ESD path min

IC reliability is an issue that circuit design engineers and reliability engineers are concerned about, because physical effects like high Current Density (CD) in interconnect layers, or high point-to-point (P2P) resistance on device interconnect can impact reliability, timing or Electrostatic Discharge (ESD) robustness.… Read More

Synopsys 112G Ethernet PHY IP for VSR

Bandwidth, latency, power and reach are always the key points of focus when it comes to connectivity. As the demand for more data and higher bandwidth connectivity continue, power management is gaining a lot of attention. There is renewed interest in pursuing silicon photonics to address many of these challenges. There are many… Read More

NVM secret key storage problems

It’s a hostile world we live in, and cybersecurity of connected devices is a big concern. Attacks are rising rapidly, and vulnerabilities get exploited immediately. Supply chains are complex. Regulations are proliferating. Secrets don’t stay secrets for long – in fact, the only secret in a system with open-source algorithms… Read More

Innovation New

This is another look at refining the accuracy of fault localization. Once a bug has been detected, such techniques aim to pin down the most likely code locations for a root cause. Paul Cunningham (GM, Verification at Cadence), Raúl Camposano (Silicon Catalyst, entrepreneur, former Synopsys CTO and now Silvaco CTO) and I continue… Read More

FO WLP min

Our smart phones, tablets, laptops and desktops are the most common consumer products with advanced 2.5D and 3D IC packaging techniques. I love seeing the product tear down articles to learn how advanced packaging techniques are being used, so at the User2User conference in Santa Clara I attended a presentation from Tarek Ramadan,… Read More

Analog Bits Sensing SemiWiki

In a simple answer – everyone.  A keynote presentation “Sensing the Unknowns and Managing Power” by Mahesh Tirupattur, the Executive Vice President at Analog Bits at the recent Siemens User2User conference, discussed the need and application of sensors in computing and power applications. Why sense? As Mahesh explains, sensing… Read More

Predictive DPD virtual test bench

Next up in this series on modulated signals is an example of multi-dimensional EM design challenges: RF power amplifiers (PAs). Digital pre-distortion (DPD) is a favorite technique for linearizing PA performance. Static effects are easy to model and correct, but PAs are notorious for interrelated dynamic effects spoiling … Read More

SoCs Have Many Interfaces That Require Security

The never ending appetite for higher bandwidths, faster data interfaces and lower latencies are bringing about changes in how data is processed at data centers. The expansion of cloud to the network edge has introduced broad use of artificial intelligence (AI) techniques for extracting meaning from data. Cloud supercomputing… Read More


Double Diffraction in EUV Masks: Seeing Through The Illusion of Symmetry

Double Diffraction in EUV Masks: Seeing Through The Illusion of Symmetry
by Fred Chen on 05-22-2022 at 7:00 am

Double Diffraction in EUV Masks

At this year’s SPIE Advanced Lithography conference, changes to EUV masks were particularly highlighted, as a better understanding of their behavior is becoming clear. It’s now confirmed that a seemingly symmetric EUV mask absorber pattern does not produce a symmetric image at the wafer, as a conventional DUV … Read More

Ansys DAC 2022

The live events I have attended thus far this year have been very good. As much as I liked the virtual events, attending in the comfort of my home or sailboat, it is great to be live and networking inside the semiconductor ecosystem, absolutely.

Ansys has been a great supporter of the Design Automation Conference but this year they … Read More
