<span> <p> <span class="bw-dateline-wrapper">BILLERICA, Mass. & TOKYO--(BUSINESS WIRE)-- </span> Entegris, Inc. (Nasdaq: ENTG), a global leader in advanced materials and purity solutions for the semiconductor industry, and JSR Corporation, a materials innovation leader and the parent company of Inpria Corporation, today announced entry into a non-exclusive cross-licensing agreement aimed at helping the semiconductor industry advance extreme ultraviolet (EUV) lithography for next generation chip manufacturing.</p> <p>“As the industry moves to smaller nodes, materials innovation, performance, purity, and reliability become inseparable,” said Olivier Blachier, SVP Chief Strategy & Innovation Officer at Entegris. “This cross-licensing reflects how innovation in semiconductors increasingly happens across the ecosystem, helping customers as they adopt next-generation lithography with greater confidence.”</p> <p>Under the agreement, Entegris and Inpria will cross-license metal oxide resist (MOR) patents, terminate current Inter Partes Review challenges (IPR2025-00267), and explore collaborative opportunities on future photoresist materials. The work is intended to span resist formulation, precursor synthesis and development, and possibly ultra-clean MOR-specific filtration along with associated delivery systems needed to ensure these new materials perform consistently in high-volume manufacturing for EUV lithography applications.</p> <p>By combining JSR and Inpria’s collective leadership in metal oxide resist materials with Entegris’ expertise in MOR precursors for CVD deposition, materials handling, and advanced MOR-specific filtration, the collaboration supports the application of advanced materials in semiconductor manufacturing as both parties scale advanced technologies for the AI era.</p> <p>"Pairing Inpria’s metal oxide resist innovation with Entegris’ purification and materials handling capabilities broadens the applicability of these technologies within the semiconductor materials ecosystem," said Toru Kimura, Senior Officer at JSR Corporation.</p> <p> <b>About Entegris</b> </p> <p>Entegris is a leading supplier of advanced materials and process solutions for the semiconductor and other high-tech industries.

The opening ceremony brought together leaders from across the semiconductor ecosystem, including key industry partners Samsung and Intel that have also committed to expanding their U.S. manufacturing footprint.</p><div id="bwbodyimg" style="width: 480px; float:left; padding-left:0px; padding-right:20px; padding-top:0px; padding-bottom:0px;"><img alt="" src="https://mms.businesswire.com/media/20251105894129/en/2632569/4/Rockrimmon-drone-hero-shot.jpg" /></div><p>The 135,000-square-foot site increases the company’s production capabilities for its most advanced products for filtration and purification, as well as semiconductor wafer carriers known as Front-Opening-Unified Pods (FOUPs) that are essential for chip purity and yield. The facility marks the return of Entegris’ FOUP manufacturing to the U.S. for the first time in decades.</p><p>“The U.S. semiconductor industry's strength hinges on a reliable and advanced domestic supply chain of critical process chemistries and solutions,” said Entegris president and CEO Dave Reeder. “We are very proud that this state-of-the-art facility will be instrumental in realizing that vision for our customers, and building a more resilient semiconductor manufacturing ecosystem here in the U.S.”</p><p>Entegris broke ground on the facility in 2023 and began initial commercial operations earlier this year to help address critical needs across the domestic semiconductor supply chain.</p><p>The Colorado Springs manufacturing facility expands Entegris’ long-standing presence in Colorado, where it has operated for more than 30 years. Construction and operation of the new facility has created several hundred direct and indirect jobs in the region, supported by up to $100 million in local and U.S. government incentives.</p><p>As the semiconductor industry grows in the U.S., Entegris is committed to helping build the local workforce by collaborating with the University of Colorado Colorado Springs, the School of Mines, and District 20 schools to provide scholarships, co-op programs, and career pathways for students in science and engineering fields and help create a self-sustaining talent ecosystem.</p><p>As part of its commitment to the region, Entegris is also partnering with Hiring our Heroes, Mt. Carmel Veterans Service Center, the SEMI Veteran Foundation, and local military bases to support its goal of hiring 50% of its workforce from veterans and military families.</p><p><b>ABOUT ENTEGRIS</b></p><p>Entegris is a leading supplier of critical advanced materials and process solutions for the semiconductor and other high-tech industries.
