Sources say AMD will use TSMC's new Arizona fab for the production of new HPC AI chips on the 5nm mode. This move begins an AI chip supply chain in the US, with TSMC and Amkor manufacturing and packaging AMD's high-performance chips. The positive news is a boon for the embattled Arizona fab.

An unconfirmed report says that the US Department of Commerce is making a probe into TSMC whether it's breaking America's sanction on Huawei.

High-ranking U.S. politicians and Morris Chang will attend the TSMC's Fab 21 opening ceremony in Arizona in early December.

TSMC plans to add more American workers as it develops its Fab 21 site in Arizona.

TSMC confirms Arizona Fab 21 is making chips in volume, charges higher prices than Taiwanese fabs.

TSMC is set to build a major semiconductor production hub in the U.S. for $165 billion, but the plans still need to be set.

After a slow, five-year build of its first U.S. fab due to labor and logistical hurdles, TSMC now plans to construct future U.S. facilities in two years, but can its timely access to chipmaking equipment remains an uncertainty.

Doing business with Huawei may be particularly expensive as TSMC is facing a massive fine for 'unknowingly' supplying the blacklisted Chinese company with an AI processor.
