A portion of this investment will be used to develop its Aurora, Illinois location, strategically located between semiconductor hubs in New York, Ohio, Arizona and Texas, into a state-of-the-art U.S. Technology Center. This facility will be a cornerstone to Entegris’ solutions selling strategy focused on maximizing product performance and minimizing time to market, across its complete suite of solutions including its deposition materials, slurries, cleans, and CMP pads.

The investments in the U.S. will leverage a strong talent base and demonstrate Entegris’ commitment to supporting advanced semiconductor manufacturing and driving technology leadership. This investment complements Entegris’ previous commitment of $700 million to development of a state-of-the-art manufacturing center of excellence in Colorado Springs, CO.

“To support the industry’s growth, we have been creating a stronger and more resilient domestic semiconductor ecosystem in the U.S.,” said Entegris president and CEO Dave Reeder. “These investments also allow for continued leadership in advanced materials solutions.”

As the semiconductor industry expands in the U.S., the need for new domestic capacity and additional collaboration on innovation will grow. Meeting these demand levels will create new opportunities for semiconductor materials suppliers to meet current and future needs.
