SAN JOSE, Calif. -- Agreement with World Leading Consumer Product Manufacturer Expands Tessera's Position in Wireless and Consumer Markets

Tessera Technologies, Inc. (Nasdaq:TSRA), a leading technology developer, licensor and product development services provider for semiconductor chip-scale and multi-chip packages (CSPs and MCPs), today announced that it has signed a new technology licensing agreement with Matsushita Electric Industrial Co., Ltd. (MEI) (NYSE:MC), one of the world's leading consumer products companies and semiconductor device manufacturers in the world. MEI, best known for its 'Panasonic' brand, utilizes Tessera's chip scale packaging (CSP) technology in many semiconductor devices, including application specific standard products (ASSPs), application specific integrated circuits (ASICs), and various logic devices. Tessera's chip scale packaging has allowed MEI to develop and market consumer products such as digital video cameras and cellular phone handsets with unprecedented feature sets in very small form factors.

"Tessera is pleased to announce its new licensing agreement with Matsushita Electric, a distinguished electronics innovator for nearly a century," said Kirk Flatow, Tessera's senior vice president, marketing and sales. "Panasonic is well known for high-quality leading-edge products. By leveraging Tessera's advanced packaging technologies, Panasonic has been able to deliver extremely small, reliable, and feature-rich consumer products to the market at low cost. We look forward to supporting Matsushita, and to continuing to provide advanced packaging technologies that enable market leading innovations in future Panasonic products."

The technology available to MEI covers a broad range of chip-scale and multi-chip package types, including integrated circuit devices packaged in "face-down," "face-up," "fold-over," "stacked," and "system-in-package" (SiP) formats, utilizing many different types of materials, including packages using either tape and laminate substrates. These package types are marketed by Tessera as MicroBGA(R) for face-down orientations, MicroBGA-F for face-up orientations, and MicroZ(TM) for multi-chip solutions.
