MORE THAN 10 MILLION ULC MOBILE DEVICES ARE RINGING USING MODIOTEK SOUND GENERATORS MANUFACTURED AT TOWER SEMICONDUCTOR MIGDAL HAEMEK, ISRAEL - January 9, 2007 - Tower Semiconductor Ltd. (NASDAQ: TSEM; TASE: TSEM), a pure-play independent specialty foundry, today announced that it has collaborated with Modiotek Co., Ltd., the new spin-off company from Macronix International Co., Ltd. (NASDAQ: MXIC; TSE: 2337.TT), to successfully introduce 32-polyphony sound generator into ULC (Ultra Low Cost) handset models, following manufacturing 10 millions of MAP S32i series products for the past two years. The MAP S32i is built for ULC phones with FM tuner and hands-free features. It is equipped with 32-polyphony MIDI engine based on wave-table synthesis technology, providing best performance-cost ratio handset ring-tone solution. Moreover, it has integrated 16/32ohm stereo headphone amplifier, 8ohm loud-speaker amplifier, two stereo auxiliary analog input ports for FM audio sound input and speech signal from analog base-band chip residing in the cell phone system implementation; its unique function integration provides total system cost improvement for ULC handset application. The MAP (Mobile Audio Platform) family consists of half a dozen different products, customized for the specific cellular phone models and applications which were built, using Tower's FAB2 0.18-micron mixed signal process technology and shipped during 2006. The MAP (Mobile Audio Platform) products represent a business of thousands of wafers each quarter for Tower. Among the handsets using these products are leading models by two of Top-5 handset brands and a dozen well-known handset makers. The market for ULC handsets is estimated at 48 million sets in 2007 and expected to grow to 150 million sets by 2010, according to market research company Strategy Analytics. The derived demand of sound generators is going to ramp up gradually. "In our drive to optimize our manufacturing capabilities, we selected Tower Semiconductor to manufacture our highest volume products," said J T Chung the newly appointed president and CEO of the Modiotek that develops the audio products. "Tower's excellent engineering and manufacturing capabilities resulted in fast products ramp and smooth volume delivery, which is a must in the competitive consumer business." "We are happy that Modiotek chose Tower for manufacturing the Sound Generators products family", said Yossi Netzer, general manager of the RF and Mixed Signal product line at Tower Semiconductor. "The sound generators cooperation is a good example for a close partnership that drives products success through matching technology and competitive time to market. Tower's customer support and manufacturing teams worked closely with Modiotek, to ensure smooth delivery and quality execution. We look forward to a continued working relationship with them for the coming generations of this family of products."
