TOWER SEMICONDUCTOR MOVES FORWARD ON 0.13-MICRON TECHNOLOGY WITH TOOLSET PURCHASE MIGDAL HAEMEK, Israel - July 13, 2004 - Tower Semiconductor Ltd. (NASDAQ: TSEM; TASE: TSEM) today announced that it expects to ramp production of 0.13-micron technology node in Fab 2 early next year. The company has ordered the first toolset to equip Fab 2 to manufacture next-generation devices. "Tower is firmly on course for a timely migration to the 0.13-micron industry standard technology node," said Doron Simon, president of Tower USA. "We have proven silicon and stable yield performance at Motorola's fab and our team has begun transferring the technology to Tower. We are now qualifying initial IP's and are in discussions with lead customers for ramping this technology node at Tower's Fab 2." The advanced-systems purchases include a 193nm scanner and additional tools, supporting all-copper process technology with the capability to manufacture 0.13-micron and below technology nodes. Including the previously ordered tools to increase 0.18-micron production capacity for Fab 2 and an initial ramp of 0.13-micron capacity, Tower expects capital-equipment expenditures to be between $150 million and $200 million this year.
