There are mobile phone chip lithography machines in China.
There are not only mobile phone chip lithography machines in China, but also pure domestic lithography machines. At present, only four companies in the world have the ability to manufacture lithography machines, the only high-end Dutch Asmer euv lithography machine, Japan Nikon and Canon duv lithography machine, China Shanghai Microelectronics duv lithography machine. Shanghai Microelectronics only did the low-end 90 nm lithography machine last year, and the 28 nm mid-end duv lithography machine passed the technical inspection and certification at the end of last year, and it should be produced this year.
At present, there is no independent mobile phone chip lithography machine in China, and only high-end lithography machines can be purchased from the Dutch asml company.
But the domestic has a low-end wide mouth machine, about ten nm above, but can not produce mobile phone chips, the current center international it can produce 14 nm Huawei Kirin 710a processor, although the performance of the processor is not TSMC's 14 nm process, but basically can be used for Huawei's low-end mobile phone above.
