A Taiwan-based design-build and engineering firm that serves the semiconductor industry is the latest from the industry to stake a claim to land in Deer Valley, where industry suppliers have clustered.

United Integrated Services Corp., the U.S. subsidiary of a Taiwanese company, bought 29 acres for $41 million in the Mack Innovation Park, located near Seventh Avenue and Pinnacle Peak Road.

The company plans to build a 480,000-square-foot facility on the land, according to brokers from DAUM Commercial Real Estate Services, who represented the company in the purchase.

“As TSMC continues to announce further expansions of its multibillion-dollar campus, it is driving demand from suppliers entering the market and attracting a broader ecosystem of manufacturers, contractors and service providers,” Bob Lundstedt, a broker from DAUM, said in a statement.

Companies have flocked to Arizona to support the $165 billion Taiwan Semiconductor Manufacturing Co. plant, which is being developed in phases. According to data from the Arizona Commerce Authority, since 2020, Arizona has seen 74 semiconductor industry companies expand in the state, representing $214 billion in investment, including TSMC. The announced expansions are projected to create 27,000 new jobs.

In February, Mornstair, a Taiwan-based company that focuses on semiconductor air pollution abatement treatment, also bought land in the Mack Innovation Park. The company, which creates systems to manage chemical waste, bought 52 acres for $59.9 million, according to real estate database Vizzda.

The companies join Sunlit Chemical, which was the first semiconductor industry supplier to buy land in Deer Valley, following the announcement of TSMC coming to Phoenix.

Mack Innovation Park is being developed by Mack Real Estate Group, the developer of some of the major semiconductor industry supplier sites, along with Halo Vista, the 2,300-acre, $7 billion development that surrounds the first phase of TSMC near Loop 303 and Interstate 17.

The company officially broke ground at Halo Vista in March, and the first projects planned in the massive master-planned project will be industrial buildings to accommodate additional semiconductor industry suppliers, Richard Mack, CEO of Mack Real Estate Group, said in March.

At the time, Mack said his team has completed leases and sales totaling about 2 million square feet of space to semiconductor industry suppliers at its existing sites.
