TSMC released two renderings of the office building under construction on the site, a circular, glassy building.  

The project is under construction on 1,129 acres of land near Interstate 17 and Loop 303 that TSMC purchased in December 2020. According to company representatives, the construction is on schedule to be operational in 2024. The project represents the largest foreign direct investment in Arizona's history.

Structural construction of the fabrication facility, called the fab, is nearing completion, and the office building has about half of its glasswork completed. As of June, there are 38 cranes working on the massive site.

Hiring has also been underway, and the company has about 500 Arizona employees undergoing training in Taiwan, where TSMC is headquartered. The company expected to have more than 2,000 employees working at the Arizona plant by 2023.

Spinoff development around the Valley

Arizona's existing semiconductor industry is one of the reasons the chipmaker chose Phoenix for its facility, and the investment from TSMC has drawn suppliers and other semiconductor industry companies to Arizona since TSMC announced its plant.

Sunlit Chemical, a supplier of hydrofluoric acid, which is used in semiconductor production, is building the first phase of its north Phoenix plant in Deer Valley. That plant is scheduled to be operational by 2023, with another phase planned to be open in 2025.
