Summary
A recent process enhancement in advanced nodes is to support the fabrication of contacts directly on the active gate area of a device. At the recent VLSI 2020 Symposium, the critical advantages of this capability were highlighted, specifically in the context of the behavior of RF CMOS devices needed for 5G designs.

Having spent the last 30 years in semiconductor manufacturing, eight years of this living and working in Asia, it is both exciting and unsettling to see renewed political interest in the revitalization of this industry in the United States. Gone are the days of ‘It doesn’t make any difference whether a country makes computer chips… Read More
Summary
The growing significance of ultra-short reach (USR) interfaces on 2.5D packaging technology has led to a variety of electrical definitions and circuit implementations. TSMC recently presented the approach adopted by their IP development team, for a parallel-bus, clock-forwarded USR interface to optimize power/performance/area… Read More
Intel comes late to the game but will be delivering an embedded defense for Return Oriented Programming (ROP) types of cyber hacks. I first blogged about this back in Sept of 2016. Yes, almost four years have passed and I had hoped it would see the light of day much earlier.
The feature, to debut in the Tiger Lake microarchitecture… Read More
Summary
As a result of extensive focus on the development of workfunction metal (WFM) deposition, lithography, and removal, both FinFET and gate-all-around (GAA) devices will offer a wide range of Vt levels for advanced process nodes below 7nm.
Introduction
Cell library and IP designers rely on the availability of nFET and pFET… Read More
Summary
A novel spin-transfer torque magnetoresistive memory (STT-MRAM) IP offering provides an attractive alternative for demanding high-performance embedded applications.
Introduction
There is a strong need for embedded non-volatile memory IP across a wide range of applications, as depicted in the figure below.
The… Read More
I have written a lot of articles looking at leading edge processes and comparing the process density. One comment I often get are that the process density numbers I present do not correlate with the actual transistor density on released products. A lot of people want to draw conclusions an Intel’s processes versus TSMC’s processes… Read More
The current Coronavirus crisis is inflicting a lot of pain on people, companies, and governments. I hope I am not getting in trouble with my reasoning, but if you look closely, there are also some “positives” to the Covid-19 crisis.
– It is stress-testing our infrastructure and telling us where we need to improve – as country,… Read More
On May 15th TSMC “announced its intention to build and operate an advanced semiconductor fab in the United States with the mutual understanding and commitment to support from the U.S. federal government and the State of Arizona.”
The fab will run TSMC’s 5nm technology and have a capacity of 20,000 wafers per month (wpm). Construction… Read More
-Could GloFo come back?
-TSMC or Intel or both or neither?
-Samsung would be a long shot?
-Perhaps Apple could convince TSMC?
The Wall Street Journal put out an article that detailed what we had indicated in our newsletter 10 days ago, that the US government is looking at getting a US based foundry to protect our interests given our … Read More
