# Taiwan semiconductor security and TSMC global expansion

### TSMC’s overseas fabs and the politics of chip manufacturing

[Taiwan Semiconductor Manufacturing Company](/organizations/taiwan-semiconductor-manufacturing-company) became a focal point of global industrial security because the world's leading chip designers depend heavily on its advanced fabrication capacity in Taiwan. TSMC's overseas investment decisions therefore affect much more than one company's shareholder returns. Disruptions to advanced semiconductor supply can delay products used in data centers, telecommunications, automobiles and defense-related systems. The concentration of capacity across the Taiwan Strait produces a strategic vulnerability for governments that depend on chips while simultaneously giving Taiwan a powerful economic role. Expanding production abroad reduces some geographic risks but introduces high capital expenditure and new labor, supplier and operational challenges.

In 2020 TSMC announced plans for a semiconductor plant in Arizona, signaling a major investment outside Taiwan. By April 2024 the company announced a much larger Arizona commitment, including a third fabrication plant and projected investment above $65 billion. US policymakers promoted domestic semiconductor production through the [CHIPS and Science Act](/facts/chips-and-science-act) passed in August 2022. This was industrial policy motivated partly by supply-chain resilience and national security, not evidence that Taiwan-based manufacturing was already unviable. Semiconductor fabs have long construction and qualification cycles; announcing a project is not the same as delivering commercially qualified output.

On 8 April 2024 TSMC detailed expansion plans as Washington increased support for semiconductor localization. On 15 November 2024 the [US Department of Commerce](/organizations/us-department-of-commerce) announced a multibillion-dollar CHIPS incentives award to TSMC Arizona. Separate company and government accounts described planned capacity, investment and public subsidies. Public funding raises legitimate questions about cost effectiveness and distribution of benefits: subsidized production may strengthen resilience, but taxpayers bear part of the expense while private firms retain intellectual property and commercial returns. A resilient supply chain requires skilled personnel, chemicals, equipment and downstream packaging, not simply more fab buildings.

TSMC's 2024 annual reporting also documented production and investment beyond the United States, including Japan and planned European activity. Taiwan remained central to research and advanced operations even as the company diversified. Expanding to several countries creates redundancy but also increases exposure to multiple regulatory systems, energy costs and export-control decisions. Governments may welcome local manufacturing while competing to attract the same limited pool of specialized engineers and equipment. The benefits of diversification are therefore neither instantaneous nor costless.

The company's geographic concentration is linked to [Taiwan Strait risk](/drivers/taiwan-strait-risk), while licensing restrictions and technology-transfer controls relate to [export-control intensity](/drivers/export-control-intensity). Arizona and other expansions affect [global supply-chain resilience](/drivers/global-supply-chain-resilience), and the CHIPS program illustrates [industrial-policy activism](/drivers/industrial-policy-activism). The central criticism is that governments and corporations spent years tolerating an extraordinary production bottleneck before trying to diversify it. The counterargument is that semiconductor scale economies and accumulated expertise are precisely what make TSMC competitive. Resilience policy must weigh extra capacity, actual operating readiness and the public cost of subsidies against the risk of a catastrophic disruption.
