> What other companies also do this? Are Nvidia, and AMD on this list?

No and no. IBM (for Power products) and arguably Samsung (for their mobile chips) are effectively the only ones left on their own leading edge nodes. Everyone else uses TSMC, GloFo, or SMIC.




IBM doesn't have its own fabs anymore -- they gave them to GlobalFoundries in 2015, along with $1.5B.


I would have taken the fabs for half of that! :-)
