SMIC could have redeployed the immersion lithography machines they already had at their other facilities to make the simpler layers. And used the leading edge machines at their FinFET fab to make the harder layers. The import ban was only applied after the fab expansion shell was complete as well. Who knows how much equipment they got in before the ban.
Then you have the tool vendors moving sales to China ahead of everyone else in deliveries to ensure they could get as much money as possible.
Notice how Singapore is exporting more chip making tools to China than the US with Malaysia right next after the US. That is another loophole. US tool vendors like Applied Materials had fabs in Singapore and Malaysia and were shipping the tools to China anyway, ban or no ban, that landed them into trouble with the US government recently.
The US Department of Commerce is continuing an investigation into Applied Materials Inc.’s shipments to Chinese customers, part of a broader effort to ensure that increasingly strict trade restrictions against the Asian nation are effective.

There was also a massive gap in sanctions where South Korean third parties were reselling machines to China after the ban from the tool vendors. This lasted for quite a while until they clamped down on it. Quite likely South Korean DRAM vendors were dumping immersion DUV equipment in expectation of a move to EUV. Those machines could also have ended up at SMIC.
I would expect SMIC to have those machines and that fab capacity. They probably are in the process of ramping the fab expansion up. As for the spare parts there are third parties which do tool maintenance.
Hearsay and people making things up. TechInsights imaged the SMIC made chips and in their opinion the way they look does not imply low yields at all.
Huawei sold tens of millions of smartphones. Also it is not like SMIC only makes chips for Huawei. For example they make CPUs for Loongson and Phytium with the FinFET process. The Chinese government put a law into place where all government computers must use Chinese chips. They are replacing all their computers with Chinese made ones. Imagine every single government clerk there getting a Chinese PC.
All of those hardware sales are invisible. But they sure show up on Intel and AMD's balance sheets as lost sales in China.
Since when is 10M sales of any semiconductor chip a bad outcome?
It couldn't possibly be that they are scaling back production of the Mate 60 phones because it is a one year old product at this point and they already have enough stock to satisfy existing demand. Right?
