TSMC is the Taiwan-based semiconductor foundry that has repeatedly ranked among the world’s most valuable companies by market capitalization.
Taiwan Semiconductor Manufacturing Company, commonly called TSMC, pioneered the dedicated semiconductor-foundry model. It manufactures chips designed by other companies, allowing customers to focus on architecture and product development without owning fabrication plants.
TSMC produces advanced processors for customers including Nvidia, Apple, and AMD. Its importance grew as leading-edge chips became central to smartphones, cloud computing, and artificial-intelligence systems.
The company is sometimes confused with a chip designer or a branded consumer-electronics manufacturer. TSMC primarily provides manufacturing services and does not sell most products directly to consumers under its own brand. Its market value reflects both its technological lead and its strategic role in global semiconductor supply chains.
