Moore Threads is one of the founding 24 members of China Mobile's metaverse industry alliance. The virtual world likely to require a lot of computational power for graphics rendering, simulation, AIGC and such. Looks like Huawei & MT are the main hardware suppliers of this. Although, I wouldn't be surprised if China Mobile is also using a lot of Nvidia GPUs

This to me seems like an area where American tech companies just haven't been interested in. I wonder if demand for this is higher in Asia or why the interest is so much greater for this among Chinese tech companies

China Mobile looking to increase computation power from 8 to 20 EFLOPS by 2025


Also, I was looking up other Chinese AI companies to see how much domestic GPUs they use.

From here last year, Sensetime's Lingang data center was using 5 domestic GPUs for 15% of its computational power there. A lof of things have changed in the past year. But one would imagine if Nvidia GPUs are banned, there is a pretty large market for domestic chipmakers to expand into
上海临港新一代人工智能计算中心AIDC于2022年1月24日正式启用，基于技术突破及芯片性能提升，临港AIDC峰值算力预计将比原设计峰值扩大33%达5 exaFLOPS；已上线算力达1.745exaFLOPS；已实现5种国产芯片适配，国产化算力规模占已上线规模的15%。

CETC achieves full coverage of 28nm technology for domestic ion implanters​

A reporter from Xinhua News Agency learned from China Electronics Technology Group Co., Ltd. on June 29 that the group's China Electronics Technology Electronic Equipment Group Co., Ltd. (referred to as Electronic Technology Equipment) has achieved full coverage of the 28-nanometer process of domestic ion implanters, which effectively guarantees my country's integration. Industrial safety of the circuit manufacturing industry in the mature process field.

Ion implanters are key equipment in chip manufacturing. In the chip manufacturing process, it is necessary to dope different kinds of elements to change the electrical properties of the material in a predetermined way. These elements are accelerated to a predetermined energy in the form of charged ions and implanted into a specific semiconductor material. The ion implanter performs this doping. Miscellaneous chip manufacturing equipment.

At present, 28nm is the mature process with the widest coverage in the chip application field. According to reports, Dianke Equipment has continuously made breakthroughs in the core technologies of key modules such as optical path, control, and software, and has formed a product structure of a full range of ion implanters including medium beam current, large beam current, high energy, and third-generation semiconductors. Coverage, effectively guarantee the production and manufacture of domestic chips.

It is understood that as the earliest enterprise engaged in the development and industrialization of ion implantation equipment in China, Dianke Equipment has a complete development system from product design to mass production application, and its products cover logic devices, storage devices, power devices, sensors and other process devices. Hundreds of equipment are widely used in the advanced production lines of major integrated circuits in China, with a cumulative tape-out of 20 million pieces, which has effectively improved the resilience and security level of my country's industrial chain supply chain.

No idea. My uneducated guess is that ion implanters are used in different steps in the process and each has different requirements. Now the domestic implanters can meet all the requirements for 28nm. But I am not in this field.

Waiting for our in house experts to explain.

Ion implanters are classified by their current and their energy. So I think they mean that they can manage the doping using an array of elements in the 28nm process, some elements require high energy while others the doping has to be more docile.

Apart that they have ion implanters for photovoltaic and third gen semiconductors.

Pure Technology: We have repeated orders for wet cleaning equipment in all 28nm process steps​


1272838652525.55251274298693313.0396.png


According to news from Jiwei.com, recently, some investors asked a question on the investor interaction platform: Your company said that 212 million of the new orders signed in the first quarter of 2.1 billion were process equipment. Does it mean cleaning equipment? Your company's friend Shengmei said that the company's cleaning equipment has covered 90-95% of the cleaning process, and said that new customers accounted for a large proportion of this year's sales. What is the coverage level of your company's cleaning equipment and the trend of new orders for cleaning equipment in the semiconductor industry this year?

Zhipure Technology (603690.SH) stated on the investor interaction platform on June 29 that the company's process equipment covers various types of equipment in the semiconductor field, mainly wet cleaning equipment. The company's wet cleaning equipment has passed verification in all process segments of 28nm and has repeated orders. The company also took the lead in breaking through the monolithic SPM equipment that was originally monopolized by foreign countries.

As of press time, the market value of Zhichun Technology is 13.077 billion yuan, and the stock price is 33.90 yuan per share, an increase of 0.86% from the closing price of the previous day.

China’s semiconductor industry can’t quit German optics​

"When it comes to the optical systems in its lithography machines, SMEE does not tend to source from foreign firms, according to its website. Instead it uses systems from Chinese optics companies like UP Optotech, Focuslight Technologies, and MLOptic Corp. However, recent documents from these firms in turn showed heavy procurements from German and American suppliers."
UP Optotech’s 2021 annual report revealed that the firm’s top supplier wasn’t Chinese, but in fact the German application-specific integrated circuit company iC-Haus. That year, 11.49% of the company’s procurements came from iC-Haus.

So since when is an ASIC "German optics"? Dumbass article. ASICs are chips. And in the case of this German company they seem to make ASICs for sensors and/or mechanical control.

gadgetcool5 said:
There's plenty more in that article (showing SMEE's suppliers reliant on German, Japanese and American glass polarizers, precision motors, resins, etc. ). So before developing its semiconductor industry, China must develop its lithography industry, and before developing its lithography industry, China must develop its optics, precision positioning instruments, and materials science industries. Interesting reading.

There is no before. Everything must be developed simultaneously. And is being developed simultaneously.
I fully expect the market for things like lenses and materials to continue increasing in China. China already is probably the largest maker of security cameras, and they are also heading towards being the largest maker of cameras for both drones, and smartphones. Not quite the same thing, but China's optics technology has been improving, heck everything has been improving over the past decade.
