China is not yet able to produce 7 nanometer lithography machine, but long ago, China Shanghai Microelectronics SMEE has produced SSB500\/10A model lithography machine products, and has been delivered, however, at present China can mass production of lithography machine performance is the best 90nm lithography machine, And the Netherlands ASML company's most advanced 5nm lithography machine is still a huge difference, but the manufacturing of advanced lithography machine technology blockade, that we can not learn more advanced lithography machine technology, so that now the domestic need for high-end lithography machine can only rely on imports.
Now, in the field of high-end lithography machine, the Dutch ASML has occupied the leading position, their production of lithography machine occupied about 80% of the market share, it can be said that almost monopolized the high-end optical technology market, at present in the world's most advanced EUV lithography machine is only ASML can produce, and this lithography machine is sold for up to $100 million. Whether it is Intel or TSMC needs 14nm lithography machines, you need to buy from them.
At present, it cannot be manufactured, and the state is organizing relevant enterprises to attack the 14nm process, and 7nm will take a few years to turn
