Well I guess the news of YMTC being able to resume production has now reached Western media.
Also, so much coping at the end here. Samsung & SK have barely started 232 layer production. Most of their production is 128-layer. YMTC expanding 128 layer is perfectly fine. Based on the current rate of AMEC improvement, YMTC will be able to do 232 layer by 2025
I think their anonymous sources timeline of latter in 2024 is a little pessimistic. I would guess start of 2024, but let's wait and see.

Not surprising really. When you play all your cards at once you end up with nothing. Even kids know that.
I think Chinese semiconductor is at the same stage engine development is in 2019. The general feeling is certainly the same.

“0.1um resolution for 7-14nm nodes”? Really?
If china isn't able to get EUV working i wonder whether they could make an improved duvi that uses ~30nm instead of 37nm for 1-pass still using 193nm. I think some companies were researching that ~10yrs ago but gave up when euv started to come out. This would allow them to make sub-10nm cheaper.
I think we should follow the progress of Xuzhou B&C chem & Shanghai Sinyang on this. They are actually working with Chinese fabs on validating their product. I have never heard of this company.
How you measure "far away"? Market share? That means how much is going to be lost to the competition. Technology? What is the magical technology then. The 1,000,000 line of code of KLA tools? That is just math and most of the code is just auto generated anyways. What is the alien material that only KLA can get?
