TW workers have a majority of their compensation in bonuses, so the OT portion is quite small and many do not even bother to ask for it. The overall compensation between a TW and US engineer at TSMC is also significant. Not to mention the lowest paid hourly workers...where in TW they make 2-3X minimum wage, but in the US it's like 1.25X.

Is OT "overtime"? How is it legal not to pay overtime in any US factory? Unless they are salaried (exempt)?

Hahaha. The work culture between TW and the US is night and day - and it isn’t flattering for the US.
