TSMC's big Gigafabs are 100,000 per month and none of them are going to be build outside Taiwan. Arizona fab is 20,000 wafers per month Megafab where the capacity might be doubled eventually.<p>It seems to me that these Megafabs in US, Germany elsewhere exist to provide minimal strategic security of supply in case there is a conflict between Taiwan and China. The economy will collapse, but you avoid the worst with 20% domestic manufacturing goal is enough in crisis to provide essentials.
