To be small is glorious , let a Ten thousand companies bloom! ;)

China has named nearly 9,000 ‘little giants’ in push to preference home-grown technologies from smaller companies​

  • Beijing has named 8,997 industrial enterprises as ‘little giants’, about 90 per cent of its goal to have 10,000 such companies by 2025
  • Designated small and medium-sized companies are eligible for preferential treatment as long as they show strength in strategically important areas

”, which are eligible for preferential treatment to help the country become a stronger technological powerhouse in its competition with the US.
The data was disclosed during a national summit of little giants that kicked off on Thursday in Nanjing, capital of eastern Jiangsu province. President Xi Jinping said in a letter that he hopes such enterprises will “play a more important role in stabilising supply chains and promoting economic and social development”.
The summit also revealed that such companies made an average profit of 40 million yuan in 2021, more than three times the figure of small and medium-sized enterprises with annual revenue of at least 20 million yuan.

Little giants are smaller and often little-known businesses that have special products and know-how in strategic sectors like semiconductors, advanced manufacturing, energy and critical minerals. They have so far established more than 10,000 research institutes at state and provincial levels.


These companies have an average of 28.7 per cent of their employees working in research and development, in line with the 30 per cent rate for companies listed on the Shanghai Stock Exchange’s Science and Technology Innovation Board, known as the STAR market, according to state-owned Economic Daily.
In just three years, China has reached 90 per cent of its goal to name 10,000 little giants by 2025. Since 2019, Beijing has published four lists of companies designated as little giants, also referred to as “specialised and sophisticated enterprises”.

To be designated a little giant, a company must operate in strategically important industries, which includes software and artificial intelligence. They also need to be able to “fix weaknesses” in the domestic supply chain, according to the application form from the Ministry of Industry and Information Technology (MIIT).
China has felt a greater urgency to promote domestically developed technologies as an escalating

has restricted access to certain supplies. From January through August, China’s import volume of integrated circuits (ICs)

to 369.5 billion units, according to data from the General Administration of Customs.

MIIT minister Jin Zhuanglong vowed on Thursday to “improve the regulatory system” and “accelerate the introduction of supporting institutional measures to encourage innovation, financing and promotion”.


Officially recognised little giants can enjoy lucrative incentives from the central and provincial governments, including tax cuts, generous loans and favourable talent acquisition policies, but there is no standard incentive package.

The central government plans to set aside 10 billion yuan to support more than 1,000 little giants between 2021 and 2025, according to a document in early 2021.

Some background information on the little-giant policy.

It seems China policymakers have been inspired by German model of 'hidden champion'.

"The term 'hidden champion' concept was proposed by Hermann Simon, founder of Simon-Kucher & Partners. There are three criteria: first, they occupy the leading position in the industry; second, they generally have USD 2 billion revenue; third, although it is famous in its professional micro-sector, it is not known by the general public. At present, there are about 2,734 hidden champions in the world, and Germany developed 1,307 of them, ranking top in quantity."

I can confirm the German model, due to my job I know well some example of German 'hidden champion'. It is a very good model.

A Fast Mask Optimization Method for Extreme Ultraviolet Lithography​

Fast Mask Optimization Method for Extreme Ultraviolet Lithography

Summary
A fast optimization method for pixelated masks in EUV lithography is presented. In the optimization process, an improved pixelated fast thick mask model is used, and the size of the dot pulse on the boundary pixels is set according to the mask pixel size. Based on the double boundary evolution method, in each round of optimization, the optimization variables are adaptively initialized according to the difference between the current photoresist profile and the target pattern profile, and the prior information is used to generate initial individuals and populations, thereby improving the optimization efficiency. The simulation verification is carried out by taking one-dimensional line-space graphics and two-dimensional complex graphics as examples. The results show that the method can effectively improve the simulation accuracy of mask imaging, and the optimization efficiency of the two two-dimensional mask graphics is significantly improved.

Since SMIC can now make 7nm chips with their N+1 technology, does that mean they can make a similar chip as the AMD Ryzen 5600 which is also based on 7nm process? But Intel's i5 11700 chip is based on 14 nm process, but can produce similar performance.
The problem with SMIC 7nm at this time is volume. AFAIK SMIC only has a single fab with this process and it has limited production capacity.

