Taiwan Semiconductor Manufacturing Company’s expanding footprint in north Phoenix has triggered a cascade of development that extends far beyond its 1,129-acre campus. The chipmaker’s commitment, now totaling $165 billion after a March 2025 announcement added $100 billion to its previous $65 billion investment, has catalyzed the transformation of desert scrubland into what local officials call America’s next major technology corridor.
The most visible manifestation of this transformation is Halo Vista,a $7 billion mixed-use development by Mack Real Estate Group that will encircle TSMC’s facilities. The project encompasses 2,300 acres and includes 12 million square feet of industrial space dubbed “The Forge,” 3.5 million square feet dedicated to the Sonoran Oasis Research and Technology Park, and 500,000 square feet allocated for nearly 9,000 residential units. When fully developed, the project is projected to support 62,000 jobs.
“This is not just a science park, and not just a manufacturing district: It’s a community. It’s a city within a city,” said Richard Mack, CEO of Mack Real Estate Group, describing the development’s scope.
Phoenix officials have embraced the project with notable enthusiasm. Deputy Community and Economic Development Director Nathan Wright characterized the site’s market appeal: “We work with national site selectors weekly and some of the comments that we’ve received are, ‘Hey, this is the best shovel-ready site in the United States.’” The Phoenix City Council approved reimbursement for the developer’s public infrastructure costs in December 2024.
TSMC Arizona‘s gravitational pull on the semiconductor supply chain has proven substantial. Since the company’s Arizona announcement, 39 semiconductor-related companies have relocated to the Phoenix region, creating more than 7,700 jobs and generating over $37 billion in capital investment, according to Chris Camacho, president and CEO of the Greater Phoenix Economic Council.
Among these arrivals, Benchmark Electronics opened a Mesa facility in 2023 to manufacture equipment for semiconductor chip production. “To put it simply, we love being located near a lot of our customers,” explained Ryan Rounkle, vice president of Benchmark’s semiconductor capital equipment sector. Taiwanese semiconductor chemical supplier Sunlit Chemical opened a manufacturing facility in north Phoenix …
