Biden visits Arizona semiconductor plant in latest celebration of the CHIPS Act

In the four months since he signed the Chips and Science Act of 2022 into law, President Biden has made a habit of visiting semiconductor plants — or plants to be — to tout the effects of the law.

Recent stops have included the groundbreaking of an Intel (INTC) facility in Ohio and a Micron (MU) plant in upstate New York. On Tuesday, the Taiwan Semiconductor Manufacturing Company (TSMC) hosted the president as it unveiled plans for an upgrade of its capabilities in Phoenix and announced plans to build a second facility nearby.

"What we are doing here in Arizona matters across the country and around the world," President Biden added when he took the stage to tout the overall investment of approximately $40 billion, which the White House called the largest foreign direct investment in the state's history.

"We're building a better America."

The event was a high-profile affair with figures from TSMC founder Morris Chang in attendance alongside Apple (AAPL) CEO Tim Cook, the CEOs of Micron and NVIDIA (NVDA), and a bevy of political officials from Commerce Secretary Gina Raimondo to Katie Hobbs, Arizona’s incoming governor.

"This state of the art facility behind us is testimony that TSMC is taking a giant step forward to help build a vibrant semiconductor ecosystem in the United States," TSMC Chairman Dr. Mark Liu said Tuesday while introducing President Biden, adding his thanks to Biden personally for the U.S. government's “continual collaboration that has brought us here.”

At the event, Biden as well as the other dignitaries in attendance discussed the two announcements, including a new facility in the works, also in Arizona, that will produce advanced 3 nanometer chips by 2026. The company also plans to upgrade its current facility to produce 4 nanometer chips by 2024.

A note of caution came from CFRA Research Senior Equity Analyst Angelo Zino, who joined Yahoo Finance Live Tuesday. Zino said much of this new capacity could end up being "trailing edge technology" and that reliance on Taiwan will continue "longer than many want to," because these facilities take years to come online amid ongoing tensions between Taiwan and China.

Biden notably didn’t visit Arizona during the recent campaign season, even while visiting neighboring states. Democrats like Governor-elect Hobbs and Sen. Mark Kelly (D-AZ) won anyway and the trip is also being criticized by Republicans for not including a visit to the border with Mexico.

As he departed for Phoenix on Tuesday morning, Biden spoke with reporters and pushed back on the criticism, saying he wasn't visiting the border "because there are more important things going on."
