From the article:

> The U.S. accounts for 60% of TSMC's sales, but the company operates only its subsidiary WaferTech there, producing chips for mature technologies.

In this case[1], "mature technologies" appears to mean downto 160nm tech node...essentially irrelevant with respect to FPGAs.

Wafertech has 0.16-micron and above processes.

The US wants TSMC's latest GIGAFAB's.

the article mentioned that, but you aren't having stuff like n7 or n10 nodes being done in US, which is what Washington presumably wants
