TSMC’s 1.4-Nanometer Plants in Taichung Move Ahead of Schedule

TSMC’s new 1.4-nanometer production site in Taichung is moving faster than planned, with the first of four plants scheduled for completion by April next year.

The Taichung Economic Development Bureau said the first facility, known as P1, has entered its main structural steelwork phase. P2 is undergoing foundation piling and backfilling, P3 has obtained its construction permit, and P4 is continuing through the permit application process.

The first two plants have already been contracted, with construction handled by Dacin Construction and Hu-Chu Construction. Work is also progressing on the central utility plant, office areas and other parts of the site. Supply-chain companies cited in the report said trial production could begin at the start of the third quarter next year if construction stays on schedule. Equipment installation, production-line adjustments and validation would follow, with mass production potentially beginning by mid-2028.

The city government said it has provided a single-window service for TSMC’s investment planning and coordinated construction needs across departments. The land-use plan took effect in March 2024, land acquisition was completed with help from the Science Park Administration in February last year, and the site was handed over in July before construction began in October.

The project is expected to create 4,500 jobs. The city also said its longer-term goals include full use of recycled water and renewable electricity, alongside industrial development and consideration of residents’ needs.
