July 12, 2004

SAN JOSE, Calif., July 12, 2004--Novellus Systems, Inc. (Nasdaq NM: NVLS), the productivity and innovation leader in advanced deposition, surface preparation and chemical mechanical planarization processes for the global semiconductor industry, today announced that Korea's Hynix Semiconductor, Inc. will equip its new 300-mm T1 facility with a diverse range of Novellus' process equipment for both front-end-of-line and back-end-of-line applications. The multi-system order includes a series of VECTOR plasma-enhanced chemical vapor deposition (PECVD) tools, along with a range of high-density plasma (HDP) SPEED® tools, chemical vapor deposition (CVD) ALTUS® systems, a GAMMA™ surface preparation tool, and an INOVA® physical vapor deposition (PVD) system. The suite of 300-mm tools--selected for their productivity, cost-of-ownership (CoO) and extendibility advantages--will be initially deployed on the customer's 90-nm processing lines and later extended to produce devices at smaller nodes.

Commenting on the multi-system order, Sung-Suk Kang, Senior Manager, Equipment Purchasing Team, Chief Procurement Office of Hynix said, "Our positive experience with Novellus' high-productivity and low cost of ownership 200-mm tools, sealed this purchasing decision. We expect the new systems to deliver the same performance benefits at our 300-mm fab, allowing us to meet our aggressive production schedules."

"Novellus congratulates Hynix on its new facility," said the company's executive vice president of sales, service and marketing, Tom St. Dennis. "As a long time customer, we're extremely pleased that they selected our equipment to power their most advanced fab. We wish Hynix much success with their new manufacturing facility."
