The anti-radiation chip of the Institute of Microelectronics helps the construction and operation of the Chinese space station​

On November 3 , 2022 , the Mengtian experimental module of the space station successfully completed its relocation, marking the official completion of the basic configuration of the " T " character of the Chinese space station. On November 12 , the Tianzhou-5 cargo spacecraft quickly rendezvoused and docked with the Tianhe core module of the space station, and the space station entered the long-term on-orbit operation stage. During the construction and future operation of the space station, microelectronics has provided strong support in terms of radiation-resistant core chips. Eight radiation-resistant chips , including KW064 , KW8Q512K8 , KW54HCS164 , KWJCTRCS7426 , and KWRCS7382 , developed by the Key Laboratory of Radiation -resistant Device Technology The application in the core payload of the space station helps the construction and operation of the space station.
　　The Institute of Microelectronics is the backbone R&D institution of radiation-resistant chips in China. The key laboratory of radiation-resistant device technology has been engaged in the research of radiation-resistant hardening technology for a long time . Developed a variety of anti-radiation 0.35-0.13 micron SOI CMOS technology based on independent intellectual property rights , pedigree anti-radiation chip products, the anti-radiation index has reached the international advanced level, and related achievements have won 2 provincial and ministerial awards .

SMEE Lithography machines are an overkill for this kind of applications. Anything else more advanced has been fabricated in the past few years with low volume EUV machines and low volume Arf immersion machines.

Significant progress has been made in the direction of ultra-radiation-resistant carbon nanotube devices and circuits in microelectronics​


The new generation of spacecraft puts forward higher requirements on the performance and radiation resistance of aerospace chips. Carbon nanotube devices have high gate control efficiency and strong driving ability. They are one of the semiconductor technologies with the most development potential in the post-Moore era, and they also have strong space application prospects.
　　The Key Laboratory of Anti-irradiation Device Technology of the Institute of Microelectronics cooperated with Professor Zhang Zhiyong of Peking University and Associate Researcher Chen Rui of the Space Center of the Chinese Academy of Sciences to develop carbon nanotube transistors and SRAMs based on local bottom gates, and systematically studied carbon nanotubes. Comprehensive radiation resistance of devices and circuits (Figure 1 ). Studies have shown that localized bottom-gate carbon nanotube transistors and SRAMs can still withstand a total ionizing dose of 2 Mrad ( Si ) and 10 4 MeV · cm 2 /mg equivalent laser single particle irradiation, its comprehensive radiation resistance is four times better than that of silicon-based devices (Figure 2 ). The above results prove that carbon nanotube devices and circuits have super radiation resistance, which opens up an important technical path for the development of next-generation aerospace chips.
　　The research was supported by the National Natural Science Foundation of China. Recently, the research results were published in the internationally renowned journal "Small" under the title "Ultra-Strong Comprehensive Radiation Effect Tolerance in Carbon Nanotube Electronics" ( DOI : 10.1002/smll.202204537 ). Dr. Lu Peng from the Key Laboratory of Radiation Resistant Device Technology is the co-first author of the paper, and Researcher Li Bo is the co-corresponding author of the paper.

I wanted to know how it would run games on linux with wine. That would be quite interesting.

Songshan Lake Materials Laboratory

Profiler, also known as probe-type surface profiler, is used to measure the profile of the sample surface from micron to nanometer scale. Indispensable key measuring equipment in the field. For a long time, this type of instrument has been monopolized by three manufacturers, Bruke, KLA, and Kosaka, and there is no domestic manufacturer that can provide similar products. Until June 2022, the self-developed procedural instrument developed by the precision instrument R&D team of Songshan Lake Materials Laboratory was shipped and delivered, achieving a zero breakthrough in the localized procedural instrument!? Zero breakthrough! The precision instrument team successfully developed the localized procedural instrument

From what I got from the video the performance is kind of disappointing. Like 1/3rd the performance in games as the RTX 3060 some said this would go against. But the fill rate and FP compute seems to be slightly better than RTX 3060. A lot better than RTX 3060 with single textured fillrate. So this is either lack of optimized drivers or lack of some feature in hardware which bottlenecks the games.
