Taiwan Semiconductor Manufacturing Company suspended shipments to China-based chip designer Sophgo after a chip it made was found on a Huawei AI processor, according to two people familiar with the matter.

Sophgo had ordered chips from TSMC that matched the one found on Huawei's Ascend 910B, the people said. Huawei is restricted from buying the technology to protect U.S. national security. Reuters could not determine how the chip ended up on the Huawei product.

Tech research firm TechInsights discovered the TSMC chip on Huawei's Ascend 910B when it took apart the multi-chip processor, a different source told Reuters on Tuesday. Alerted to the finding, about two weeks ago TSMC notified the U.S., the source said.

B-b-but China said all their chips are self made and that sanctions only accelerate their technological progress. You mean they got caught lying through their teeth again?

How do US restrictions factor in here? TSMC is a Taiwanese company with only one operational plant in the US, the majority are in Taiwan, China, and Japan.

Your friend knows a secret recipe for the best chocolate chip cookies. Your mother owns the best ovens in town.

Your friend cuts a deal with your mother to use her oven exclusively. Your mother agrees knowing she’ll get to charge your friend every time they use the ovens.

This is like that. The main value is in the design (recipe). Modern foundry’s are also complex and difficult to operate affordably, but they exist all over the planet. It’s ultimately the partnerships that makes it all possible.

The US is the primary military force protecting Taiwan, by treaty. That's likely why.

And The US is A very big market and TSMC exports a lot of chips into the US.

They could ignore sanctions but that would mean they’d be sanctioned as well. Pretty much every manufacturer and financial institution has to obey laws in multiple jurisdictions if they want to operate within those markets.

There is likely a lot of US tech in that chip. TSMC is just a fab, they don't have a lot of their own technology, they buy thousands of pieces of tech from all over the world to make their chips. A lot of that comes from the US.
