Missing the point here when talking about nodes and architecture.
Going after EUV lithography underlying technology means China will comprehensively bridge the gap that it lacks fundamental science research capability of industrial power houses like US, Japan and Germany.
Through this effort it will bring China entire industry to a different level.
45nm and 28nm optical lithography is nowhere near the extreme physics limitation and challenges of EUV lithography.it's different world.
I see quite number of Russian physicists from Moscow institutes of physics are hired by Western companies in the EUV industry.
Maybe China and Russia should partner up on this EUV Project. Russians traditionally very strong on physics and most importantly the ability of industrialization of it.
Yes, completely agree.
My original point is that China has a requirement to master every existing technology, in case of sanctions applied by hostile countries.
From the perspective of population, domestic market, R&D spending and R&D personnel - it is feasible for China to do this.
This is inefficient as it would be better not to have to reinvent everything again.
But the end result should be world-class Chinese companies in every industry and producing every component. These should be cheaper and better than their foreign competitors - due to the size of the Chinese domestic market.
But at the same time, China also needs to develop entirely new technologies where there is no existing competition, and which makes existing technologies obsolete.
