Yes, it's TSMC that is producing the chips, but only a few select companies get enough of a competitive advantage from bleeding edge nodes to be worth the extra cost and lower yields. Intel could do that in theory, but their CPU design is so closely tied to their manufacturing process that they would have to do a substantial redesign in order to do so.
