Taiwan Semiconductor Manufacturing Co. (TSMC) has completed construction on its second semiconductor fabrication plant in Arizona, further expanding the tech giant's presence in the Phoenix metro area. The new $7 billion facility comes as TSMC's first Arizona plant is already in operation, and the company cites the need for additional manufacturing capacity as the driving force behind the expansion.

Why it matters

TSMC's continued investment in Arizona solidifies the state's position as a growing hub for semiconductor production in the United States. The influx of high-tech manufacturing jobs and economic activity generated by these facilities is a major boost for the local economy.

The details

The new TSMC facility is located near the company's initial $12 billion plant that began operations in 2024. Together, the two Arizona fabs will produce the latest generation of semiconductor chips used in a wide range of electronic devices. TSMC cited the availability of land, skilled workforce, and supportive state and local governments as key factors in its decision to expand in the Phoenix area.

  • TSMC's first Arizona plant began operations in 2024.
  • Construction on the second Arizona fab was completed in April 2026.
