Chinese semiconductor industry

It's been a super long time since thermal conductivity, band gaps, p-type doping, n-type semiconductor, and other such terminology was of any importance to me, but reading this and the recent news about Apple made me think, why is there not more research into Diamond Like Coatings (DLC) for semiconductor cooling? Apparently Apple already considered it (of course, that's why those guys are paid the big bucks)

Now, if you know, Chinese had recently made some big push into the CVD diamond gemstone business, so much so that it is a big fear of DeBeers

If the yield and process technologies of these Chinese diamond companies have improved so much in the last few years, maybe some exotic cooling apparatus can help push the semiconductor performance as well.

I have several posts on artificial diamond and it's usage in rf filters as well as other areas.

The good people of henan likely will keep creating tech needed for semiconductor industry.

As a whole, diamond will have a place if they can get it's cost down.

Here's an article I published on Micron in anticipation of its earnings call and this Yahoo article:

Hi there, just wondering about your comment on micron's advantage over sk and Samsung. You mentioned it's 1z ddr5 product. Is that the main advanced dram it's producing. I am asking this because I thought it came out with 1b last year? Just curious why their ddr5 is on 1z if they are already shipping 1b drams?

Also, iirc, micron was able to do all it's dram up to 1b without euvs. Are Samsung and sk both using euvs for 1a and 1b?

If so, how has micron being able to do it with arfi scanners? Is it just because etching and disposition are more important for dram production?

But, if the science is real, then why build another research facility. Why go through that expense to verify something that you already verified.

Knowing that the physics of a hypothetical technology works is an entirely different (and much easier) task than actually translating that physics knowledge into a concrete and practical technology. The research centers are for the latter.

As far as my knowledge, these NM values are now just marketing terms, The actual dimension of transistors and pathways for so called 3 NM process from TSMC is like 20NM.

So, what does doing sub 1nm lithography even mean?

Transistors stopped being planar after 28nm came out. With more vertical transistors you need less area and can increase density of the process. After 28nm all numbers you see come out are just indications of relative performance not directly tied to actual dimensions.

Western values at their finest. The west going out of its way to sabotage Huawei for existing and being successful is ‘legitimate protection of western core values’, while Huawei overcoming all the attacks and obstacles the west is throwing at them and doing well is ‘revenge’. Tell me your toxic trash without telling me you are toxic trash.

How is going about one’s own business revenge?

The first instance trial of Zhao Weiguo, the former chairman of Tsinghua Unigroup , for embezzlement, illegal profit-making for relatives and friends, and breach of trust to harm the interests of listed companies has begun.



Xinhua News Agency, Changchun, September 28, 2023. On September 28, 2023, the first instance of the Intermediate People's Court of Jilin City, Jilin Province opened in public to hear the case of Zhao Weiguo, the former chairman of Ziguang Group, of corruption, illegal profit-making for relatives and friends, and breach of trust to damage the interests of listed companies.

The Jilin Municipal People's Procuratorate alleges: From 2018 to 2021, the defendant Zhao Weiguo took advantage of his position as chairman of Ziguang Group to conspire with a specific person Li Luyuan, and the company actually controlled by Li Luyuan purchased at a low price what should have been purchased by Ziguang Group. Tongzhou Business Park project real estate, obtaining real estate premium benefits, and illegally occupying more than 470 million yuan in state-owned assets. From 2014 to 2021, Zhao Weiguo took advantage of his position as chairman of Ziguang Group to hand over the profit-making business of his unit to Li Luyuan and other specific related parties, or to purchase agency management from companies managed by Li Luyuan at prices significantly higher than the market price. services, causing direct economic losses to the country of more than 890 million yuan. In 2019, Zhao Weiguo also instructed directors of the listed companies he actually controlled to lease company projects to companies actually operated by Li Luyuan at prices significantly lower than the market price, causing the listed company to suffer a loss of more than 46.45 million yuan. The procuratorate requested that Zhao Weiguo be held criminally responsible for corruption, illegal profit-making for relatives and friends, and breach of trust and harming the interests of listed companies.

During the trial, the procuratorate presented relevant evidence, and the defendant Zhao Weiguo and his defender conducted cross-examination. The prosecution and defense fully expressed their opinions under the auspices of the court. Zhao Weiguo made a final statement and expressed his guilt and repentance in court.
