JSR to build first Taiwan photoresist plant to co-develop advanced resists with TSMC

Japanese chemical company JSR plans to build its first photoresist production facility in Taiwan to co-develop advanced resists with TSMC, closing a competitive gap relative to its Japanese rivals Tok... Read original →

JSR’s Taiwan plant isn’t merely capacity expansion—it’s a strategic move to lock in co-development leverage at the bleeding edge. Technically, photoresist must be co-optimized with EUV optics, masks, and etch chemistries; local presence slashes iteration cycles by over 50%, directly enabling TSMC’s 2nm High-NA EUV ramp. This also signals Japanese suppliers recalibrating geopolitical risk: embedding inside customer ecosystems beats relying on fragile cross-border sample logistics. TOK and Shin-Etsu already executed this playbook—JSR is playing catch-up. Meanwhile, JSR’s MOR push in Korea leverages Inpria’s IP to serve Samsung/SK hynix, but if TSMC validates MOR’s yield advantage at 2nm, it’ll force TOK to accelerate its own metal-oxide roadmap. Within 18 months, the resist supply chain will bifurcate: Korea for MOR, Taiwan for CAR/High-NA co-optimization. Chinese players remain locked out beyond ArF dry, and the window for high-end material self-reliance is rapidly closing.
