TSMC is the Taiwanese chipmaker that trades in the United States under the ticker TSM and ranks among the world’s largest companies by market capitalization.
Taiwan Semiconductor Manufacturing Company, commonly called TSMC, operates a foundry business. It manufactures chips designed by other companies rather than primarily selling processors under its own consumer brand. This model made TSMC a crucial supplier to technology companies worldwide.
TSMC was founded in 1987 by Morris Chang in Hsinchu, Taiwan. Its customers have included designers of advanced processors for smartphones, computers, data centers, and artificial-intelligence systems.
The U.S.-traded TSM symbol represents American depositary shares, while the company’s ordinary shares trade in Taiwan. Market-cap comparisons generally combine the value of the company’s publicly traded equity across its listings, rather than counting the U.S. depositary shares as a separate company.
