Arizona Lands $100 Billion TSMC Expansion with 5 New Chip Facilities

Taiwan Semiconductor Manufacturing Co. (TSMC) is investing another $100 billion in the United States, with the bulk of the investment going toward new and existing sites in Arizona, President Donald Trump announced Monday. The new investment brings TSMC’s total U.S. commitment to $165 billion, cementing Arizona’s role as a major hub for semiconductor manufacturing.

TSMC, the world’s largest semiconductor manufacturer, supplies chips for companies like Apple, Nvidia, and Intel. The company had already pledged $65 billion for its Arizona facilities, supported in part by the CHIPS and Science Act, which provided $6.6 billion in subsidies. TSMC’s first factory in Phoenix has already begun mass production of its advanced 4-nanometer chips.

TSMC CEO C.C. Wei said the newly announced $100 billion will fund three additional manufacturing plants and two packaging facilities in Arizona. Trump called the move a “tremendous win for the U.S. economy and national security.”

“Semiconductors are the backbone of the 21st century economy. And really, without the semiconductors, there is no economy,” Trump said. “We must be able to build the chips we need here in American factories.”

Arizona leaders welcomed the news, emphasizing the economic ripple effect the investment will have on the state. Phoenix Mayor Kate Gallego said the expansion solidifies Arizona’s reputation as a leader in semiconductor manufacturing while creating thousands of high-tech jobs.

“This is a major win for Phoenix and for American workers,” Gallego said. “TSMC’s investment will boost innovation, strengthen domestic supply chains, and drive economic growth across the region.”

Danny Seiden, President of the Arizona Chamber of Commerce, not that the investment will create tens of thousands of jobs and spur demand for housing, restaurants, and other local businesses.

“This is huge news for Arizona,” Seiden said. “It’s not just about the jobs at TSMC — this will boost our entire economy.”
