China can produce 28nm DUV lithography machines with 100% Chinese suppliers as of last year. There are very few countries in this world that can produce their own DUV lithography machines in this world. With every passing year, China will be producing more advanced DUV lithography machines, which means they will not have to buy Japanese and Dutch lithography machines in the future. Tsinghua university is developing a SSMB EUV light source, and this will enable China to produce 3 nm, and 5 nm chips in the future. It is actually a EUV lithography cannon.
China has 14 nm lithography machines, and they can technically produce 7nm chips by using multi patterning. The yields are lower, but they can produce 7nm chips by using this method.
China can produce 14 nm chips with their 28nm DUV lithography machines with multi patterning. As of today, China can produce, automotive chips, RISC processors for smartphones/mobile devices, chips for military equipment, X86 chips, 5G chips, etc.
China produces 4 million engineers and scientists every single year while the US produces about 400,000/year. Producing something like a lithography machine is difficult, but if you have many scientists and engineers in the fields of optics, chemistry, electronics, electrical engineering, lasers, etc it will be possible to achieve those goals in the future.
The outcome of all of this is, US semiconductor companies losing market share in the biggest chip market in the world. This will mean, US semiconductor companies will have less money to spend on R&D to produce better chips in the future. At the same time, Chinese semiconductor companies will make more money, and spend more of it on R&D producing better and better chips. Like Kevin said, those Chinese semiconductor chips will be selling their chips in the global market which will take more market share from US companies.
