I work for on of the support manufacturers you listed, Tokyo Electron. ASML's scanners really are a sight to behold as they're being installed, truly marvels of engineering. Our tools are extremely well built as well, and are fascinating to watch when they're working. The speed with which they transfer wafers to the many steps of the photolithography process, including the scanner, is something out of a sci-fi film.

@michaelkeudel8770 - 2023-10-24

I've been on the prototyping/building/design side of of Intels EUV Vaccum Control System for almost 8 years now, multiple revisions, tweaking, process updates, it never ends. But I'm the only one in my group that knows what the ASML Lithography machine actually is, and that I tie into that machine to make it function. All because 8 years ago I was asked if I want to take on the challenge of prototyping the first version based on terrible drawings and documentation, and I said yes, and somehow the whole project dropped into my lap instead of getting laid off when they moved production out to the new Oregon Facility. I went out there for 3 months to train my replacements, and came home to a work from home job I wasn't expecting, it all worked out in the end 🙂

I was surprised to learn ASML has really only been in their forefront position since the latter years of the 2010s i.e. about half a decade now. The way they're talked about nowadays you'd think they were this hitherto little known (cos semiconductor supply chains only became a hot topic recently due to geopolitical tensions) but key player in the global tech economy, but no they only really rose to prominence recently (rose, not founded, that happened all the way back in 1984). EUV is literally the one big thing that makes them important now, which they got into thanks to acquisitions, they weren't anything too important before it. Which also means if the technology in semiconductors changes again, ASML will be left in the dust (unless they can use their newfound position to keep up with the changing trends in the industry).

@Grak70 - 2023-02-03

ASML was and is huge in all previous UV step and repeat systems. They just have competition in that arena. There are ASML I-line steppers where I work that were built in the early 1990s with Zeiss optics stamped “made in West Germany”.

Another fascinating piece, great work as always!

One note: You said that the discs that picked up the molten tin were 20 meters in diameter, is that correct? If so, that’d require an absolutely enormous high-vacuum system to house them!

I’m curious where the carbon contamination on the mirrors came from: Maybe minuscule amounts of diffusion-pump oil? I’m intrigued as to where the hydrocarbons might have entered the system.

I was in the camera biz at the time, and the global crash of 2008 hit Nikon pretty hard too, so that might have been a factor in limiting their appetite for lithography R&D as well.

Nikon’s an interesting and sad story that would make an interesting video of its own (if you haven’t already done one). A lot of things combined to create an almost perfect storm of problems for them in the 2016-2017 time frame. In 2017 they took an extraordinary accounting charge for their semiconductor lithography division, essentially saying in financial terms that they’d never recoup the capital cost of their manufacturing facilities even in terms of gross revenue, let alone profits :-0

Leading up to that, their camera division had two disastrous technology failures in 2016-2017, both of which could be laid at the feet of their development partners, but that Nikon ultimately paid the price for.

The first was their ill-fated “Key Mission” action camera line. This consisted of three models, the 80, 170 and 360, the numbers referring to the angular field of view. (The 360 captured 360-degree stills and videos.) The hardware and optics of these were excellent, well ahead of anything GoPro or others had at the time, with the optics in the 360 being little short of amazing. Unfortunately, the firmware and software were another story entirely, to the point that they were almost unusable. (The WiFi connectivity was particularly bad.) I don’t know but suspect that some chunk of the software development was contracted out, but however it was done, it killed the products. This was especially unfortunate because Nikon had invested a huge amount in development, having decided that action cams were a critically important market for them to enter. They also spent some enormous amount in a global marketing campaign to launch them. It’s possible that they might have eventually recovered and gotten things working, but as we now know, this was just as the action camera market hit saturation and sales were falling off a cliff.

The second critical blow was to their planned DL camera line. These were very high-spec compact cameras (meaning with non-interchangeable lenses) that were intended to compete with Sony’s very successful RX-series models. The specs looked great, and the optics would undoubtedly have been first-rate. They went through the entire development process, right to the point of being ready to go into mass production, only to discover that the (unknown) third party responsible for the image processors couldn’t deliver on them (!). They were so far along they’d even placed ad contracts for the product launch, only to have to cancel them a month or two later, before any ads aired. I never found out what the specific problem was with the processor chips, but I’m guessing that the supplier designed them around a process node that wasn’t stable yet so they couldn’t get the yields they needed to manufacture them. (This is entirely speculation on my part, all I know for sure is it was the processors that killed the line. They were originally slated to launch in June 2016, but it took until February 2017 for Nikon to officially announce their demise.

