Taiwan Semiconductor Manufacturing
A maker of the tiny chips that power the world's smartphones, computers, and game consoles, TSMC is the world's largest independent semiconductor foundry. It manufactures the processors that companies like Apple and Nvidia design — the A-series chips inside iPhones and Nvidia's graphics processors. Founded in 1987 by Morris Chang, TSMC pioneered the 'pure-play foundry' model, with its first factory on the campus of Taiwan's Industrial Technology Research Institute.
