Lam Research Corporation Purchases Post-CMP Cleaning Technology From Oliver Design, Inc FREMONT, Calif., November 15, 1999-Lam Research Corporation (Nasdaq: LRCX) today announced the purchase of research and development technology from Oliver Design, Inc. The purchase includes Intellectual Property rights related to cleaning semiconductor wafers, as well as licenses to develop semiconductor applications for Oliver's leading-edge cleaning technology originally developed for the disk drive industry. A key benefit of the technology purchase is the enhancement of development activities in connection with a 300 mm cleaning design, elements of which can be incorporated into Lam's TeresTM integrated Chemical Mechanical Planarization (CMP) system.


“Oliver's technology is an excellent match for our CMP and post-CMP wafer cleaning product portfolio,” said Dr. Willy Krusell, Lam's vice president CMP/Cleaning Engineering/Technology. “Due to the rapidly growing market acceptance of Teres, and our customers' requirements for a 300 mm product solution, we will begin integrating the Oliver design into our 300 mm CMP and cleaning development efforts,” concluded Krusell.

In connection with the purchase, which totals approximately $8.8 million, Lam will take a one-time charge of approximately $7.3 million during the current quarter of its fiscal year 2000. Lam may make up to $2 million in additional license payments to Oliver, in the event it is successful in commercializing the technology. Those additional license payments will be charged to future periods, as incurred.
