The person in charge of the Hsinchu Science Park said that TSMC's future 1nm factory will be located in the Longtan Park in Hsinchu, and the plan for the third phase expansion of the Longtan Park was released recently. The director of the Bamboo Administration, Wang Yongzhuang, recently revealed that the three-phase expansion plan of the Longtan Park has been submitted to the executive branch, and if everything goes smoothly, the target will be available for manufacturers to start building factories in mid-2026.

The industry said that this means TSMC's 1nm plant can start groundbreaking in 2026 at the earliest, with trial production in 2027 and mass production in 2028 at the earliest, which is consistent with the previous industry speculation process.

The report said that by then, TSMC's most advanced process in overseas plants should still be at 3nm, allowing TSMC to continue to leave the industry's most advanced process in Taiwan, China, and major global customers will still rely on TSMC's Taiwan, China plant production of the latest chips. If you really want to advance the deployment of Taiwan's advanced semiconductor process, the nearest choice of Longtan Science Park is the most ideal place, and will bring tens of thousands of jobs to Taoyuan, which in turn will drive the development of the entire local economy in Taoyuan.
