integrating these capabilities into both IP and design flows, the partnership addresses one of the most pressing limitations in next-generation AI systems.

The expansion into automotive and mobile markets further underscores the breadth of this strategy. It signals that advanced-node, multi-die, and chiplet-based designs are no longer confined to hyperscale data centers but are beginning to permeate safety-critical and consumer applications as well.

Market And Industry Implications

The expanded alliance reinforces Synopsys’s position as a central player in AI silicon enablement while strengthening TSMC’s ecosystem around its most advanced process nodes. For chip designers, tighter integration between EDA tools and foundry technologies can translate into faster time-to-market and reduced development risk, particularly when targeting cutting-edge nodes.

At the same time, the partnership reflects a broader industry dynamic in which design tools and manufacturing processes are becoming increasingly interdependent. As flows become more deeply optimized and certified for specific nodes, the cost and complexity of switching ecosystems rise. This creates a form of strategic lock-in that benefits tightly aligned partners while raising barriers for competitors.

The Bigger Picture

Taken together, the announcement illustrates a shift in how semiconductor innovation is defined in the AI era. Progress is no longer driven solely by transistor scaling but by the ability to coordinate across multiple layers of the technology stack, from design software and reusable IP to packaging and system integration.

The Synopsys–TSMC collaboration points to a future where chips are conceived not as isolated components but as parts of larger, highly integrated systems spanning data centers, vehicles, and mobile devices. In this landscape, competitive advantage will increasingly depend on how effectively companies can bring together tools, technologies, and partners to deliver complete, optimized solutions.

As AI continues to push the limits of performance and complexity, partnerships like this are likely to define the pace of innovation. The companies that succeed will be those that can bridge the gap between design intent and real-world deployment, turning increasingly sophisticated ideas into scalable, manufacturable systems.

L.C. Lu TSMC Senior Fellow and Vice President, Research and Development Design & Technology Platform (1)
Dr. L.C. Lu is Vice President of Research & Development / Design & Technology Platform at Taiwan Semiconductor Manufacturing Co. Ltd. (TSMC) and a TSMC Senior Fellow.

L.C. leads efforts in design enablement, ensuring that the company can meet the diverse and evolving requirements of its global customer base. Prior to this, he headed the Design and Technology Platform organization starting in 2018.

Since joining TSMC in 2000, Dr. Lu has held multiple leadership positions in design services. He has worked closely with process R&D teams to pioneer Design and Technology Co-Optimization (DTCO), improving speed, power efficiency, and density in advanced process technologies. He has also collaborated extensively with ecosystem partners through the TSMC Open Innovation Platform (OIP), helping deliver comprehensive design solutions and intellectual property for a wide range of applications, including high-performance computing, automotive, RF, and advanced 2.5D and 3D designs.

Dr. Lu’s contributions have earned him significant recognition. He received Taiwan’s National Outstanding Manager Award in 2012 and was named a TSMC Senior Fellow in 2025. He is also one of the company’s most prolific inventors, holding more than 100 patents worldwide.

He earned his bachelor’s degree in electrical engineering from National Taiwan University, a master’s degree in computer science from National Tsing Hua University, and a Ph.D. in computer science from Yale University.

L.C.’s presentation focuses on advanced design-technology co-optimization (DTCO), packaging innovations, and AI-driven methodologies that enable continued scaling in performance, power, and area (PPA) for next-generation semiconductor systems. The discussion highlights how tightly coupled design and process innovations, along with system-level integration, are critical to sustaining Moore’s Law in the era of AI and HPC.

At the device and design level, TSMC emphasizes DTCO and design-driven cell (DDCL) innovations to achieve node-to-node scaling from N5 through N2 and into A14. The introduction of NanoFlex and NanoFlex Pro architectures enables flexible standard cell design with significant gains in efficiency. N2 NanoFlex achieves up to 50% speed improvement at constant voltage or 50% power reduction at constant performance compared to traditional cells. Building on this, A14 NanoFlex Pro introduces a 1.5× cell height merged oxide diffusion (OD) architecture, significantly improving OD utilization and enabling tighter placement of high-speed and low-power cells. This results in 10–15% speed gains and ~20% area reduction relative to N2, effectively delivering multi-node scaling benefits within a single generation.

https://x.com/SemiAnalysis_/status/2047888356701306916

Further enhancements in N2P and N2U nodes incorporate advanced DTCO and power delivery optimizations. Hybrid dual-rail architectures reduce minimum operating voltage (Vmin) by over 200 mV compared to single-rail designs, achieving approximately 40% energy savings. N2U extends N2P with incremental improvements—3–4% higher performance or 8–10% lower power—while maintaining full compatibility with existing design rules and IP, ensuring smooth adoption for customers.

