Slide3

I was asked to give a talk at the 2021 ISS conference and the following is a write up of the talk.

The title of the talk is “Logic Leadership in the PPAC era”.

The talk is broken up into three main sections:

  1. Background information explaining PPAC and Standard Cells.
  2. A node-by-node comparisons of companies running leading edge logic

No Intel and Samsung are not passing TSMC

No Intel and Samsung are not passing TSMC

Slide1

Seeking Alpha just published an article about Intel and Samsung passing TSMC for process leadership. The Intel part seems to be a theme with them, they have talked in the past about how Intel does bigger density improvements with each generation than the foundries but forget that the foundries are doing 5 nodes in the time it takes… Read More


Leading Edge Foundry Wafer Prices

Leading Edge Foundry Wafer Prices
by Scotten Jones on 11-06-2020 at 6:00 am

Slide1

I have seen several articles recently discussing foundry wafer selling prices for leading edge wafers, these articles all quote estimates from a paper by the Center for Security and Emerging Technology (CSET). The paper is available here.

My company IC Knowledge LLC is the world leader in cost and price modeling of semiconductors… Read More


Fully Self-Aligned 6-Track and 7-Track Cell Process Integration

Fully Self Aligned 6 Track and 7 Track Cell Process Integration

For the 10nm – 5nm nodes, the leading-edge foundries are designing cells which utilize 6 or 7 metal tracks, entailing a wide metal line for every 4 or 5 minimum width lines, respectively (Figure 1).

Figure 1. Left: a 7-track cell. Right: a 6-track cell.

This is a fundamental vulnerability for lithography, as defocus can change… Read More

TigerLake WillowCove

Summary
At the recent Intel Architecture Day 2020 symposium, a number of technology enhancements to the Intel 10nm process node were introduced.  The cumulative effect of these enhancements would provide designs with a performance boost (at iso-power) approaching 20% – a significant intra-node enhancement, to be sure.  The… Read More


Effect of Design on Transistor Density

Effect of Design on Transistor Density

TSMC N7 Density Analysis SemiWiki

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

Each year on the Sunday before the SPIE Advanced Lithography Conference, Nikon holds their LithoVision event. This year I had the privilege of being invited to speak for the third consecutive year, unfortunately, the event had to be canceled due to concerns over the COVID-19 virus but by the time the event was canceled I had already… Read More

I was asked to present at Nikon’s LithoVision event again this year. LithoVision is held the day before the SPIE Advanced Lithography Conference also in San Jose. The following is a write up of my talk.… Read More


IEDM 2018 Imec on Interconnect Metals Beyond Copper

IEDM 2018 Imec on Interconnect Metals Beyond Copper
by Scotten Jones on 12-28-2018 at 7:00 am

At IEDM this December Imec presented “Interconnect metals beyond copper – reliability challenges and opportunities”. In addition to seeing the paper presented I had a chance to interview one of the authors, Kristof Croes. Replacements for copper are a hot subject and I will summarize the challenges and Imec’s work.… Read More
