AMD's main manufacturer is TSMC. They also use other companies AFAIK. Texas Instruments has its own factories in the USA but AFAIK they make other kinds of ICs than the popular ones that TSMC is known for, they do mostly analog and embedded (still important stuff). The sibling post to yours lists other factories. There are definitely other companies.
