Taiwan expands Tainan science park to support 1nm fabrication

Taiwan is advancing plans to establish a dedicated science park zone in Tainan to support 1-nanometre semiconductor manufacturing.

The municipal government in Tainan is collaborating with the Southern Taiwan Science Park administration to secure land and utility resources. The initiative seeks to ensure domestic foundries have the operational scale required as process geometries shrink below two nanometres.

Advanced semiconductor fabrication remains central to artificial intelligence infrastructure. Current frontier accelerators rely on cutting-edge extreme ultraviolet lithography deployed primarily across Taiwan's existing industrial clusters. Securing a domestic pipeline for 1nm manufacturing is intended to preserve this fabrication lead over the coming decade.

The Tainan development focuses on preemptive site preparation to accommodate next-generation cleanroom facilities. Ultra-advanced fabrication plants require dedicated water treatment infrastructure, high-capacity electrical substations, and vibration-isolated logistics corridors. By preparing the physical footprint early, regional authorities aim to compress construction timelines once commercial toolsets mature.

Taiwan's science park network operates under central oversight to coordinate utility provisioning directly with chipmakers. In southern Taiwan, the existing cluster already integrates leading-edge production lines for 3nm wafers alongside advanced packaging facilities. Adding capacity tailored for 1nm production expands this ecosystem, anchoring equipment vendors, chemical suppliers, and testing facilities in close geographical proximity.

International competitors continue to invest heavily to onshore advanced logic production. Subsidised fabrication projects are progressing across the United States, Japan, and Europe. Despite these overseas investments, domestic foundries continue to locate their most advanced pilot lines and process developments within Taiwan to minimise operational friction.

The Tainan site also represents long-term planning for resource resilience. Sub-2nm fabrication nodes will demand substantially higher power per wafer pass, driven partly by higher-power lithography systems. Securing stable base-load electricity and recycled industrial water supplies will dictate how quickly future facilities can achieve volume production.

As fabrication nodes approach the physical limits of silicon, will regional utility networks expand quickly enough to meet the aggressive roadmaps of the artificial intelligence sector?
