Tessera Brings Chip-Scale Packaging Capabilities to North Dakota State University; NDSU Electronics Center Ready to Assemble CSP-based Semiconductor Products for Technology Companies and Government Agencies.

SAN JOSE, Calif. -- Tessera Technologies, Inc. (Nasdaq:TSRA), a leading provider of miniaturization technologies for the electronics industry, today announced that it has completed a successful chip-scale packaging (CSP) technology transfer to North Dakota State University (NDSU) and has partnered with NDSU in the development of a fully functional microelectronics center at the university. As part of a multi-year government program sponsored by the Defense Microelectronics Activity (DMEA), Tessera has licensed its MicroBGA(R) CSP technology to NDSU and has provided the university with the technical knowledge and training necessary to package and assemble semiconductor chips, such as EEPROM, DRAM and Flash memory. These semiconductor devices are widely utilized in defense, medical, wireless, consumer and computing electronics to meet next-generation miniaturization, performance and reliability requirements.

Today's announcement marks the culmination of a joint effort by Tessera and NDSU to create a regional microelectronics center supporting the manufacturing needs of government agencies while facilitating the growth of technology companies.

"We are very excited about our partnership with NDSU in developing a world-class microelectronics packaging R&D center," said Nicholas Colella, senior vice president of the Product Miniaturization Division at Tessera. "NDSU gains a new resource for winning advanced development funding, while advancing its educational and research facilities. Tessera gains access to an academic community that will be applying new materials to chip-scale packaging. We hope to use this successful technology transfer as a model for future government and academic programs."

"The technology NDSU licensed, coupled with the packaging and assembly knowledge we've gained from Tessera, brings exciting new entrepreneurial and educational opportunities to NDSU faculty, students and business partners," said Philip Boudjouk, vice president for research, creative activities and technology transfer at North Dakota State University. "Having a commercially viable semiconductor packaging and assembly capability on campus is a strong indicator of NDSU's commitment to the pursuit of engineering excellence."

With fully qualified Class 10,000 and Class 100 clean rooms in place, NDSU is now ready to realize the benefits of its efforts, including new manufacturing relationships with its existing business and research partners, and eligibility for additional government funding. The Center for Nanoscale Science and Engineering at NDSU conducts electronic miniaturization research and fabrication for micro-sensors and nanotechnology, using traditional semiconductor processes. The Class 100 rooms include an Alien Technology(R) Corporation NanoBlock(TM) fabrication line. The Class 10,000 rooms house a chip-scale packaging fabrication line.

The work completed by NSDU and Tessera was sponsored by the DMEA, an arm of the U.S. Department of Defense (DoD). NDSU is currently in the process of fabricating chip-scale packaged devices to be used in the DoD-DMEA's Chameleon program, which aims to develop wireless, low-observable surveillance sensors combined with a high-sensitivity base station receiver to provide a method of collecting more accurate intelligence information for enhanced security and safety, effective military engagement and rapid dissemination of intelligence data to decision makers.
