New facility solidifies Entegris’ position as a leader in the U.S. semiconductor manufacturing ecosystem and expands domestic supply chain capabilities BILLERICA, Mass.--(BUSINESS WIRE)-- Entegris (Nasdaq: ENTG), a global leader in advanced materials science, today celebrated the grand opening of its new Colorado Springs Manufacturing Center of Excellence. 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. 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. “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.” 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. 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. 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. 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.
