Rep. Abe Hamadeh (R-AZ08) praised a new $100 billion investment by Taiwan Semiconductor Manufacturing Company (TSMC) that will add four advanced semiconductor fabrication plants at the company’s north Phoenix campus and raise its total planned Arizona investment to $265 billion.
The White House and Department of Commerce announced the expansion Thursday, saying it resulted from a trade and investment agreement reached between the United States and Taiwan earlier this year.
The four additional facilities will bring TSMC’s planned American footprint to 12 advanced semiconductor manufacturing and packaging facilities, all located in Arizona. The Arizona Commerce Authority said the expanded Phoenix campus is now expected to include 10 semiconductor fabrication plants, two advanced packaging facilities, and a research and development center.
Hamadeh, whose Eighth Congressional District includes the TSMC campus, praised President Donald Trump’s manufacturing agenda and said the project would create new employment opportunities for residents of the West Valley.
“These targeted investments in Arizona’s Eighth Congressional District aren’t just welcome — they’re exactly the kind of bold, America-First moves our district needs,” Hamadeh said in a Thursday announcement.
“My constituents are ready to work, ready to build, and hungry for the high-paying jobs these projects will deliver right here in the Grand Canyon State,” he added.
Hamadeh said he believes veterans should receive priority for employment opportunities connected to the expansion. His office has made economic development and workforce growth central parts of what it describes as a “Peace through Prosperity” agenda.
Commerce Secretary Howard Lutnick said the investment would create tens of thousands of American jobs. The Commerce Department said the expansion is expected to generate significant construction and high-technology employment while increasing domestic production of advanced semiconductors.
TSMC Chairman and CEO C.C. Wei said the expansion is intended to meet growing demand from the company’s American customers and strengthen the domestic semiconductor supply chain. The latest commitment follows a $100 billion expansion announced in March 2025, which raised TSMC’s planned Arizona investment from $65 billion to $165 billion. That expansion added three fabrication plants, two advanced packaging facilities, and an R&D center to the company’s original plans.
TSMC initially announced a $12 billion Phoenix facility in 2020. The company expanded the project to $40 billion in 2022 with plans for a second fabrication plant and increased the commitment to more than $65 billion in 2024 by adding a third plant. The two initial facilities were projected to create approximately 4,500 direct TSMC jobs, while the first three were projected to create 6,000 direct manufacturing jobs and more than 20,000 construction jobs.
TSMC currently employs more than 3,500 people in Arizona. The company’s first Arizona fabrication plant began high-volume production using its N4 manufacturing process during the fourth quarter of 2024. Construction of the second plant’s main structure was completed in 2025, with production using N3 technology targeted for the second half of 2027.
Construction of the second plant’s main structure was completed in 2025, with production using N3 technology targeted for the second half of 2027.
The company broke ground on its third plant in April 2025. That facility is scheduled to manufacture semiconductors using TSMC’s N2 and A16 process technologies, with production targeted to begin by the end of the decade. Before the newest expansion, the Commerce Department finalized an award of up to $6.6 billion in direct funding and made up to $5 billion in loans available under the federal CHIPS incentive program to support TSMC’s first three Arizona plants. The facilities are intended to produce some of the world’s most advanced semiconductors and provide American technology companies with access to domestically manufactured chips.
Hamadeh’s office said the expansion would help establish Arizona’s Eighth Congressional District as the “Silicon Desert” and strengthen the country’s position in semiconductor and artificial intelligence manufacturing.
“This major investment is further proof that the Trump Administration is laser-focused on restoring American manufacturing dominance,” Hamadeh said.
