Samsung is first to start mass production of 3-nanometre chips

SAMSUNG Electronics kicked off mass production of 3-nanometre (3nm) chips that are more powerful and efficient than predecessors, beating rival Taiwan Semiconductor Manufacturing Co (TSMC) to a key milestone in the race to build the most advanced chips in the world.

South Korea's largest company will begin with 3nm semiconductors for high-performance and specialised low-power computing applications before expanding to mobile processors, it said in a statement on Thursday (Jun 30). By applying so-called Gate-All-Around transistor architecture, Samsung's 3nm products reduce power consumption by up to 45 per cent and improve performance by 23 per cent compared to 5nm chips, it said.

Samsung's push to be first to market with the latest technology is essential in its uphill climb to match TSMC, which remains dominant in the contract chipmaking, or foundry, market. The Taiwanese firm accounts for more than half of the global foundry business by revenue and is the exclusive supplier of Apple's Silicon processors for iPhones, iPads, MacBooks and desktop Mac PCs.

TSMC and Samsung are competing for large multiyear orders from the likes of Apple and Qualcomm 3nm mass production from the Taiwanese chipmaker will commence in the second half of the year, TSMC has said. Samsung will produce 3nm chips at its Hwaseong facilities and plans to extend that production to its newest Pyeongtaek fab.

"We will continue active innovation in competitive technology development and build processes that help expedite achieving maturity of technology," said Siyoung Choi, president and head of Samsung's foundry business.

Samsung's advance comes at a sensitive time for the semiconductor industry, whose place in the global geopolitical order is currently under scrutiny by leading governments. The US and China have both taken steps to bring more chipmaking capacity and expertise within their borders - arguing it's a matter of national security - and Samsung is in the process of setting up a new fabrication facility in Texas.
