The latest news is that China's 7nm chips are manufactured using synchrotron radiation, which has 40 times the capacity of EUV lithography.

[CIA Mole]

Yes. In 2015, the Ninth Amendment to the PRC Criminal Law was adopted, which added into the PRC Criminal Law a new crime of spreading false information online or through other media(art. 291a). An offender can be punished by up to seven years’ imprisonment.

 

[MH.Yang]

The news comes from a product launch on 12 September 2023 reported by Huawei. Huawei mentions that they work with the Beijing Synchrotron Radiation Facility, BSF, on chips. Then the Chinese media enquired about its two factories in Xiongan and Shanghai, owned by CGST and Zhangjiang Hi-Tech, that can manufacture 7nm chips via synchrotron radiation.

The Beijing Synchrotron Radiation Facility, BSF, and Tsinghua University have collaborated to propose the SSMB-EUV light source solution (Steady State Microbeam), which overturns the concept of traditional lithography technology by no longer relying on shrinking the light source to improve the quality of the image, but rather, by enlarging and elongating the light source, to achieve the automatic adjustment of the different wavelengths of light, so as to achieve a higher degree of precision.

Of course, all the news now comes from the unofficial media splicing bits and pieces together and making guesses. It has not been confirmed by official organisations such as Huawei or Tsinghua University. I can understand if people don't believe it.

In June 2021, the official Chinese government media reported on the completion of the construction of the SSMB-EUV light source factory:

In February 2023, a press release from Tsinghua University's official media stated that the university's SSMB-EUV light source solution and technology had been put to practical use after spending 10 years and had solved a problem that was a major national need in the field of photolithography:

BTW: According to experts in the field, if synchrotron radiation technology is used, it can achieve a 1NM effect with a 7NM stack, with the drawback of only a slightly higher heat generation.


BTW: Such a factory is something that only China is capable of building. Not only does it require a lot of industrial support and a lot of capital investment, it also has a lot of unique technologies and patents in the hands of Chinese state-owned enterprises. For example, 100,000 KW of power needs to be transmitted by ultra-high voltage, which is a unique technology and patent of China's power grid. The vast majority of countries, including the United States, do not have ultra-high voltage power grids, and China is the only country that has the ability to build such a plant.

Theoretically it is possible since our weakness is in shrinking the component size. We are compensating this by using another approach. Instead of killing a mosquito with a small tennis racquet, we are using a big racquet the size of a room.

Some people know very well that the Chinese Government is very far-sighted and often engages in very long-term planning. But they still believe that Beijing was not ready to deal with the semiconductor issue until the United States launched sanctions.

Some know that China is the only country with a complete industrial chain, and that its industrial scale and research capabilities are much larger than those of the Netherlands. But they still believe that China will use the same methods as the Netherlands to manufacture semiconductors.

This will buy us time to miniturize the components further. Coupled with chiplet tech, Huawei has a big chance to win this race.

Well, this is good news!

I thought Huawei 7nm is not sustainable.

I think China technology advancement is no longer tied to the West. Instead of trailing behind or collaborating, China is able to take another path.

Since China research is already the world biggest, that explain everything.

Amazing! China is one step ahead again.

Yes, based on my observation for years, China government is far sighted and do long term planning.

It's always went to the basic first, then stepping the ladder one by one.

Chinese government is also love to do social and economic experience, like setting up special zones with special social and economic policies. If it's successful, then it will be implemented national wide.

Xi is great. He is a rare person.

Almost all Chinese leaders and high-rank officials are great.

Because they are selected through meritocracy over hundreds of millions of people.

Some of them even have supranatural capabilities, have a unique brain, that explains why they are able to excel and win the meritocracy competition.

They have capabilities and know their job very well, that makes them different from the politicians from other countries.

"In relatively low price"

Again, every time I read China research report, I see a lot the words of "low price".

It's truly helping humanity, improving everyone's standard of living.

Will it reduce cost for everything in future?

Any innovation is good Innovation.

Any area where China joins in will result in a price dafu drop.

Thanks for posting this. I have met a lot of really smart Tshingua graduates, so I have great respect for this university. However, the leap from research in a university and commerical production is a big one and your posts don't provide enough authoritative information to demonstrate this has been done. My main concern is what the unit cost of production will be, taking into account capital costs. The chips in the new phone carry the SMIC label. How is SMIC involved in the process you have described ? Also please see a report on statements made by a Tshingua professor:

Goals of 'Made in China 2025' Are Unachievable: Tsinghua Professor

China can currently produce 41.4% of its chip needs.

It is difficult to reconcile the publicly available information with what you are reporting. If you have anything reported by Huawei, SMIC or Tshingua with details, please share it.
