TSMC manufactures chips designed by many leading technology firms.
Taiwan Semiconductor Manufacturing Company, abbreviated TSMC, is the world's leading dedicated semiconductor foundry. A foundry manufactures integrated circuits for customers that generally design the chips themselves instead of selling branded processors under the foundry's name.
TSMC was founded in Taiwan in 1987 by Morris Chang. Its pure-play foundry model helped separate chip design from chip manufacturing, allowing companies such as fabless processor designers to use advanced production facilities without owning their own fabs.
TSMC manufactures chips for a wide range of customers and markets, including smartphones, high-performance computing, automobiles, and artificial intelligence. It is not the same kind of company as Nvidia: Nvidia primarily designs chips, while TSMC primarily manufactures chips for customers, including Nvidia.
