JSR has announced plans to build its first photoresist manufacturing plant in Taiwan in partnership with TSMC, with the facility potentially operational by 2028. This investment strengthens Taiwan's advanced semiconductor supply chain as photoresists are critical materials for cutting-edge lithography processes.
The move signals TSMC and suppliers' commitment to domestic capacity-building amid geopolitical supply-chain concerns. Photoresist co-development will enable tighter process control for 3nm and advanced nodes.
