This plant was the foundation that the CHIPS act was built upon. The Secretary of State had to secure an agreement with TSMC to build this fab before the bills could be drafted, as a lot of the recipients of the funding are suppliers for this plant.
It is completely truthful to assert that this is the result of the CHIPS act. Congress agreed to introduce the bills as a result of TSMC's agreement to build the fab in Arizona. If you have to avoid giving Biden credit, then you can point out that it was Trump's SoS who negotiated this original agreement.
