The main uses of the 90nm chip can be used to do power management chips, LCD driver chips, WiFI chips, RF chips, all kinds of digital analog hybrid circuits and so on.
In other words, the 90nm process chip can fully meet the national production needs. There are hundreds of thousands of chips, and it can be said that 70% are produced by mid - and low-end lithography machines.
At present, the lithography machine market is almost monopolized by ASML in the Netherlands, Nikon and Canon in Japan, and Shanghai Microelectronics in China.
