The life of a lithography machine is not only one or two generations of chips, if the 193nm deep ultraviolet lithography machine can also do 10nm or even 7nm chip production, but the process is difficult to achieve relatively complex, high cost, such as the use of self-aligned four molding technology, you can get a more dense structure, but because the chip level process becomes complex, More masks and materials are needed, so it is not cost-effective to produce 7nm chips with 193nm lithography machines, so EUV lithography machines must be used to this extent.
As the core manufacturing equipment of chip, lithography machine is also one of the most complex precision instruments at present. In fact, the lithography machine can not only be used for chip production, but also for packaging and for LED manufacturing.

At present, China's high-end lithography machines are mainly imported from abroad, and a lithography machine is worth a lot of money, even up to hundreds of millions of dollars.

There is no specific information about the life of the lithography machine on the Internet, so it is temporarily impossible to know.
