Lam Research Corporation Takes Metal Processing To New Level With New TCP® 9600DFM

Lam Research Corporation Takes Metal Processing To New Level With New TCP® 9600DFM FREMONT, Calif., June 18, 2001 - Lam Research Corporation (Nasdaq: LRCX) today released the TCP 9600DFM (Designed For Manufacture) high-density metal etch system. The new system provides superior throughput, availability, and performance for sub-150 nm applications. Several design advances combine to virtually eliminate the cost of consumables (CoC). Together, these advances make the new TCP 9600DFM the industry's most productive, reliable, advanced metal etch system available.

"The TCP 9600DFM opens the process window by improving the resist and oxide etch rate uniformities -without compromising critical dimension (CD) uniformity," stated Dr. Richard Gottscho, Lam's vice president of conductor etch technology and engineering. "This increases process flexibility for more demanding applications, which significantly lowers cost of ownership (CoO)."

Productivity enhancements include advances in etch rates, mean time between clean (MTBC), and mean time between failure (MTBF)-and a broad process window for superior on-wafer performance. Key design changes combine to extend component lifetime for a lower overall CoC and provide a consistent chamber environment for predictable process results on small geometries. The net result of the new system's advanced design is an extremely low cost of consumables and superior CD control.

According to Alan Walker, Hynix Semiconductor Manufacturing of America, "We have tripled our MTBC to more than 300 RF hours and are extremely pleased with performance of the new TCP 9600DFM system. In making the transition from Lam's TCP 9600PTX, we experienced only a slight process shift and an easy requalification process. In addition, based on our experience to date, we are anticipating a drop in overall CoO as well."
