TOWER SEMICONDUCTOR MANUFACTURES GEN 2 RFID TAGS FOR ALIEN TECHNOLOGY MIGDAL HAEMEK, Israel - June 14, 2006 - Tower Semiconductor Ltd. (NASDAQ: TSEM; TASE: TSEM), a pure-play independent specialty foundry, today announced that it is the manufacturing supplier for Alien Technology's internally-designed Gen 2 RFID (Radio Frequency Identification) integrated circuits. These ICs recently achieved the EPCGlobal certification mark. The RFID ICs are produced at Tower's Fab2 in an advanced 0.18-micron manufacturing process. Market analysts forecast the RFID IC's market to grow significantly to between $500 millions and $1 Billion by 2010, mainly due to the Gen 2 impact. RFID tags help enable supply chain efficiency, visibility and security and are being deployed in retail, defense, transportation and health markets. Some of the implementation initiatives are being led by major US retailers. According to the U.S. Government Accountability Office, 13 federal agencies are already using or plan to deploy RFID technology. The U.S. Department of Defense (DoD), has mandated RFID's use across its suppliers for increased supply chain visibility and improved forecasting. The newly certified Alien Gen 2 RFID chips include some new CMOS devices which were jointly developed with Tower. IC development efforts focused on the low-power requirements for such an RFID tag which draws its power solely from transmitted Radio Frequency energy. "Gen 2 protocol is the emerging standard in RFID tag technology," said Yossi Netzer, general manager of mixed-signal & RF product line at Tower Semiconductor. "We are happy that Tower's R&D and manufacturing capabilities were chosen by Alien." ABOUT TOWER SEMICONDUCTOR LTD.
