TSMC building outside of Taiwan is a big deal these days: https://en.wikipedia.org/wiki/TSMC#Arizona https://en.wikipedia.org/wiki/TSMC#Washington https://en.wikipedia.org/wiki/TSMC#Japan https://en.wikipedia.org/wiki/TSMC#Germany

From the article:

  "about 30 percent of our 2-nanometer and more advanced capacity will be located in Arizona"

.. so it's interesting that they are moving forward with domestic 1.4nm given the geopolitical climate.
