-ASML weakness is evidence of deeper chip down cycle
-When ASML sneezes other chip equip makers catch a cold
-Will backlog last long enough? Will EUV demand hold up?
-“Unthinkable” event, litho cancelations, could shock industry
ASML reported Euro6.7B… Read More
Normalized image log-slope (NILS) is probably the single most essential metric for describing lithographic image quality. It is defined as the slope of the log of intensity, multiplied by the linewidth [1], NILS = d(log I)/dx * w = w/I dI/dx. Essentially, it gives the % change in width for a given % change in dose. This is particularly… Read More
The SPIE Advanced Lithography Conference is the semiconductor industries premier conference on lithography. The 2023 conference was held the week of February 27th and at the conference Applied Materials announced their Sculpta® pattern shaping tool. Last week I had an opportunity to interview Steven Sherman the Managing … Read More
-We attended the SPIE lithography Conference in San Jose
-No significant news or announcements on EUV
-Focus on 500WPM target and High & Hyper NA rollout
-AMAT overblown Sculpta-Not exactly what its cracked up to be
We have been attending SPIE for many years now and are happy to see a return to pre Covid levels… Read More
The many idiosyncrasies of EUV lithography affect the resolution that can actually be realized. One which still does not get as much attention as it should is the cross-slit pupil rotation [1-3]. This is a fundamental consequence of using rotational symmetry in ring-field optical systems to control aberrations in reflective… Read More
-US, Japan & Dutch agree to embargo some China chip equip
-Goes beyond just leading edge & will increase negative impact
-China might catch up in decades or invade Taiwan tomorrow
-Why the memory downturn could be longer than expected
It appears that the US has put together a coalition of the US, Japan and… Read More
-Demand far exceeds supply & much longer than any downturn
-Full speed ahead-$40B in solid backlog provides great comfort
-ASP increase shows strength- China is non issue
-In a completely different league than other equipment makers
Revenues were Euro6.4B with system sales making up Euro4.7B… Read More
Stochastic defects in EUV lithography have been studied over the last few years. For years, the Poisson noise from the low photon density of EUV had been suspected [1,2]. EUV distinguishes itself from DUV lithography with secondary electrons functioning as intermediary agents in generating reactions in the resist. Therefore,… Read More
My name is Sagar, and I’ve been a long-time executive in the semiconductor manufacturing world — holding key positions at large multi-nationals, a leading semiconductor foundry, and partnering with many of the top-tier foundries and OSATs. Since “retiring”, I’ve also spent time advising and investing in start-ups through … Read More
Recently TechInsights analyzed a Bitcoin Miner chip fabbed at SMIC and declared SMIC has a 7nm process. There has been some debate as to whether the SMIC process is really 7nm and what it means if it is 7nm. I wanted to discuss the case for and against the process being 7nm, and what I think it means.
First off, I want to say I am not going … Read More
