TSMC is the largest publicly traded semiconductor foundry by market capitalization.
Taiwan Semiconductor Manufacturing Company, usually called TSMC, specializes in manufacturing chips designed by other companies. This business model is known as a dedicated semiconductor foundry. TSMC does not generally sell processors under its own consumer brand; instead, it fabricates designs for customers such as Nvidia, Apple, and AMD.
The company was founded in Taiwan in 1987 by Morris Chang. Its rise helped establish the modern separation between chip design and chip manufacturing. This specialization lets many technology companies develop advanced processors without owning comparable fabrication plants.
TSMC’s market value reflects its position in the global supply chain, especially its ability to manufacture highly advanced chips. Market-cap rankings remain fluid, but the company is consistently among the world’s most valuable semiconductor businesses.
