TSMC's north Phoenix semiconductor site is the largest greenfield foreign direct investment in US history, with total announced investment reaching $165B for six fabs plus advanced packaging and an R&D center. The third fab broke ground in April 2025 for N2/A16 nodes; the fabs are expected to create about 6,000 direct high-tech jobs and over 20,000 construction jobs.
