Press Releases

 FREMONT, Calif., September 10, 2002—Lam Research Corporation (Nasdaq: LRCX) today announced that Advanced Micro Devices, Inc. (NYSE: AMD), Sunnyvale, Calif., has selected Lam’s 2300 Etch Series to develop next-generation logic and flash processes.

The 2300 Exelan dielectric and 2300 Versys silicon etch systems will be employed for both front- and back-end etch applications for AMD’s development efforts. The 2300 Etch Series was selected for its straightforward 200/300-mm scaling and superior etch technology. The equipment is installed at AMD’s Submicron Development Center (SDC), which supplies next-generation technology to all AMD Fabs worldwide.

“The transition to 300-mm technology helps us offer even greater benefit to our customers,” said Dr. Linton Salmon, director of Advanced Process Development for AMD. “During the transition, we need to move easily between 200- and 300-mm wafer sizes. We expect that the 2300 Etch Series equipment will enable developing 200-mm processes cost effectively followed by straightforward scaling to 300 mm.”

“Being selected for AMD’s next-generation etch processes validates the 2300 Etch Series’ process versatility and advanced capability,” said Ferdinand Seemann, Lam’s vice president of North America Field Operations.

Examples of applications in development for both logic and flash at AMD include high-aspect-ratio contact (HARC) and low k etch. AMD will also be developing in situ processing for dual damascene to implement maximum cost reduction in the back-end.
