Taiwanese chipmaker TSMC has announced plans to invest a further $100 billion in expanding its manufacturing operations in the United States, on top of previous commitments, as it deepens its American footprint amid growing competition from China's expanding semiconductor industry. The move reflects continued efforts by both TSMC and the US government to reduce reliance on chip production concentrated in Taiwan and to strengthen domestic supply chains for advanced processors used in everything from smartphones to AI systems.

The new pledge builds on TSMC's existing US investment, which already stood at around $65 billion for facilities in Arizona, bringing the company's total committed spending in the country to roughly $165 billion. The expansion is expected to cover additional fabrication plants, advanced packaging facilities and a research and development centre, reinforcing the US as a growing hub for cutting-edge chip manufacturing even as Beijing pushes to accelerate its own domestic chip production capabilities.
