What JSR does

JSR Corporation is a Japanese specialty materials company, originally founded in 1957 as Japan Synthetic Rubber Co., Ltd., that has evolved into a leading global supplier of advanced materials for the semiconductor industry. The company manufactures photoresist materials, including EUV photoresists and metal oxide resists (MOR), used in the production of advanced-node logic and memory chips. JSR holds an estimated 20-25% share of the global photoresist market and serves the three most strategically important chipmakers — TSMC, Samsung, and SK hynix — through direct enterprise field sales with quote-based pricing. The company is headquartered in Tokyo, with major manufacturing at Yokkaichi (Japan) and a forthcoming photoresist facility in Taiwan (JV with Wah Lee Industrial and LCY Chemical, online by 2028), plus the world's first production-scale MOR plant in South Korea through JSR Micro Korea.

JSR's core technology is materials chemistry for advanced lithography, centered on patented EUV photoresist formulations and metal oxide resist technology acquired through Inpria Corporation in 2021 for $514M. Beyond semiconductor materials, the company operates a life sciences platform spanning biopharmaceutical chromatography media (now being divested to Merck KGaA), CDMO services (KBI Biopharma, Selexis), preclinical research (Crown Bioscience, MBL), and display, optical, and synthetic resin product lines. The company has demonstrated a specific industrial AI capability: a Yokogawa-partnered FKDPP algorithm system that achieved 35 consecutive days of autonomous chemical plant control, an internal manufacturing optimization rather than a customer-facing product.

JSR's business model is B2B enterprise sales of materials to a small set of major chipmakers and pharmaceutical companies, with non-publicly disclosed pricing. The company was acquired by Japan Investment Corp (JIC) — a Japanese government-backed fund — in 2023 for approximately $6.3B, and has since executed a strategic portfolio restructuring: divesting elastomers to ENEOS (2021), emulsions to Nippon Shokubai (2025), chromatography to Merck KGaA (2025), and D-Mec to Stratasys (2025), while concentrating capital on semiconductor materials expansion in Taiwan, South Korea, and through the Entegris cross-licensing partnership (2026). Reports from 2026 indicate JIC is evaluating a potential sale to Fujifilm or Mitsubishi Chemical.
