What Inpria does
Inpria Corporation is a specialty semiconductor materials supplier that designs, develops, and manufactures metal oxide photoresists for Extreme Ultraviolet (EUV) lithography. Founded in 2007 as a spin-out from Oregon State University's Department of Chemistry and headquartered in Corvallis, Oregon, the company produces photoresists built on organometallic clusters with a tin-oxide core — a chemistry distinct from conventional polymer-based resists. Inpria claims its materials deliver superior EUV absorption, eliminate the acid diffusion mechanism of chemically amplified resists, and offer unparalleled etch selectivity, enabling simpler manufacturing flows at advanced nodes.
The company's products are sold as part of a holistic solution that includes photoresists, developer, and ancillary materials. Manufacturing is conducted at an advanced plant in Corvallis designed to meet semiconductor industry standards with integrated Statistical Process Control. Inpria sells exclusively to semiconductor manufacturers that have adopted EUV lithography, engaging through deep enterprise co-development relationships rather than transactional sales. Its only publicly named customer is SK hynix, with which it announced co-development of metal oxide resists for next-generation DRAM in August 2022. An investor syndicate including TSMC, Samsung Ventures, Intel Capital, and SK Hynix — each major logic and memory manufacturer — signals broad strategic alignment with leading-edge fabs.
Inpria became a wholly-owned subsidiary of JSR Corporation in November 2021, which provides market reach and capital. JSR itself was acquired by Japan Investment Corporation (JIC) in 2023, and as of 2026 JIC is reportedly exploring a sale of JSR. Inpria operates as a private, pre-revenue-disclosure subsidiary with 11-50 employees and approximately $68.9M in total venture funding raised prior to the JSR acquisition. The company expanded its commercial moat through a 2026 cross-licensing and collaboration agreement with Entegris covering MOR patents and adjacent filtration technology.

Inpria partnerships and signals
Strategic signalPartnerships
Two partnerships are on record, tiered core.
- Entegris, Inc.coreNon-exclusive cross-licensing agreement for EUV lithography technology. Parties cross-license metal oxide resist (MOR) patents, terminate pending Inter Partes Review challenges, and explore collaborative opportunities on resist formulation, precursor synthesis, and MOR-specific filtration for high-volume EUV manufacturing. Combines Inpria's resist materials expertise with Entegris' purification and materials handling expertise.
- SK hynix Inc.coreCo-development partnership to apply Inpria's EUV metal oxide resist technology for manufacturing advanced DRAM chips. Supports SK hynix's technology roadmap as the semiconductor industry moves to smaller critical dimensions. Inpria's metal oxide photoresist platform enables efficient patterning of advanced node device architectures while significantly reducing cost of EUV patterning through standard spin coating process.
