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.
Power to produce 14 nanometer chips.
The highest domestic energy production process chip is currently 14 nanometers. At present, the strongest chip processing capacity in China is SMIC, and its n1 technology can enable it to process 14nm chips with duv lithography machines, or even lower processes. For example, the Honor play4t equipped with Kirin 710A is a 14-nanometer chip manufactured by SMIC. At the same time, SMIC can also manufacture chips closer to 7 nanometers, and it is still improving the yield.
