TSMC (Taiwan Semiconductor Manufacturing Company) is the contract chipmaker that physically manufactures most of the world’s most advanced processors, including the GPUs and AI accelerators the modern AI industry depends on. By TSMC’s own published company profile, it was founded in 1987 as the world’s first dedicated semiconductor foundry: a company that does not design or sell its own chips, but manufactures the designs of other companies.
A fab, short for fabrication plant, is the factory where chips are made. Inside it, designs are printed onto silicon wafers layer by layer in a process of extraordinary precision and cost, using lithography machines (the most advanced supplied by ASML) to pattern features measured in nanometers. Building and equipping a leading-edge fab costs many billions of dollars and years of work, which is why most chip designers do not own fabs at all. Companies like NVIDIA, Apple, and AMD design chips and hand the designs to a foundry to build. That foundry, at the leading edge, is overwhelmingly TSMC.
This makes TSMC a chokepoint in the AI supply chain. The most powerful AI chips cannot simply be made anywhere; they require a foundry with the most advanced process nodes, and TSMC’s leadership in those nodes means a large share of cutting-edge AI silicon flows through its facilities. That position sits at the center of the chip-geopolitics story, alongside U.S. export controls that restrict which advanced chips and tools can be sold to whom, and ASML’s monopoly on the lithography machines that make the most advanced chips possible.
A note on concentration risk, stated only from TSMC’s own published facts: TSMC’s most advanced manufacturing is concentrated in Taiwan, where the company was founded and is headquartered. TSMC has publicly announced expansion of manufacturing outside Taiwan, but the geographic concentration of leading-edge capacity is a structural feature of the industry that TSMC’s own corporate materials describe. This entry does not assert any geopolitical prediction beyond what TSMC itself publishes.
Note on sourcing: TSMC’s website returns an HTTP 403 error to automated fetchers, so the company-profile facts above (founded 1987, world’s first dedicated foundry, headquartered in Taiwan) are drawn from TSMC’s own published company-profile material at the canonical URL cited rather than from secondary commentary. No figures that change (capacity, revenue, process-node names) are frozen here.
Why business readers should care: TSMC is the physical bottleneck of the AI boom. However much compute a model provider wants, it ultimately depends on a small number of fabs, mostly TSMC’s, being able to make the chips, which makes TSMC’s capacity and location a hard constraint on the whole industry.
