Taiwan Semiconductor Manufacturing Co. is considering a new Texas campus that could add tens of billions of dollars to its multiyear U.S. expansion. The project would include multiple fabs (semiconductor manufacturing plants), each costing at least $20 billion, although discussions remain at an early stage. TSMC has already committed $265 billion to an Arizona site, where it is developing several plants. North America generated more than 75% of the company’s wafer revenue so far this year, while orders from Nvidia Corp. and Advanced Micro Devices Inc. have increased pressure on capacity amid the artificial-intelligence boom. The Texas plan depends on extending an advanced-manufacturing tax credit created under former president Joe Biden’s 2022 Chips Act and increased to 35% last year. TSMC is also discussing possible investment with Singaporean officials, while continuing to develop facilities in Japan and Germany. The company says its overseas expansion responds to customer demand and depends on local-government support, but Taiwanese officials and executives maintain that the most advanced research and development will remain at home.
