Class-D Audio Market Growing by over 50%, Estimated at nearly $600 Million in 2008

NEWPORT BEACH, Calif., and SEOUL, South Korea, April 7, 2009 - Tower Semiconductor, Ltd. (NASDAQ: TSEM, TASE: TSEM), and its fully owned U.S. subsidiary Jazz Semiconductor, Inc., today announced that Cesign, a Korean-based fabless analog semiconductor company, has selected Jazz's leading-edge power management technology, a 0.25-micron Bipolar- CMOS-DMOS process (BCD25) to develop and manufacture its innovative Class-D amplifier targeted for the consumer electronics market. According to Research in China, the Class-D Audio market is growing at a rate of above fifty percent. In 2008, its market size was estimated at nearly $600 million. Cesign chose Jazz's BCD25 process to achieve the best cost and die size due to its industry first Scalable Rdson Technology.

Jazz's BCD25 process technology offers the first scalable Rdson versus breakdown voltage design kit technology enabling optimized area for every transistor. BCD25 provides significant cost reductions by allowing designers of power devices to achieve a significant shrink in device area size. In addition, the BCD25 process offers advanced CMOS, a combination of bipolar NPN and PNP devices, as well as high voltage LDMOS FETs that take advantage of 0.25- micron rules to reduce on-resistance and size of power cells used in complex power management chips.

Cesign's current Class-D amplifier chip (CPA series) offers a unique PWM (pulse width modulation) called XCM (Cross Coupled Modulation). An ultimate total THD+N (harmonic distortion plus noise) result (THD+N 0.01%) is accomplished with XCM technology which delivers precise audio sound with high power compared to other Class-D amplifier manufacturers. Target applications for Cesign's Class-D amplifier include cellular phones, smart phones, Bluetooth headsets, portable audio, FPTV, LCD monitor and docking station for music player.

"We chose Jazz as our foundry supplier for their fully scalable options, excellent support and design kits, and leading-edge power management technology," said Kim JeongPyo, CEO of Cesign. "We are especially impressed by their design kit and its unique scalable Rdson capability which creates the smallest die size possible. In addition, we chose Jazz for their excellent local Korean sales and technical support."

"Our 0.25-micron BCD process is targeted for custom designs including driver ICs, battery and portable power management, power control for PC products, and Class-D audio amplifiers for both fixed and low-power mobile applications. Our innovative Scalable Rdson Technology embedded in our full design kit, along with our modeling support, enables customers like Cesign to optimize performance and cost for their products while greatly reducing design cycle times," said Dr. Marco Racanelli, Senior VP and General Manager, RF and High Performance Analog Business Group, Jazz Semiconductor.
