Yes, the process is longer but its better than nothing.Doable, but not very profitable or productive without EUV.
You're getting awfully excited about this story, this is the third time you've posted it today. This is a beat up, optical computing isn't new and has far too many drawbacks to replace semi-conductors. It's use is going to remain restricted to niche applications.good news! About EUV lithography machine, Tsinghua University made great contributions

Huawei's experience today has made many people aware of the importance of chips. If they cannot have an indispensable position in the chip field, then when other chip powers want to target us, we may not be able to fight back. Today Huawei is a living example.
In order to improve the autonomy of Chinese chips,last year, the state took the lead in establishing an integrated integrated circuit industrial base in Shanghai, aiming to build China's chip highland. At the same time, China's most powerful scientific research institutionChinese Academy of Sciences also announced an important decision to release a signal that the entire Academy will conquer core technologies such as lithography machines.
As we all know, in the chip production process, the lithography machine is the most critical equipment, and in the lithography machine, China is probably at the international intermediate level.At present, the most powerful lithography machine manufacturing company in China is Shanghai Microelectronics. The top lithography machine it can produce is a 22nm lithography machine, and the EUV light produced by the world's top lithography machine manufacturer ASML Compared with the engraving machine, there is still a certain gap.
Obviously, if China wants to gain a real say in the chip field, it must solve the problem of lithography machine.
Before that, the biggest obstacle that restricted China from building its own EUV lithography machine was the light source!
At this stage, the light source used in the lithography machine independently developed by China is deep ultraviolet light, while the light source required by the EUV lithography machine is extreme ultraviolet light.Although the difference between the two is only one word, it is not a simple matter to break through from deep ultraviolet light to extreme ultraviolet light.
Tsinghua University has done a great job!
If you want to make a domestic lithography machine, the first problem to be solved is the light source!What makes us happy is that on February 25th, good news came out suddenly. Regarding EUV lithography machines, Tsinghua University has done a great job!
It is reported thatTsinghua University has completed the first principle verification experiment of a new type of particle accelerator light source "Steady-state microbunching" (SSMB).
From the content of the related report,Based on the SSMB principle, we can obtain high-power, high-repetition, and narrow-bandwidth coherent radiation, and the wavelength can cover the band from terahertz to extreme ultraviolet (EUV).In other words, the verification of the SSMB principle indicates that Chinese scientists have found the direction to manufacture domestic EUV lithography machines, and continue to research and develop, and it is expected to produce real domestic EUV lithography machines.
Summary
Key technologies cannot be bought. If we cannot have the right to speak in the core technologies, then being stuck by other countries will become the norm.
It is not just a lithography machine. It is hoped that in other cutting-edge technology fields, Chinese scientists can also overcome the core difficulties as soon as possible and achieve true technological independence. A tribute to every Chinese scientist who silently contributes behind the scenes.
Finally,I also hope that domestic Internet giants can take a long-term view, make more contributions to the country's technological progress, do less loans, and compete with small businesses and hawkers. Food business.

Obviously, some troll want to play down the success. They are shaking now.This is about EUV Lithograpy (electronic computing), not optical computing. Please read it carefully
China make 3 different routes: conventional chip with EUV Litograhphy breakthrough, photonic chip, and graphene chips.
Photonic may not be in production yet, but graphene chips is closer.
Also if you read the article carefully, the niche market that you mention above is actually an opportunity to expand into wide application domination