Both sets of products held a lot of promise and I’m sure would have been quite profitable if they’d been able to successfully produce them. I wonder where Nikon would be today if they hadn’t lost so much investment and opportunity cost on these two products. As a longtime Nikon fan, it saddened me to see them have such struggles :-/

(The whole evolution of the camera business is a pretty interesting subject; there have been a lot of twists and turns along the way as the tech moved from analog to digital.)

At a very simplified level, they use bands of closely spaced electromagnets to move the stage (the entire stage is levitating over a near perfectly smooth block of granite). The closed loop control uses an interferometer and powerful signal processing to feedback an electrical signal to those magnets that results in oscillation damping and acceleration control. The part of every stepper/scanner you don’t see is the rows of 2m tall control racks supporting it. They’re usually tucked away in the sub-fab, quietly and frantically sending out a flood of information to the control systems. It is truly mind boggling.

If we look to Shuji Nakamura who won the Physics Nobel prize for his work inventing the blue LED, it was a small team of inventors who did not have significant support who invented the tech. Large consortiums are slow and I think rarely succeed because of the internal inertia and politics. MITI should have tasked multiple teams to work on the various sub systems. Consortiums don't allow for fast decisions, etc.

@slash2bot - 2023-02-04

These are not technologies that can be made by just one research team. It is an extremely complex set of technologies, all niche, which have to work together perfectly for even a prototype to work. Consortium is the only way. Plus developing even a single technology component is extremely expensive, and so requires governmental help.

The monopoly in the industry could be detrimental to the resiliency of it.
It's clear that these things have become primordial assets with enormous geopolitical value
and there is a clear effort to prevent the advancement of alternative technologies for strategic reasons.

@blahblahblah23424 - 2023-02-06

Seems like most assessments concluded that proximity x-ray would have been the best, and most scalable technology. But having to build synchrotrons scared people away. I think in the end the joke may be on them. EUV is expensive, inherently not very scalable, and ultimately took decades to develop. Hard to see how the same investment in x-ray based lithography wouldn't have everyone better positioned by now...

@xBlackWind - 2023-02-12

China is developing a synchrotron radiation based steady state electron microbunching EUV, different from the Free electron laser based Laser pulsed plasma EUV used by ASML. The SSMB EUV can give a much high power radiation along with a much more stable and efficient performance at a reasonable cost. Tsinghua University along with Helmholtz-Zentrum Berlin has already verified it's proof of principle. Further research is ongoing at Tsinghua University, a prototype is supposed to come out by 2026 and commercialization within this decade.

@gorkarullan - 2023-04-08

I really like your videos, my father worked for several Japanese companies, NEC, Nikon, I know he also works with several universities, etc... My father was involved in some of the processes of the machinery you mention, especially in defects ... I really liked it because some of the solutions you mentioned came from my father's group.
My father always said that the Japanese were hard workers, but sometimes they weren't very smart. They had a hard time being imaginative in finding solutions to problems.
My father then went to a European company, although I think he was working for IBM or Intel... and then he retired.

But this video has made me very funny, I still remember my father's discussions about some of those issues and how hard it was for them to solve the problems.

Very likely there will be no post EUV lithography, cause smaller you get, bigger problems with electrons migration become, making chips less durable, but with higher price. Would you like to have 1nm CPU with lifetime of 2-3 years and 1500-2000$ price or 20nm CPU with 10 years lifetime and 500-1000$ ?

I think it is worth pointing out as the historical context that GaAs research at the Japanese national lab was banned after Cray failed to produce HPC system based on GaAs chip and accused Japanese government for subsidizing the Japanese computer companies R&D. Well, I suppose it has to be explained why this accusation was accepted, which is rather something to do with the conflict between communist regime and capitalist regime. Also, what the US government did in order to hold some former enemies as their allies (part of capitalism regime), which backfired as disadvantage to domestic industries.
