TSMC, short for Taiwan Semiconductor Manufacturing Company, became a major market-cap leader through its specialized semiconductor-foundry business.
TSMC was founded in Taiwan in 1987 by Morris Chang. Its pioneering model was to manufacture chips designed by other companies instead of competing directly with those customers through its own branded processors. This helped create the modern dedicated-foundry industry.
Companies such as Nvidia, Apple, and AMD rely on advanced manufacturing partners for important chips, and TSMC is a central supplier for leading-edge production. Demand for smartphones, high-performance computing, and artificial intelligence has made its manufacturing capacity strategically important.
TSMC’s market capitalization reflects both its earnings and the importance of advanced chip production. It is often confused with chip designers such as Nvidia or device companies such as Apple, but TSMC primarily manufactures semiconductors designed by others.
