Apr 19, 2001, 01:00 ET from Electro Scientific Industries

    PORTLAND, Ore., April 19 /PRNewswire/ -- The U.S. Court of Appeals for the
 Federal Circuit has affirmed the judgment of the U.S. District Court for the
 Northern District of California that Electro Scientific Industries, Inc.'s
 (Nasdaq: ESIO) pioneering link blowing patent is valid and infringed by
 General Scanning Inc.'s (Nasdaq: GSLI) memory repair systems and upgrade kits
 equipped with 1.3 micron lasers.

     Previously, a District Court jury had rejected General Scanning's
 allegations that the claims of ESI's patent 5,265,114 entitled, "System and
 Method for Selectively Laser Processing a Target Structure of One or More
 Materials of a Multimaterial, Mutilayer Device", were invalid and awarded ESI
 $13.1 million in damages for General Scanning's willful infringement of the
 patent. Based on the jury verdict, the District Court prohibited General
 Scanning and its subsidiaries and parent corporations from making, using,
 selling or offering for sale in the United States memory repair systems or
 upgrade kits equipped with 1.3 micron lasers, which infringe the asserted
 claims of ESI's '114 patent. The U.S. Court of Appeals affirmed the District
 Court judgments in all respects. The '114 patent expires in 2012.
     Donald R. VanLuvanee, Chief Executive Officer and President of ESI said,
 "We are extremely pleased that the court recognizes the innovation and
 enforceability of ESI's patented technology. As a technology leader, ESI makes
 considerable investments in intellectual property rights and we will continue
 to vigorously protect that investment."
     The patented technology is used in ESI's advanced laser repair systems,
 which produce 64 and 256 megabit memory chips and semiconductors with embedded
 memory. The systems are enabling technology for the next generation of
 semiconductor yield improvement and the most advanced laser repair systems
 available on the market.  The systems feature patented laser system
 technology, operating at a wavelength of 1.3 microns, and offer semiconductor
 manufacturers a much wider process window and higher yields than systems using
 conventional 1.047 micron laser technology.
     General Scanning Inc. merged with Lumonics Inc. of Kanata, Ontario on
 March 22, 1999 to form GSI Lumonics Inc.