Bro SMIC SN1 FAB in Shanghai is to produce 12nm and 14nm chips with 35,000 wpm capacity, the second Shanghai FAB the SN2 will increase it to 100,000 wpm both FAB will be using ASML DUVL.
SN2 is supposed to be 28nm fab. And if they somehow change it to 7nm or 14nm you would see production decrease from multiple exposures. i.e. it would not be 100,000 wpm but maybe one fourth of that.

I'm still not sure how Huawei has been able to push out a new phone that uses Snapdragon CPU. I thought they are banned.
Huawei is in US entity list. In case you did not notice the whole deal with Huawei ban was never about US national security but continuing the monopolies of Apple, Qualcomm, and Cisco. In particular HiSilicon had to be killed since it was encroaching on Qualcomm sales.

Here is the important part. Back before Huawei was blacklisted from TSMC, Hisilicon expanded so much in 2020 that Qualcomm revenue almost got cut in half! Just think what would happen to Intel/AMD/Qualcomm/Nvidia when China actually can be competitive in this area. Huge loss of revenue for them and TSMC.
Precisely. And so Huawei was put into the entity list and HiSilicon got banned from using Western fabs.

Intel even with their 12th gen CPU is still using 10 nm process. Basically, the very capable Intel engineers have been handicapped by their own fab division. AMD Ryzen 9 CPU is using 7 nm process. Although, their Zen4 CPU will be using 5 nm process by TSMC. As such, SMIC's N+1/N+2 process is sufficient for Phytium/Zhaoxin to achieve competitive CPU design. I'm sure you don't need to be leading edge in desktop computing to satisfy the demand of government or state run enterprise employees.
Zen 4 should be available this year. And SMIC just does not have enough production.

In mainland China, SMIC's scale is far ahead. Similarly, in the quarterly wafer foundry revenue, only 2 manufacturers in mainland China entered the top 10 of the list, SMIC and Hua Hong Semiconductor. Among them, SMIC's revenue is more than three times that of Hua Hong Semiconductor.
This is actually already outdated information. In 1Q22, there were 3 Chinese foundries in top ten: SMIC, HH, and Nexchip.

Starfive RiscV VisionFive2 development board is only 85$ for a 8 GB ram version, also supports nvme for storage (as oppose to rasperry pi emmc/usb only). The posted benchmarks has it similar to the pi4 but will likely lack many software at this stage. Definitly a hackers board as I don't think firefox or chromium has been ported Officially ported though there appears to be other web browser on it

SADP etch process development using PR core for sub 17nm DRAM​

Self-aligned double patterning (SADP) process has become the standard patterning technology for extending the half-pitch resolution beyond current ArF lithography tool's limit. In this paper, we mitigate the compressive stress of ALD SiO2 spacer in SADP etching and solve the SADP spacer pattern collapse problem to minimize the pitch walking deviation. The SADP technology is applied for 17nm of buried word line (bWL) process to meet DRAM scaling requirements.

Good to see Chinese Fabs and Chinese SME providers working on tandem to solve hard problems. That is what create a positive feedback loop.

"On Aug. 12, the DoC’s Bureau of Industry and Security (BIS) established new controls over exports of technology from several countries that the BIS said are essential to U.S. national security.
...
The technologies include two substrates of ultra-wide bandgap semiconductors—gallium oxide and diamond—as well as electronic computer-aided design (ECAD) software for the development of chips with gate-all-around field-effect transistor (GAA FET) structures, according to BIS."

Bro you mean this new FAB under construction using domestic equipment in Free Trade Zone in Lin-Gang Special Area?

Under the agreement, SMIC is partnering with the Pilot Free Trade Zone Lin-Gang Special Area Administration on a joint venture with registered capital of US$5.5 billion. SMIC will control 51 per cent of the venture, while an investment entity designated by the Shanghai municipal government will take 25 per cent. The pair will seek third-party investors for the rest of the stake, the statement said.


The new foundry will have a production capacity of 100,000 12-inch wafers per month. Sanctions are not expected to affect production, as technology related to 28-nm nodes and larger are not restricted by the US.

SMIC said the fab project can help it “meet the growing market and customer needs and promote business development”. The company also plans to use it to expand production and “advance nanotechnology services”.

Shanghai is considered the semiconductor capital of China, with SMIC and Shanghai Huahong Semiconductors, another leading chip maker, calling the city home. The city has also helped nourish many smaller chip design companies in recent years.
Best known for its finance industry, Shanghai has been looking to take a greater role in China’s drive towards technological self-sufficiency. In July, the city unveiled plans to help