EDA readiness and AI integration are key enablers of these advanced nodes. TSMC collaborates closely with electronic design automation (EDA) partners to ensure tool readiness and to incorporate AI-enhanced workflows. Agentic AI systems are being deployed across design cycles to optimize block placement, routing, and performance, improving both productivity and design quality. These AI techniques are also applied to analog and RF design, enabling efficient migration across process nodes and accelerating time-to-market.

At the system level, TSMC’s advanced packaging technologies—particularly CoWoS, SoIC, and 3D Fabric—play a central role in enabling AI scaling. CoWoS technology continues to scale reticle size and integration capacity, allowing significant increases in compute density. From 2024 to 2029, the number of transistors in a single CoWoS system is projected to increase by 48×, driven by larger package sizes, increased system-on-chip (SoC) counts, and transition to advanced nodes such as TSMC A14.

Memory bandwidth scaling is similarly aggressive, with high-bandwidth memory (HBM) integration increasing both capacity and throughput. HBM stacks are expected to grow from 8 to 24, while I/O bandwidth per stack doubles and data rates increase significantly, resulting in an overall 34× bandwidth improvement. This scaling is supported by advancements in both DRAM technology and logic-based base dies fabricated on advanced nodes.

Interconnect performance is improved through finer pitch scaling in both 2.5D and 3D integration. In CoWoS, micro-bump pitch reduction enhances bandwidth density and energy efficiency, while in SoIC, scaling to ~4.5 µm bump pitch delivers up to 4× bandwidth density and substantial energy savings. Additionally, silicon photonics integration via CUPE optical engines provides high-speed, low-latency interconnects, achieving 5–10× power efficiency improvements and 10–20× latency reduction compared to traditional electrical links.

Power delivery and thermal management are identified as critical challenges in AI systems due to increasing compute density. TSMC addresses these through advanced capacitance solutions such as metal-insulator-metal (MIM) capacitors and embedded deep trench capacitors (eDDC), achieving over 10× improvements in capacitance density and reducing voltage droop significantly. Thermal optimization techniques—including improved packaging materials, hotspot spreading, and structural enhancements—reduce thermal resistance by up to 40%, ensuring reliable operation under high power conditions.

Bottom line: TSMC is advancing design methodologies through 3D IC design standardization and AI-driven automation. The introduction of “3D Blocks” as a modular design language aims to streamline 3D IC workflows and enhance collaboration across the ecosystem, with ongoing efforts toward IEEE standardization. Combined with generative AI and agent-based design optimization, these innovations promise substantial improvements in productivity and scalability for complex chip-package co-design.

CoWoS Enables AI Compute Scaling

The rapid rise of artificial intelligence is fundamentally reshaping computing architectures. As AI models scale toward trillions of parameters, traditional approaches to performance improvement are no longer sufficient. Instead, the industry is entering a new era where system-level innovation, advanced packaging, and 3D integration are becoming the primary drivers of progress. This shift reflects a broader transition in computing, where performance gains increasingly depend on how well entire systems are designed and integrated, rather than how small individual transistors can become.

The End of One-Dimensional Scaling

AI compute demand is growing at an exponential rate, creating a widening gap between required performance and what conventional silicon scaling can deliver. Bridging this gap requires innovation beyond the chip itself. The most important shift is that AI performance is now determined at the system level rather than purely at the silicon level. Future gains will depend on how effectively compute, memory, interconnect, and power systems are integrated into a cohesive whole. This marks a transition from device-centric optimization to full-stack co-design, extending from transistor technology all the way to data center architecture.

Data Movement Is the New Bottleneck

A critical constraint in modern AI systems is no longer computation, but data movement. Transporting data across chips can consume up to 50 times more energy than moving data within a single chip. At the same time, data transfer can account for the majority of system activity, significantly reducing accelerator utilization due to communication delays. This shift makes interconnect efficiency a central design priority. Improving bandwidth, reducing latency, and minimizing energy per bit are now essential to unlocking overall system performance.

The Memory Wall Is Getting Worse

As AI models continue to scale, memory demands are increasing even faster than compute capabilities. Emerging workloads, such as long-context processing and multimodal AI, are driving exponential growth in both memory capacity and bandwidth requirements. Systems are transitioning from gigabyte-scale memory to terabyte-scale configurations, while also demanding lower latency. However, memory technology is not advancing at the same pace as compute, creating a widening imbalance. Overcoming this “memory wall” is therefore essential for sustaining AI progress, and it is driving rapid innovation in high-bandwidth memory and memory integration strategies.

