Embedded memory makes computing applications run faster. In the early days of the semiconductor industry, the desire to utilize large amount of on-chip memory was limited by cost, manufacturing difficulties and technology mismatches between logic and memory circuit implementations. Since then, advancements in semiconductor… Read More

ReRAM Revisited
I met with Sylvain Dubois (VP BizDev and Marketing of Crossbar) at TechCon to get an update on his views on ReRAM technology. I’m really not a semiconductor process guy so I’m sure I’m slower than the experts to revelations in this area. But I do care about applications so I hope I can add an app spin on the topic, also Sylvain’s views on… Read More
Physical Design for Secure Split Manufacturing of ICs
Semiconductors are not only critical to modern life, semiconductors are critical to National Security. Now that leading edge semiconductor foundries have left the United States one of the more pressing challenges is secure semiconductor manufacturing. This applies to all countries of course so let’s take a look at the International… Read More
Where Circuit Simulation Model Files Come From
I started out my engineering career by doing transistor-level circuit design and we used a proprietary SPICE circuit simulator. One thing that I quickly realized was that the accuracy of my circuit simulations depended entirely on the model files and parasitics. Here we are 40 years later and the accuracy of SPICE circuit simulations… Read More
SPICE Model Generation by Machine Learning
It was 1988 when I got into SPICE (Simulation Program with Integrated Circuit Emphasis)while I was characterizing a 1.5 μm Standard cell library developed by students at my Alma-Mata Furtwangen University in Germany. My professor Dr. Nielinger was not only my advisor he also wrote the first SPICE bible in German language.… Read More
SEMICON West – Advanced Interconnect Challenges
At SEMICON West I attended the imec technology forum where Zsolt Tokei presented “How to Solve the BEOL RC Dilemma” and the SEMICON Economics of Density Scaling session where Larry Clevenger of IBM presented “Interconnect Scaling Strategic for Advanced Semiconductor Nodes”. I also had the opportunity… Read More
IMEC Technology Forum (ITF) – EUV When, Not If
For me personally EUV has been something of a roller coaster ride over the last several years. I started out a strong believer in EUV but then at the SPIE Advanced Lithography Conference in 2014 TSMC gave a very negative assessment of EUV, and there was a SEMATECH paper on high NA EUV that struck me as extremely unlikely to succeed. I … Read More
Samsung Versus Intel at 14nm
Daniel Nenni recently blogged about Intel’s claims of industry leading process density that were made at their analysts meeting. It isn’t clear to me why Intel makes this such a big focus at the analysts meetings, they really don’t compete with the foundries much but this seems to be a big deal to them. I thought it would be interesting… Read More
TSMC (Apple) Update Q2 2015!
The TSMC quarterly conference call was last week and of course it stirred up quite a bit of controversy. Let me share with you my experience, observations, and opinions and maybe together we can come up with an accurate prediction for 2016. First let’s take a look at 20nm and what people now call the “Apple effect.”
Correct… Read More
PDK Generation Needs Paradigm Shift
For any semiconductor technology node to be adopted in actual semiconductor designs, the very first step is to have a Process Design Kit (PDK) developed for that particular technology node and qualified through several design tools used in the design flow. The development of PDK has not been easy; it’s a tedious, time consuming,… Read More
