SAN JOSE, Calif. -- Tessera Technologies, Inc. (Nasdaq:TSRA), a leading provider of miniaturization technologies for the electronics industry, today announced that it has signed a new technology licensing agreement with NXP B.V., one of Europe's largest semiconductor companies. NXP, formerly Philips Semiconductors B.V., uses Tessera's advanced packaging technologies in many semiconductor devices, such as application specific standard products (ASSPs), digital signal processors (DSPs), application specific integrated circuits (ASICs), and microcontrollers. These devices are integrated into a wide range of products, including consumer, wireless, and communications electronics.

"Tessera's technologies have enabled NXP to provide a more vibrant and enhanced media experience to its consumers," said Christopher Pickett, executive vice president, technology licensing and general counsel. "We are delighted to have reached this agreement with one of the world's most innovative electronics companies, and we look forward to working with NXP as they continue to introduce next-generation products to their customers."

Tessera's recent agreements with the world's top semiconductor companies underscore the value of Tessera's technologies and the vital contribution the company is making to the development of today's highly complex electronics. In addition to NXP, Tessera has recently reached agreements with a number of global leaders, including: Infineon Technologies AG and Qimonda AG, two of Europe's leading semiconductor companies, and Micron, the world's fourth largest DRAM manufacturer.

Under the terms of the agreement, NXP has licensed Tessera's semiconductor packaging technology for use across NXP's semiconductor device portfolio. The technology available to NXP 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. Tessera's intellectual property is utilized in many forms of advanced packaging, covering an extensive range of materials and assembly processes.
