these are strange claims.
"reaches the level of TSMC 5nm and has the performance of 8g2" doesn't mean anything.
things that matter are the critical dimensions. And 9000S critical dimensions are so far off N5 that it would be ridiculous to think they can make that jump in 1 improvement.

Could they have chip samples with 140 MMTR/mm2? Sure, but I don't think that's the process for 9100. You'd need a steady production process able to reliably produce 110mm2 die.
Eh. I would probably say unlikely but not ridiculous.

CSIC Special Gases plans to build a project with an annual output of 170 tons of high-purity electronic gases​

CSIC Special Gases issued an announcement stating that according to the company's high-purity electronic special gas development plan, in order to rapidly promote the development of the high-purity electronic gas industry chain, optimize and improve the production capacity layout, and enhance industry competitiveness, CSIC Special Gases plans to build an annual production of 170 tons of high-purity electronic gas project in Feixiang District, Handan City.

Not long ago, China Shipbuilding Special Gases pointed out in an institutional survey that electronic special gas products are mainly stored in specific packaging containers for delivery to customers. The packaging containers include steel cylinders, tube bundle containers, etc. Domestic transportation is mainly by road, while overseas transportation is mainly by sea.

CSSC Special Gas added 1,500 tons/year of tungsten hexafluoride production capacity in 2021. At present, the company's existing tungsten hexafluoride production capacity is 2,230 tons/year. The company's capacity layout is mainly based on the following considerations: First, it is optimistic about the increase in demand for tungsten hexafluoride products due to the improvement of integrated circuit process technology, especially memory chip technology; Second, it takes into account the cost-effectiveness of capital investment in capacity construction.

At the same time, based on the electrolytic fluorination process, CSIC Special Gases has developed and produced a series of trifluoromethanesulfonic acid products, such as lithium bis(trifluoromethanesulfonyl)imide, lithium trifluoromethanesulfonate, trifluoromethanesulfonic acid, trimethylsilyl trifluoromethanesulfonate, trifluoromethanesulfonic anhydride, etc., among which the production capacity of trifluoromethanesulfonic acid is 660 tons, and the maximum production capacity of lithium bis(trifluoromethanesulfonyl)imide is 600 tons.​

The Institute of Microelectronics has made progress in the research of new oxide thin film transistors.​


Oxide random access memory has become the focus of international academia and industry due to its long retention time and advantages in three-dimensional stacking. Among them, In 2 O 3 -based thin film transistors have attracted much attention due to their high mobility. The instability of oxygen in In 2 O 3 directly affects the reliability of the device. To overcome this problem, traditional Ga or Zn doping requires a higher doping concentration, which improves the reliability of the device while reducing the mobility. Therefore, it is necessary to propose a newer oxide semiconductor material system to break through the mobility and reliability constraints of In 2 O 3 -based thin film transistors.

To address this problem, the research team of the High Frequency and High Voltage Center of the Institute of Microelectronics proposed a method of co-sputtering GeO 2 and In 2 O 3 , using the mechanism of GeO 2 actively consuming oxygen vacancies to prepare Ge-doped InGeO thin-film transistors. The researchers characterized the materials and conducted mobility and reliability tests, proving that the material system can greatly improve the reliability of the device without excessively losing the intrinsic mobility of In 2 O 3 , and experimentally verified the consumption effect of GeO 2 on oxygen vacancies. The "Variable Photocurrent Method (VPM)" test system built independently was used to characterize the regulation of In 2 O 3 deep energy level defects by Ge doping. Based on this mechanism, the researchers obtained InGeO thin-film transistors that broke through the constraints of mobility and reliability.
