At present, China can independently produce technology to improve the lithography mechanism process at about 28nm, which comes from the microelectronics technology in Shanghai. Smic does not have the technology of product research and development of lithography machines, a large number of them are as a contract production role, and now the import of lithography machines is limited.
In 2019, SMIC has already increased the mass production of 14nm processing technology and become China's excellent chip processing, which caused concern in the United States and also caused the target of being banned after Huawei.
At the SEMICON China 2021 exchange, Wu Hanming, academician of the Chinese Academy of Engineering, released a speech, Wu Hanming said that if we do not accelerate the development trend, the difference between China's chip production capacity and that of European and American countries in the future will be amplified to at least equivalent to the production capacity of eight core international companies. Therefore, speed must be increased.
The current situation of Chinese semiconductors depends on insufficient production capacity. Some professionals feel that China's semiconductor development trend rate is too fast, many and complicated, fast and chaotic, but also feel that 14nm is enough. However, Wu Hanming, an academician of the Chinese Academy of Sciences, does not think so, and feels that it should continue to accelerate, especially in the production capacity.
