This news should not be true at present, at present, China's lithography machine can only complete the mass production of 28nm chips, is conquering the 14nm process, and 7nm and below are still completely unable to hit, let alone 3nm.
According to the analysis of China's lithography machine technology, and ASML's most advanced process lithography machine there is about a 10-year gap, therefore, there is currently no ability to produce advanced process chips, in the current increase in investment, optimistic estimates that after 5 years to achieve 7nm process, this is still possible.
The domestic 3nm lithography machine is fake, and now China's scientific and technological strength can not manufacture 3nm lithography machines. Now the world's top lithography machine manufacturing company, the Netherlands Asmail, can only manufacture 5nm lithography machine!
The best lithographic machine manufacturing company in China is the Microelectronics Factory in Shanghai. But the most advanced lithography machine in Shanghai Microelectronics Factory is only 28nm!
