Taiwan's TSMC begins mass production of 3nm chips

Taiwanese tech giant TSMC said Thursday it had started mass production of its 3-nanometre chips, among the most advanced to come to market. The Taiwan Semiconductor Manufacturing Company operates the world's largest silicon wafer factories and produces high-performance chips used in everything from smartphones and cars to missiles. It is also Apple's primary chip supplier. Its 3nm-process chips are expected to have more processing power while using less power, boosting battery performance.
