Novellus Systems Sets New Industry Benchmark for PECVD Throughput with VECTOR Extreme
July 16, 2007

San Jose, Calif., – July 16, 2007 – Novellus Systems, Inc. (Nasdaq: NVLS) today launched VECTOR Extreme™ plasma enhanced chemical vapor deposition (PECVD) system – the industry's fastest PECVD tool with a throughput of up to 250 wafers per hour. VECTOR Extreme helps chipmakers reduce average process cycle times by more than 40 percent as compared to other systems available in the market. Wafer inventory in the fab is also substantially reduced, giving customers the flexibility to respond to ongoing changes in semiconductor market demand.

The increasing demand for solid-state memory in consumer electronics and computer products has fuelled a sharp rise in the capacity of fabs built to manufacture DRAM and NAND Flash memory devices. With more than twenty PECVD processing steps required to fabricate a typical memory device, PECVD system throughput is becoming an increasingly important factor in the total cycle time and wafer inventory levels at these state-of-the-art high capacity memory fabs.

Novellus' VECTOR Extreme platform delivers the industry's highest PECVD throughput by integrating up to three multi-station sequential process modules with as many as 12 deposition stations onto a central wafer-handling chamber. When using this configuration to deposit thicker films commonly used in memory device fabrication, VECTOR Extreme delivers more than twice the throughput of its nearest competitor.

"As memory fabs come on-line with planned capacities of more than 100,000 wafer starts per month, a new PECVD market segment is emerging with unique system throughput requirements," said Tim Archer, senior vice president and general manager of Novellus' Dielectric Business Group. "VECTOR Extreme has captured the attention of these mega-fabs, where the tool's high throughput allows them to reduce total tool count and shorten fab cycle time, thereby minimizing wafer inventory and ultimately lowering their end product cost."

Other PECVD products from Novellus' VECTOR family include VECTOR Express™, launched in March 2007, and VECTOR Express with Ashable Hard Mask (AHM), launched in June 2007. VECTOR Express has received rapid worldwide market acceptance since its launch and is now shipping in volume.

Shipments of VECTOR Extreme for volume production are expected to start in the second half of 2007. VECTOR Extreme achieves industry-leading throughput while maintaining process transparency to Novellus Systems' production-proven VECTOR Express PECVD system.
