America's Semiconductor HQ
For more than 70 years, Arizona has stood at the forefront of semiconductor design, development and production, starting with Motorola in the 1940s followed by the opening of Intel’s first fab in the state in 1979. Today, Arizona leads the nation in semiconductor investment, supplier expansions and jobs. Since 2020, Arizona has won more than 70 semiconductor expansions, representing over $319 billion in capital investment – cementing Arizona as the home of America's semiconductor HQ.

Arizona is home to one of the most advanced semiconductor ecosystems in the world. The Arizona Semiconductor Asset Map makes it easy to discover businesses across the state, connect with workforce training partners and universities, and explore the state's innovative R&D facilities.
Governor Katie Hobbs announced the launch of the Future48 Workforce Accelerator at GateWay Community College to train Arizonans for the growing semiconductor industry. The Accelerator offers hands-on training and support services, including child care and transportation. This accelerator is part of a larger initiative to prepare Arizona’s workforce for advanced manufacturing roles, in collaboration with local community colleges and industry leaders.
Intel and Governor Hobbs launched the company’s first U.S. registered apprenticeship program for manufacturing facility technicians in collaboration with the Arizona Commerce Authority (ACA), SEMI Foundation, Fresh Start Women’s Foundation, Maricopa Community Colleges, and the Phoenix Business and Workforce Development Board.
Amidst heightened global demand and a steadily shrinking share of the world’s most advanced microchip factories, the Arizona Commerce Authority joined semiconductor industry leaders and stakeholders to launch the National Semiconductor Economic Roadmap (NSER). The industry-led effort aims to boost U.S. semiconductor competitiveness through a focus on the workforce, supply chain and infrastructure to support semiconductor research and development, design, manufacturing, and end-applications.
In March 2025, President Trump and Taiwan Semiconductor Manufacturing Corporation (TSMC) Chairman and CEO C.C. Wei announced a historic expansion of TSMC's advanced semiconductor operations in Arizona. TSMC announcement will invest at least an additional $100 billion to build three more semiconductor fabs in Arizona as well as two advanced packaging facilities and a major R&D Center. In July 2026 TSMC announced an additional expansion of $100 billion investment to build four additional fabs. The announcement brings TSMC’s total investment in Arizona to $265 billion — representing 10 fabs, 2 advanced packaging facilities, and a R&D center, all supporting thousands of high‑tech jobs.
TSMC's historic announcement cements Arizona as the epicenter of advanced chip manufacturing and innovation in America. With the country's most advanced chip-making processes, world class university partners, and a robust and growing talent pipeline, Arizona is powering the groundbreaking technologies of the future like AI. I'm grateful to President Trump, TSMC, and all our partners for making this historic day possible.
