Why can't China just use this for their indigenous EUV development?
Gigaphoton Japan has been frozen out of EUVL development by the US Government and ASML.
Strangely they have continued with Light Source development and are now planning a 300W LPP Light Source with Japanese Government support.
Gigaphoton wont sell its Light Source to China because it fears US Government sanctions.
Maybe they can license their technology to a Chinese company but this is also risky for them.
They could end up being the next US Government victim like Toshiba and Alsthom.
However Gigaphoton also knows that when China produces its own EUVL, it will be too late to enter the China market.
