Screen doubles investment as Kyoto equipment site takes shape

Screen's 25-billion-yen Kyoto buildout and the FY2027 capex hike to 58 billion yen are not a capacity play—they are a preemptive lock on the cleaning-equipment chokepoint. Technical cascade: At 3nm GAA and HBM4 stacks, wet-cleaning steps have ballooned from roughly 40 at 16nm to 80-plus, with particle tolerance compressed to sub-nanometer levels. Screen is staking its claim on the post-2028 advanced-node window, precisely when Tokyo Electron's dry-clean penetration and Lam's single-wafer platforms hit their inflection simultaneously. Upstream quartz ware, ultra-pure chemicals, and precision flow-control valves will see order-mix shifts within 18 months. Compliance and supply chain: Japan's export-control list already covers certain cleaning tools. By building domestically rather than offshore, Screen is buying geographic redundancy against decoupling tail-risk. Yet core sensors and specialty alloys still flow through trans-Pacific supply chains; further US tightening on component exports will squeeze its BOM cost base in 2026–27. Competitive response: Lam will likely unveil a next-gen single-wafer cleaner in H2 2025; TEL will accelerate bundling cleaning modules into its Track systems. Screen's moat is three decades of wet-process know-how, but diminishing capex returns force it to trade volume for time. 12–24-month tail: Cleaning equipment is migrating from standalone units to integrated process modules. If Screen cannot validate online integration with CVD and etch by 2028, its standalone premium erodes structurally.
