CHASKA, Minn.--(BUSINESS WIRE)--July 10, 2005--

Facility Is An Industry, Company First For The Asia Pacific Country

Entegris, Inc. (Nasdaq:ENTG) announced today that it is opening a new regional service center in Chin-Yu, Taiwan. The facility is the first such operation in Taiwan, and will begin business this week (July 11) in submicron cleaning, logistics and product repair to support semiconductor, data storage and flat panel display customers. The company invested nearly $3 million in capital improvements in the leased facility this spring, will employ up to 30 employees to start up, and will be the only such facility of its kind in Taiwan. The Chin-Yu service center is just a few miles north of Entegris' administrative/sales office in Hsinchu, Taiwan.

The facility features the most advanced technology in submicron cleaning, RFID tracking and metrology equipment to clean and certify semiconductor wafer carriers and shipping products - doing so with ultrasonic cleaning, vacuum drying and high throughput capabilities. The 22,000-square foot facility recreates actual fab environments, and features clean rooms ranging from Class 10,000 down to Class 1 certified clean environments. Entegris' combination of facilities, equipment and process knowledge provides wafer-ready products directly from its service center to customers, enabling them to focus on chip making activities and use more of their fab space for production work.

"Entegris is excited and proud to make this investment in Taiwan. This brings us even closer to our valued customers here, providing them with solutions support for a competitive edge in the marketplace," said Bill Shaner, Entegris vice president of solutions marketing. "This new facility sets Entegris far apart from the competition, and enhances our industry leadership with our global network of regional service centers in the United States, Europe and Asia Pacific."
