Havok just debunked this post，so it's fake news
秦声楚舞：
这个消息靠谱吗？
Havok：上微给ICRD发子系统? ICRD是要自己造光刻机么？
秦声楚舞：Is this news reliable?
Havok：Shangwei issued a subsystem to ICRD?does ICRD want to build its own lithography machine?
Plus as people already said in that Zhihu thread，this news claims that Huawei bought Nikon dry-type lithography machines，and somehow managed to convert it to immersive-type machines. It's just not feasible in practise.
Is possible to convert dry machines into immersions ones, I think the first production immersion machines where dry to immersion conversions, you wont get 1.35 NA because current immersion machines have dedicated projection lens systems for that but the NA will be above 1. In fact the first plan of SMEE was to adapt an immersion system to their dry 90nm Arf Scanners to allow the system to pattern to 65nm.
That part that I still don't getting is the part of adapting dual wafer stage to a single wafer stage machine. I don't know but dual wafer stages have different vibration mechanics than single wafer stages but guess they could add some adaptations to get it to work.
According to your logic, China need not spend too much on R&D, and struggling how to make the product not absurdly expensive.
If we do like that then we never catch up, we can catch up because we are willing to spend more money. Just an example, how much did SMIC pay Dr. Liang, and how much Samsung paid him?
Money must be spent a lot to catch up.
And Private companies do not want to lose, that is why government must lend its hand to solve the problem.

Also, the ICRD did was involve in the development of subsystems for the lithography machine as this patent point out.
What? I don't think you understood what I said. I'm saying China isn't paying money to "catch up" in the sense of being able to make 3nm chips. They already made those. Hell if your talking about non-mass produced stuff China's already made them with EUV. Thus, in the sense of can China make low nm chips, the answer was yes even before the whole trade war. If that's all China was going for, then yes, they could just stop right now.
What China can't do is make reasonably priced, high yield versions of those chips. The problem with this is, just throwing money at the problem doesn't solve a damn thing. All things need to be accounted for. This is why Xi is calling for a whole of society solution.
I think you must reread my post, where in my post did I write about a 3 nm chip ?
It is in your imagination, then you said I wrote that
