In January I presented at the ISS conference a comparison of Intel’s, Samsung’s and TSMC’s leading edge offerings. You can read a write-up of my presentation here.
With the problems going on at Intel, that article generated a lot of interest in the investment community, and I have been holding a lot of calls with analysts who are trying… Read More
At the SPIE Advanced Lithography Conference held in February, ASML presented the latest information on their Deep Ultraviolet (DUV) and Extreme Ultraviolet (EUV) exposure systems. I recently got to interview Mike Lercel of ASML to discuss the presentations.
DUV
Despite all the attention EUV is getting, most layers are still… Read More
-KLAC- Solid QTR & Guide but flat 2021 outlook
-Display down & more memory mix
-KLAC has very solid Dec Qtr & guide but 2021 looks flattish
-Mix shift to memory doesn’t help- Display weakness
-Despite flat still looking at double digit growth
-EUV driven business may see some slowing from digestion
As always, … Read More
– ASML has good quarter driven by DUV & Logic (@72%)
– SMIC & other major customer slow EUV plans
– Logic (read that as TSMC) remains key demand led driver
– We are happy memory remains muted given cyclical potential
A very solid quarter with a continued road to growth
The quarter came in at Euro4,254B… Read More
For advanced lithography used to shrink semiconductor device features according to Moore’s Law, resolution limits are an obvious consideration. It is often perceived that the resolution limit is simply derived from a well-defined equation, but nothing can be further from the truth.
Ongoing investigations of EUV stochastics [1-3] have allowed us to map combinations of critical dimension (CD) and pitch which are expected to pose a severe risk of stochastic defects impacting the use of EUV lithography. Figure 1 shows a typical set of contours of fixed PNOK (i.e., the probability of a feature being Not OK due… Read More
KLA reported revenue of $1.54B and Non GAAP EPS of $3.03 versus street expectations of $1.49B and EPS of $2.77. Guidance is for revenues… Read More
ASML hits great numbers
ASML reported revenues of Euro 4B, with income of Euro 2.54EPS, both beating estimates handily. Ten EUV systems were … Read More
Recently, TSMC held their 26th annual Technology Symposium, which was conducted virtually for the first time. This article is the first of three that attempts to summarize the highlights of the presentations.
This article focuses on the TSMC process technology roadmap, as described by the following executives:
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
