Chinese semiconductor industry

and US inflation will be skyrocketed, this have not count the effect of money printing
just a numbers game, plus Chinese share of semiconductor production is small anyways, non-existence for leading edge ones.
What about the rest of the world? If you add what will be used in and by China, with what will be used by The European Union and the rest of the world, I don't think there is much left for the US to consume and therefore sustain the billions it is investing.

One must not forget that a considerable amount of electronics is manufactured or at least assembled in China.

Something does not seem to add up here!
The American market is the biggest or the second biggest market in the world. Companies aren’t gonna set up two production lines: one for the US market and another one for the rest of the world. With China’s small share of semiconductor production, companies can afford to avoid Chinese made chips.

Hopefully cetc can be more aggressive and its 35nm NA1.35 can go to 14nm as well like asml

smee which makes 28nm only and plans to deliver maybe 3 samples this year and mass production begins 2022 and 2023. 14nm won't comes out till 2024.This is according to the big shrimp havok

Dry dual stages are more ready, goes to 65nm . Production is currently.

I wonder how it going with Huawei 40nm which uses that machine
So if the timeline is right
28nm: 2021
28nm (to scale): 2022/2023
14nm: 2024
7nm: 2025 (with multi-patterning)
EUV: 2025 (as well)?

2021. 3 smee 28nm samples
2022 to 2023 28nm production around 15 to 20 sets.
2024 smee 14nm projected

7nm nothing heard on that yet.

We also don't know what cetc capable on its 35nm duv.

Euv 2025 maybe

By 2025 China should established fully 28nm Indeginous, the country can function without any western tech.

It's one of the key elements needed for operation Taiwan Unification. China may got fully sanctioned and get kick out of dollar system.


28nm and digital yuan ! The baseline.

The shipping costs for semiconductors are basically irrelevant. Just think about the size, weight, and cost of a chip. You could even send them by airplane and it wouldn't matter. This is different for larger form factor and lower cost things like boards and other PCBs which is where China dominates.

Once US steals TSMC tech to US side , it can ditch taiwan When China starts operation Taiwan unification.

In exchange US forces will use its Marines to land and take over SCS man made islands.

China needs 2 carrier strike groups 003 and 004 to preempt US from taking that route.

China will get fully sanctioned by the west and get kicked out of dollar system afterward

Target should be fully indigenized 14nm production lines by 2025; 7nm in risk production by then.

SMIC will have their N2 node in scale production long before 2025, albeit not necessarily on fully-indigenous production line.

Need to pursue multiple parallel tracks, which can then merge their experiences and expertise down the road.

A synchrotron light source? That seems kind of impractical because the machine will be huge.
You will need to design the facility around the synchrotron.
I can see it being used for either research or even military or government production but for commercial use seems kind of complex.
To expand on this, on the surface, it seems impractical but why would the recommendation be for industrialization? We know the main advantages of SSMB EUV would be much higher power than LPP EUV along with narrow spectrum, continuous wave radiation that is almost laser like.

This is a thought experiment but if I were to take a wild guess, I would say they are researching a next generation EUV lithography machine with source power approaching or exceeding 1000 watts and because such continuous wave radiation does so much less damage to the optics, that such EUV light could be split into multiple exposure chambers similar to how white light splits from a prism except the purpose would be to have more exposure zones for increased throughput. In this scenario, even a huge synchrotron sized light source would make sense if it were the equivalent of 5-20 ASML EUV lithographs. Note that continuous wave radiation would provide far more efficient EUV delivery to the wafer so source power from say 250w from SSMB EUV would be far superior to 250w source power from LPP EUV. This is all speculation of course.

The artificial island is already and unsinkable super giant carrier.

This raise my interest on learning optical physics, what kind of course or major that dwelled this knowledge?
