(NASDAQ: ENTG) brings its industry leading wafer and reticle handing products to SEMICON Taiwan 2006 this week in Taipei. Three leading products that Entegris will showcase this week are the 300 mm FOSB (Front Opening Shipping Box), the Spectra™ FOUP (Front Opening Unified Pod) and the RSP 200 PEEK™ dome unit. Entegris is the global market leader in purifying, protecting and transporting critical materials used in manufacturing by semiconductor companies. “Entegris’ industry standard wafer and reticle handling technology, products and services are driving the kind of advancements that deliver solutions for customers, and enable continued process development and yield improvements in the semiconductor market, here in Taiwan and worldwide,” said Patrick McKinney, vice president of wafer handling. Entegris 300 mm FOSB (photo below) As 300 mm wafer processing moves more and more to fully automated transport of wafers, the Entegris FOSB features state-of-the art technology that helps customers to realize process consistency and cost savings. With its unique FIMS compatible door, Entegris’ FOSB enables fabs to more efficiently and effectively complete their transition to a full automation environment. (CONTINUED ON NEXT PAGE) The materials integrity management company ENTEGRIS BRINGS PRODUCT INNOVATIONS TO SEMICON TAIWAN…September 11, 2006…….…page 2 Entegris Spectra™ FOUP (photo below) The Spectra™ features the newest and best technology for 300 mm wafer transport, enabling customers to reach advanced technology nodes of 90nm and lower. It is fully compatible with all process tools and automation equipment to achieve the highest tool uptime available. The Spectra™ FOUP promises higher yields due to a proven design to protect wafers from particles, airborne molecular contamination, shock and vibration better than any other FOUP in the market. Entegris On-Site Services experts maintain the Spectra™ FOUP at the customer site. The Spectra™ FOUP features an advanced ESD path to ground, and supports many types of identification strategies. Entegris RSP 200 PEEK™ Dome Higher cleanliness standards (both particulate and molecular) are driving the need for improved performance by the products designed to transport and store masks during manufacturing. Entegris introduces this month a technological advancement unmatched in the industry with its RSP 200 PEEK™ dome unit mask handler. Entegris developed the product in collaboration with the Advanced Mask Technology Center (AMTC). The Advanced Mask Technology Center GmbH & Co. KG (AMTC), a joint venture of Advanced Micro Devices, Inc., Infineon Technologies AG and Toppan Photomasks, Inc., is one of the world's leading centers for the research and development, as well as pilot production of, optical photomasks for the latest lithographic generations. The RSP 200 features significant abrasion improvement by incorporating PEEK material in the dome unit that better protects load ports and storage areas, provides improved sealing between the dome and the door, reduced outgassing and greater ESD protection – thereby providing overall greater contamination control, reduced risk of mask damage and enhanced yields. This new Entegris innovation (in comparison to the previous dome design) provides 12 times the abrasion resistance, 50 times sealing improvement and 1,500 times the improvement in reducing outgassing. Its interior is 18 percent smaller than the earlier dome, creating a smaller area in which to control contamination. The product is now available for orders and shipping.
