They also do less advanced multi-axis motion stages (50-100nm in precision) for high precision manufacturing in other areas.
My guess packaging, micro-manufacturing, power and others.

yes, 1 beamline = 1 EUV machine. Here's a diagram of what a synchrotron beamlines looks like.
It would change fab layout and increase fab construction costs. It would also increase the difficulty of multiple EUV steps, since 1 mask = 1 step = 1 layer. However, in exchange you can have economies of scale with multiple EUV optics sets being serviced with 1 synchrotron. How many EUV instruments do you need?
At some point the cost of adding another EUV source (~$50 million per source) will outweigh the cost of having 1 big synchrotron ($172 million per 8 beamlines for the Shanghai synchrotron or $25 million per source if you use all 8).
Also a single synchrotron could be shared between few EUV and research facilities, so it may potentially end up the research facilities get it for free for a few beamlines ... win win

Xinjiang is interesting place for semiconductor capital, as long as there is enough clean water for it.
But China is huge huge country, so many huge land available even near the coastal regions. I suspect near main river like Yangtze, may be better place for it

Do Chinese companies buy DUV machines from Nikon or Canon ? is there any restrictions?
I dont like to post from twitter but a few years ago i predicted to someone that US sanctions to Huawei are gonna cause a blowback and are going to fuel the Chinese semiconductor industry.

I don't think so. The biggest buyer of Nikon DUV is Intel, they only sell a few dozen instruments per year (to Intel) and Canon DUV is outright worse than SMEE DUV. It use to be that DUV had multiple competitors in the early 2000's but Canon never got into ArF lithography and Nikon never got into EUV.
This means that in reality, ArF lithography is only between ASML, Nikon and SMEE.
Russia could hit U.S. chip industry, White House warns
WASHINGTON, Feb 11 (Reuters) - The White House is warning the chip industry to diversify its supply chain in case Russia retaliates against threatened U.S. export curbs by blocking access to key materials, people familiar with the matter said.
The potential for retaliation has garnered more attention in recent days after Techcet, a market research group, published a report on Feb. 1 highlighting the reliance of many semiconductor manufacturers on Russian and Ukrainian-sourced materials like neon, palladium and others.
According to Techcet estimates, over 90% of U.S. semiconductor-grade neon supplies come from Ukraine, while 35% of U.S. palladium is sourced from Russia.
Peter Harrell, who sits of the White House's National Security Council, and his staff have been in touch with members of the chip industry in recent days, learning about their exposure to Russian and Ukrainian chipmaking materials and urging them to find alternative sources, the people said.
Neon, critical for the lasers used to make chips, is a biproduct of Russian steel manufacturing, according to Techcet. It is then purified in Ukraine. Palladium is used in sensors and memory, among other applications.
What the hell. Is this forum an advertisement for U-precision . This is the 4th time someone has posted this article. Please don't send it again .
4th time? I did a search and found no other posts. Also, I do not advertise, this is just a post to give an insight on what China's SME industry is working on.
@tokenanalyst Don't mind him bro, your contribution to this forum is top notch and I'm one of your fan.
keep up the good work!- Status
