TSMC is the Taiwanese semiconductor manufacturer commonly identified by the ticker symbol TSM.
TSMC stands for Taiwan Semiconductor Manufacturing Company. Founded in 1987, it pioneered the dedicated foundry model, manufacturing chips designed by other companies instead of primarily selling chips under its own consumer brand.
This model made TSMC a critical supplier for major technology companies, including businesses that design smartphone processors, graphics processors, and other advanced semiconductors. Its scale and manufacturing expertise helped make it one of the world’s most valuable companies by market capitalization.
The company’s primary Taiwan listing uses the ticker 2330, while its American depositary receipts trade in New York under TSM. Those are different trading lines representing the same underlying company, a detail that can cause confusion in market tables.
