This follows the move by TSMC to build a 5nm wafer fab in Phoenix, Arizona with US government support ( TSMC hiring for Arizona wafer fab ). Samsung is also expected to receive significant US government support for its commitment, which is reported to be under negotiation.
Samsung bought land in 2020 and recently applied for planning permission. The plan calls for construction of the shell to start this year with production of wafers to begin in 2023. That would be on a similar time-line or even slightly ahead of that of TSMC.
In May of 2020 that Intel was reported to be in discussions with the US Department of Defense and that TSMC was in discussions with the US Department of Commerce and that Samsung was also being approached about expanding its presence in Austin (see US talks to Intel, TSMC about building local foundry fabs ).
The moves are part of a coordinated initiative to re-inforce chip manufacturing in the US for strategic reasons.
