At present, China's chip industry has been able to design 5nm process and even higher end chips, but subject to capacity constraints can not be large-scale production and application, mainly because we do not have independent research and development of ultra-ultraviolet lithography machine, and the West in order to limit China's semiconductor chip technology, but also limit the export of such high-end lithography machine to our country.
At present, only ASML of the Netherlands has the production capacity of ultra-violet lithographers, and the Wassenaar Agreement, led by the United States and signed by important Western chip technology suppliers, is to block China's technology from the production end of the chip.
With unremitting efforts, the production process independently developed in China has solved the production problem of 28nm process chips, 14nm has achieved initial results, 7nm is also in the adjustment stage, and the future hopes to solve the problem of chip shortage in a short time. In addition, China is now also carrying out research and development of other technical means, such as the third generation of semiconductor chips, optical quantum chips and carbon-based chips, which can achieve cornering overtaking through technological leaps
Production has SMIC, Shilanwei, Shanghai Belling, etc., sealed test has Tongfu, Huatian, Changdian
