EUV is just research by a dozen Chinese institutes developing different parts, the evidence support that neither SMEE or their subsystems-parts suppliers is involved in that project for now,
@tokenanalyst bro because the EUVL project is part of the 14th 5 year plan (2020-2025) so funds are allocated to different Scientific Institution, so SMEE will be consulted as reported that 2 of the 3 crucial components the Optics/Lens and Dual Bench had been successful research and develop, only the light source is delayed as they discard using DPP and focus on SSMB instead.
looks like they have most of their resources into immersion.
The by product of the 13th 5 year plan (2015-2020), harvesting time as SMEE gather all the components successfully develop under the plan to created SSA800 DUVL.

".... only the light source is delayed as they discard using DPP and focus on SSMB instead. "

I wonder if they did proceed with building the EUVL with the available DPP (for testing as well as special uses), albeit with lower power than the optimum. This would mean a compromised efficiency on wafer production but would allow access to the higher end node process nonetheless.

My way of thinking is that the light source Power is correlated to the speed of wafer production and not on the node resolution since it mostly have to do with the wavelength of the lightsource?

China’s major telecom operators are increasing the proportion of servers they buy that are powered by domestic chips, a move that experts said reflects their concerns about potential risks in China-US relations. It also shows that domestic chip technologies are quickly maturing, fueled by rising market demand.

The country’s three major telecommunications operators have all disclosed the results of their latest server bid. Of the first batch of portable computer servers ordered by China Mobile in the 2021-2022 period, about 27 percent are powered by domestic chips, namely Huawei’s Kunpeng and chips made by Chinese tech giant Hygon.

This shows a rising proportion of domestic servers in the telecom giant’s purchasing layout, as PC servers powered by domestic chips only accounted for about 20 percent of the company’s overall PC server orders in 2020.

China Telecom ordered 53,401 servers powered by domestic chips for the 2022-2023 period, according to a statement they published recently. This is a significant increase from the 24,823 domestic servers they purchased in the 2020-21 period. However, the proportion has dropped somewhat to 26.7 percent from 35.5 percent.

China Unicom also purchased a large number of artificial intelligence (AI) servers powered by domestic chips, mostly Huawei Shengteng chips, in their 2022 bid. Domestic AI servers account for about 33.3 percent of their overall purchasing.

Experts attributed this phenomenon to the fact that domestic telecom companies are feeling increasingly insecure about relying on overseas servers after many Western countries showed an increasingly hostile attitude toward China, and high technology is one of the areas that is most vulnerable to external sanctions.

“China-US relations have become complicated, so companies are looking to multiply their purchasing channels in order to reduce risks,” Fu Liang, a veteran TMT analyst, told the Global Times on Monday.

Domestic chip technologies are also maturing rapidly, and Chinese companies are capable of replacing a certain portion of overseas chips.

According to Fu, China’s chip design has attained a medium- or high-level standard compared with overseas companies. Product research and development is progressing, while software has also reached a high level, he said, adding that the bottleneck now mostly lies in the manufacturing side.

Even the problem with chip manufacturing is also on the verge of being solved, thanks to the collective efforts from government and market resources in recent years, experts said. For one thing, China’s rapid surge of demand for terminal electronic products has been stimulating progress in upstream technologies, and much progress has already been made in manufacturing of certain chips, such as those used for industrial controllers and home electric appliances. The whole chip industrial chain is developing, which creates a positive environment for technological breakthroughs.

“A batch of companies are doing business related to chip industrial chains, and this collective force makes it easier to make breakthroughs in critical areas, like high-end chip manufacturing,” Fu said.

Tech analyst Xiang Ligang said that one problem with domestic server supplies is that they are not stable enough, as the US sanctions on Huawei also restricted their production of Kunpeng chips. “Currently, they might be selling previous stock, but I guess there is not much inventory left,” Xiang told the Global Times.

But Xiang is also optimistic that China’s chip production technologies will see breakthroughs in the next few years, and once that happens, the proportion of domestic servers are likely to increase further in Chinese clients’ supplier list.

the node resolution since it mostly have to do with the wavelength of the lightsource?
A bit more complicated than that, a course shorter wavelengths means lower node resolutions but also depend on the on techniques like computational lithography, multiple patterning, phase shift masks, better optics (better NA), high-index immersion, better photoresist. EUV just means fewer tricks.
Skepticism is welcomed but in my personal view I think Tsinghua is into something with SSMB EUV, I read that they are looking for ways to path the laser like light to a mask, collectors mirrors are a huge deal in the reflective optics on LPP sources. I know there is a lot more variables to take into account to have something production ready, so we have to wait and see if they can make a prototype system.

Interesting video Russians discussing the possibilty of making a completely home-grown smartphone after this sanction

The video is in Russian language,you can turn on the subtitle and choose english translation

It only gives me an option of Russian language for subtitles.

In any case, this homegrown smartphone thing is bs. At most I can see a domestic assembly of smartphone

Yes, I'm aware of the above.

What I meant was a lower-powered LPP shouldn't prevent them from achieving the higher resolution required, other than having to compromise with the lower wafer productivity related to low power, provided of course all the other requirements / techniques, as specified above, have also been taken care of.

There is no need.

Even in the worst case there are loads of gray market small mom and pop manufacturers in China outside the Western supply chain which could easily make a 4G phone using all Chinese components with 0% US content. You just need to go to Shenzhen and check it out.

The best the Russian industry could make would be even worse than that. They could in theory make an early generation smartphone but it would be a waste of fab space and making a dumb phone would be much more practical if it ever came to be the case they stopped having access to external markets.

An EDA tool for e-beam lithography (EBL) developed at Hunan University (HNU)

1647996131707.png

The EBL-oriented EDA software tools are indispensable to design and manufacture EUV/DUV masks or sub-10 nm prototype devices. Some international treaties (e.g., 3.D.1-3 of Wassenaar Agreement [1]) and national laws (e.g., 3D003 of U.S. export control laws [2]) impose controls on exporting EBL-oriented EDA software tools to certain countries like China, Russian, etc.

We believe that EBL technologies should be used as friendly tools to improve lives of people from all countries without discrimination, rather than hostile weapons to deter the development of any country. Therefore, we are trying to develop these EBL EDA tools from scratch by ourselves. We license HNU-EBL EDA software, free of charge, to anybody from anywhere. To obtain a license, please click “license” and “contact us” on the top.

If that is not a giant middle finger, i don't know what else it is.
