TSMC Invests $17 Billion in 3-nm Chips for Japan Plant

Taiwan Semiconductor Manufacturing Company (TSMC) announced plans to invest $17 billion in producing advanced 3-nanometer chips at its facility in Kumamoto, southern Japan, marking a significant upgrade from its original intentions for the site. The decision, reported on February 5, builds on an existing plant and a second one under construction, aiming to bolster global chip supply amid rising demand for cutting-edge technology.

Originally, the second Kumamoto plant, where construction began in October 2025, was set to manufacture chips using less advanced 6- to 12-nanometer processes. However, shifting market needs prompted TSMC to pivot toward the more sophisticated 3-nanometer technology, one of its most advanced offerings. This process currently powers processors in upcoming iPhones and Nvidia's next-generation chips based on the Vera Rubin architecture. The company had planned an initial $12.2 billion outlay for the facility, but the enhanced focus requires the additional funding to handle the complexities of smaller, more efficient chip production.

The upgrade follows a recent meeting between TSMC Chairman C.C. Wei and Japanese Prime Minister Sanae Takaichi, where...
