TSMC eyes more Arizona land to grow semiconductor “gigafab” Article originally posted on HERE on October 16, 2025 Taiwan Semiconductor Manufacturing Co. is close to securing additional land in Arizona to create an “independent gigafab cluster,” chairman and CEO CC Wei announced on an earnings call Thursday morning. Why it matters: The new land will allow TSMC to execute its $165 billion vision for Phoenix and cement the Valley as an unequivocal semiconductor The latest: Wei said “strong AI-related demand” is driving TSMC to speed up its Arizona expansion and roll out advanced process technologies sooner. The new piece of land, which he said would be “nearby” the current Phoenix facility, will support TSMC’s current expansion plans and provide more flexibility to respond to expected AI growth, he said. Flashback: The company earlier this year announced it would expand its Arizona footprint to include a total of six fabrication plants, two advanced packaging facilities and a research and development center. When complete, it will constitute a “gigafab cluster,” Wei said.