Power and Thermal Constraints Are Critical

The increase in compute density, particularly with the adoption of 3D stacking technologies, has led to a corresponding rise in power density and heat generation. These factors are quickly becoming limiting constraints for AI system scaling. Without significant advancements in power delivery, energy efficiency, and thermal management, performance gains cannot be sustained. As a result, power and cooling are no longer secondary considerations but have become central to system design and overall performance.

3D Fabric Technologies: The New Foundation

To address these challenges, advanced 3D fabric technologies are emerging as the foundation of next-generation AI systems. These technologies enable the integration of multiple chips and components into highly efficient, high-performance systems. Innovations such as 3D chip stacking allow for dramatically higher interconnect density, reducing both data movement distance and energy consumption. Advanced packaging platforms make it possible to combine logic and memory in close proximity, enabling massive bandwidth and capacity scaling. At the same time, high-bandwidth memory continues to evolve, delivering higher throughput and improved energy efficiency. Together, these advancements position packaging not merely as a supporting technology, but as a primary driver of system performance.

Co-Packaged Optics: Rethinking Interconnects

As electrical interconnects approach their physical limits, co-packaged optics is emerging as a promising solution for high-speed data transfer. By integrating photonics directly with compute hardware, this approach enables significant improvements in both power efficiency and latency. It also provides a scalable path forward for data center networking, where the need for higher bandwidth and lower energy consumption continues to grow. This evolution signals a broader shift toward optical technologies as a key enabler of future AI infrastructure.

System-on-Wafer and Wafer-Scale Integration

Looking further ahead, system integration is advancing toward wafer-scale architectures, where entire systems are built on a single substrate. This approach enables unprecedented levels of integration density while reducing the overhead associated with traditional interconnects. By minimizing communication distances and improving efficiency, wafer-scale integration offers a powerful pathway for scaling AI performance beyond the limits of conventional packaging methods.

The Rise of System Technology Co-Optimization (STCO)

As AI systems grow more complex, optimizing individual components in isolation is no longer sufficient. The industry is increasingly adopting System Technology Co-Optimization, an approach that simultaneously considers chip design, packaging, interconnects, power delivery, and thermal behavior. This holistic methodology ensures that all parts of the system are designed to work together efficiently, enabling better overall performance and energy efficiency. It represents a fundamental shift in how hardware systems are conceived and developed.

Summary

The future of AI hardware will not be defined by silicon scaling alone. Instead, it will be shaped by advances in packaging, interconnects, memory systems, and power efficiency, all brought together through system-level design. In this new paradigm, the system itself becomes the primary unit of innovation. Success will depend on the ability to integrate across multiple domains and optimize them collectively. As this transformation continues, it is clear that the “system” has effectively become the new chip, redefining how performance is achieved in the age of AI.

TSMC Advanced Technology Roadmap

At its 2026 Technology Symposium, TSMC delivered a clear message: the AI era has entered a new phase. The primary constraint is no longer model capability, but the systems required to run those models at scale. Addressing this shift will demand significant advances in semiconductor technology, spanning compute, memory, interconnects, and power efficiency.

From Model Scaling to System Scaling

Over the past several years, AI progress was largely driven by scaling models. In other words, expanding parameter counts, improving training methods, and unlocking new reasoning capabilities. That paradigm is now evolving. In 2026, the bottleneck has shifted to system-level challenges such as compute throughput, memory bandwidth, interconnect efficiency, power delivery, and deployment scale. AI is becoming fundamentally a systems problem rather than a purely algorithmic one.

This transition is especially visible in the rise of enterprise AI agents. These systems are moving beyond narrow task assistance to orchestrating workflows, integrating enterprise data, and enabling more autonomous decision-making. As a result, they require high reliability, strong security, and sustained performance, all of which significantly increase infrastructure demands.

Explosive Growth in AI Compute Demand

AI compute demand continues to grow at an extraordinary pace, driven by both training and inference. On the training side, large language models have already driven roughly fivefold annual increases in compute requirements. And the shift toward multimodal AI which combines text, vision, audio, and real-world signals, is accelerating this trend further. Training demand alone is expected to increase by another order of magnitude.

Even more striking is the growth in inference. Token generation has increased more than 500 times between 2022 and 2025, and new techniques such as chain-of-thought reasoning are significantly increasing compute per query. The emergence of agent-based AI systems could multiply this demand again, while large-scale multimodal deployments may push total inference workloads toward million-fold growth. As a result, inference is rapidly becoming the dominant driver of compute infrastructure expansion.

