JSR Micro

What JSR Micro does

JSR Micro, Inc. is a US-based electronic materials subsidiary of Japan-listed JSR Corporation (Tokyo Stock Exchange), established in 1990 and headquartered at 1280 N. Mathilda Avenue, Sunnyvale, California. The company manufactures and supplies advanced semiconductor materials — including EUV, ArF immersion, ArF/KrF dry, and multilayer hardmask photoresists; CMP slurries; post-CMP and post-etch cleaning solutions; and packaging materials such as THB negative-tone photoresists and WPR photosensitive dielectric materials — to major chip manufacturers and the broader advanced electronics industry. Its core technology stack combines polymer design, electrochemistry, and surface chemistry, leveraging more than three decades of manufacturing and innovation heritage originating in JSR Corporation's 1977 entry into semiconductor photoresists. JSR Micro holds the number 1 position in semiconductor lithography materials and approximately 25% of the global photoresist market, supported by ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and SEMI Global Care certifications.

The company operates an enterprise-field-sales go-to-market model through wholly-owned subsidiaries including JSR Micro NV (Belgium) for European, Russian, Middle Eastern, African, Indian, and Singaporean markets, and is concurrently ramping two strategic manufacturing expansions: a joint-venture photoresist facility in Yunlin County, Taiwan with Wah Lee Industrial and LCY Chemical (co-developing EUV photoresists with TSMC, expected online by 2028), and the world's first production-scale metal oxide resist facility in South Korea through JSR Micro Korea. Revenue is generated through direct B2B sales of consumable materials into semiconductor fabs and back-end packaging lines; pricing is quote-based and not publicly disclosed, and the customer base is concentrated among advanced-node semiconductor manufacturers such as TSMC and Intel (the latter a 2018 Intel SAA award recipient). The product portfolio is organized into three core pillars — Lithography Materials, Packaging Materials, and Advanced Cleans & CMP — and is complemented by an ongoing PFAS-free PID material initiative tied to environmental regulatory and customer sustainability requirements.
