Novellus Strengthens Market Leadership In Photoresist Strip
July 16, 2007

San Jose, Calif. – July 16, 2007 – Novellus Systems, Inc. (Nasdaq: NVLS), today announced that its GAMMA® Express&153; system, introduced at SEMICON West in 2006, is on track to become one of the most rapidly-adopted products in the company's history. Since the beginning of 2007, the company has received repeat orders for multiple GAMMA Express systems that have been installed for both advanced R&D and production applications at leading semiconductor manufacturers in Asia. The GAMMA platform with multi-station sequential processing (MSSP) is in production with leading memory, logic, and foundry fabs around the world, currently processing more than one million wafers per month. With an installed base of more than 250 systems, Novellus leads the market in 300 mm photoresist removal for high-volume manufacturing.

As the industry transitions to advanced technology nodes, photoresist removal becomes an increasingly important process step. Maintaining low silicon and oxide loss during the high dose implant strip (HDIS) process is critical to transistor performance. The GAMMA Express platform can be used for both front-end-of-line (FEOL) and back-end-of-line (BEOL) applications while providing the highest levels of technology, reliability and productivity for bulk and high dose implant strip at advanced nodes. This combination results in a lower cost of ownership while enabling a tight control on manufacturing variability, with greater than 95 percent uptime.

"GAMMA Express is gaining significant market traction as customers realize the benefits of an efficient and effective photoresist removal technology for advanced process nodes," said Kevin Jennings, vice president and general manager of Novellus' Surface Integrity business unit. "The GAMMA platform continues to win customers as a result of its high reliability, high productivity, technology extendibility to 32nm, and low cost of ownership, all supported by Novellus' global service infrastructure."
