TSMC is the Taiwan-based semiconductor manufacturer commonly identified by the stock ticker TSM.
TSMC stands for Taiwan Semiconductor Manufacturing Company. Founded in 1987, it pioneered the dedicated foundry model, manufacturing chips designed by other companies rather than primarily selling chips under its own consumer brand.
The company operates major fabrication facilities in Taiwan and has expanded manufacturing and investment internationally. Its customers include leading semiconductor designers, making TSMC a central supplier for processors used in smartphones, computers, data centers, and artificial-intelligence systems.
The ticker TSM refers to TSMC’s American depositary receipts traded in the United States. Its ordinary shares trade in Taiwan under a different local symbol. This distinction matters because company names, exchange listings, and ticker symbols are not always identical across countries. TSMC’s market capitalization is closely watched because advanced chip manufacturing is strategically important to the global technology industry.
