Exciting times for the semiconductor industry! Last week Intel announced a billion dollar fund to build a foundry ecosystem and today Intel announced they are acquiring foundry Tower Semiconductor for $5.6 billion dollars, WOW! Some people doubted Intel’s commitment to the foundry market this time. I think we can now put that… Read More
The Semiconductor Ecosystem Explained
The last year has seen a ton written about the semiconductor industry: chip shortages, the CHIPS Act, our dependence on Taiwan and TSMC, China, etc.
But despite all this talk about chips and semiconductors, few understand how the industry is structured. I’ve found the best way to understand something complicated is to diagram… Read More
Samsung Keynote at IEDM
Kinam Kim is a longtime Samsung technologist who has published many excellent articles over the years. He is now the Chairman of Samsung Electronics, and he gave a very interesting keynote address at IEDM.
He began with some general observations:
The world is experiencing a transformation powered by semiconductors that has been… Read More
ASML Too Much Demand Plus Intel and High NA
Too much demand- A “good” problem-Managing supply & capacity-Intel & Hi NA
–ASML great Q4 results-Demand off charts-Supply constrained
-Dealing with chain issues, putting out fires, expediting
-Looking forward to next gen High NA in 2024/2025
-Intel’s order doesn’t give advantage,… Read More
TSMC Earnings – The Handoff from Mobile to HPC
Hello! The most important semiconductor company in the world reported earnings last night. It’s been something of a tradition to post Taiwan Semiconductor Company (TSMC) earnings posts not behind my paywall, and I think that I’m going to continue that to kickoff each earnings season.
There are so many threads in the TSMC call that… Read More
Forty Four Billion Reasons Why TSMC Remains Dominant
-Chips for America is better than nothing, but not much
–TSMC $40-44B Capex crushes competition (Intel & Samsung)
-Additional efforts other than handouts are necessary
-Could/should TSMC be “adopted” as a US company?
Competition can’t keep up with $40-$44B of Capex
TSMC’s recent announcement… Read More
Self-Aligned Via Process Development for Beyond the 3nm Node
The further scaling of interconnect and via lithography for advanced nodes is challenged by the requirement to provide a process window that supports post-patterning critical dimension variations and mask overlay tolerances. At the recent international Electron Devices Meeting (IEDM) in San Francisco, TSMC presented … Read More
Technology Design Co-Optimization for STT-MRAM
Previous SemiWiki articles have described the evolution of embedded non-volatile memory (eNVM) IP from (charge-based) eFlash technology to alternative (resistive) bitcell devices. (link, link)
The applications for eNVM are vast, and growing. For example, microcontrollers (MCUs) integrate non-volatile memory for … Read More
Advanced 2.5D/3D Packaging Roadmap
Frequent SemiWiki readers are no doubt familiar with the advances in packaging technology introduced over the past decade. At the recent International Electron Devices Meeting (IEDM) in San Francisco, TSMC gave an insightful presentation sharing their vision for packaging roadmap goals and challenges, to address the growing… Read More
Intel Discusses Scaling Innovations at IEDM
Standard Cell Scaling
Complex logic designs are built up from standard cells, in order to continue to scale logic we need to continually shrink the size of standard cells.
Figure 1 illustrates the dimensions of a standard cell.
Figure 1. Standard Cell Dimensions.
From figure 1 we can see that shrinking standard cell sizes requires… Read More