AI Is Expanding Beyond the Cloud

AI is no longer confined to centralized cloud environments; it is rapidly expanding into edge and physical domains. At the edge, inference is increasingly being performed directly on devices such as PCs, smartphones, and wearables. This shift enables lower latency, improved privacy, and real-time responsiveness, and is driving the widespread adoption of dedicated AI accelerators like NPUs in consumer hardware.

At the same time, physical AI is bringing intelligence into the real world through robotics and embodied systems. These applications require tight integration of AI with sensing, actuation, and real-time control, all within strict power and reliability constraints. Together, these trends highlight the growing need for silicon solutions that can balance performance, efficiency, and compact form factors across a wide range of environments.

Data Center Scaling Enters Hyper-Growth

The rapid expansion of AI workloads is fundamentally reshaping data center infrastructure. Annual capacity additions, which previously grew at a steady rate of around 5 to 6 gigawatts, are now expected to reach 30 to 40 gigawatts per year. At the same time, overall data center investment growth has accelerated from roughly 10 percent annually before the rise of generative AI to more than 30 percent per year through the end of the decade.

This growth is not just about adding capacity; it is about delivering efficient, reliable, and scalable systems. Energy efficiency and total cost of ownership are becoming central concerns, making semiconductor-level improvements critical to the sustainability of AI infrastructure.

A14: Next-Generation Logic Platform (2028)

A14 represents TSMC’s next major step in logic technology, combining second-generation nanosheet transistors with NanoFlex Pro architecture and continued backend scaling innovations. Compared with the N2 node, A14 is expected to deliver a 10 to 15 percent speed improvement at the same power or a 25 to 30 percent power reduction at the same speed, along with approximately 1.2 times the logic density.

A central innovation in A14 is NanoFlex Pro, which enhances standard cell architecture to improve area efficiency and performance per watt. This is complemented by significant backend scaling advancements, including tighter metal pitch and reduced minimum metal area, enabling higher transistor density and improved overall efficiency. Together, these innovations demonstrate that progress at advanced nodes now depends on full-stack optimization rather than transistor scaling alone.

A13 and A12: Extending the Platform

Building on A14, TSMC is extending its roadmap with A13 and A12 technologies, both targeted for production around 2029. A13 further improves density and efficiency while maintaining backward compatibility with A14, enabling smoother design migration for customers. A12 introduces backside power delivery, a major innovation that improves power integrity and performance by separating power and signal routing. These developments reflect a broader shift toward holistic scaling, where power delivery and system-level considerations play an increasingly important role.

N2 Family: Nanosheet Era in Production

The N2 node marks TSMC’s transition from FinFET to nanosheet transistor architecture, delivering improved electrostatic control, reduced leakage, and lower operating voltage. These benefits translate into tangible efficiency gains in real-world applications.

The N2 family includes several variants designed to address different performance needs. The base N2 node entered production in 2025, followed by N2P in 2026 as an enhanced version. N2X, expected in 2027, targets high-performance applications with additional frequency gains, while N2U, planned for 2028, integrates NanoFlex Pro enhancements to further improve performance and power efficiency. This expanding family underscores the importance of offering flexible solutions tailored to diverse workloads.

Advanced Packaging and 3D Integration

As AI workloads continue to scale, advanced packaging technologies are becoming as critical as process nodes themselves. TSMC is advancing its chiplet and 3D integration capabilities with improvements such as second-generation CoWoS technology, which reduces interconnect resistance and enables higher bandwidth through finer I/O pitch.

These innovations allow for denser integration of compute and memory, improving performance and energy efficiency at the system level. In the AI era, packaging is no longer a secondary consideration but a key enabler of overall system performance.

N3: Today’s Workhorse Node

While future nodes attract significant attention, the N3 family remains the backbone of current high-performance computing. It is widely deployed across mobile devices, CPUs, AI accelerators, and networking applications, with multiple variants such as N3P and N3C supporting different use cases. Strong customer adoption and a robust pipeline of new designs highlight the continued importance of mature leading-edge nodes in delivering value across the ecosystem.

Summary

TSMC’s roadmap reflects a fundamental shift in the semiconductor industry. As AI continues to scale, the primary challenge is no longer developing more powerful models, but building the infrastructure required to support them efficiently. This requires innovation across the entire technology stack, from transistors and interconnects to packaging and system architecture.

In this new era, success will depend on the ability to deliver not just better chips, but better systems. The companies that can integrate performance, efficiency, and scalability at every level of the stack will define the future of AI—and increasingly, that future is being shaped at the silicon level.
