2004 SiP Symposium Maps the Course for Next-Generation Electronics Miniaturization.

SAN JOSE, Calif. -- Industry Experts Explore the Future of System-in-Packaging Technologies and Emerging Electronics

Tessera Technologies, Inc. (Nasdaq:TSRA), a leading technology developer and services provider for semiconductor chip-scale and multi-chip packages (CSPs and MCPs), today provided further details of the agenda for its 2004 System-in-Package Symposium (SiP), to be held Tuesday, July 13, 2004, at the Hyatt Sainte Claire Hotel in San Jose, California. This prominent forum will feature leading technologists exploring how the semiconductor industry can develop low-cost, small-size, high-performing electronic products and systems using advanced SiP technologies.

Dr. David Tuckerman, Tessera's chief technical officer, will open the half-day symposium with a discussion on how to lower the risks associated with SiP implementation. The following industry experts join Tuckerman on the roster:

--Jim Walker, vice president of research at Gartner Dataquest, will discuss market trends, applications and analysis for multiple-die packaging.

--Intel's Steve Greathouse, non CPU pathfinding program manager, will examine stacked die and system-in-package applications.

--Mike Steidl, Amkor Technology's senior vice president of advanced product development, will discuss the latest in SiP package solutions.

--SMART Modular's Arthur Sainio, senior strategic marketing manager, will explore the advantages and economics of stacking high performance memory.

--Nokia's Dr. Viswanadham Puligandla, principal scientist, Nokia research center, will outline the road to reliable lead-free consumer bound electronics.

--A special report on the changing requirements for package substrates will be provided by Jan Vardaman, president, TechSearch International.

--Larry Czapla, senior vice president of the medical business group at PEMSTAR Medical, will examine enabling solutions for miniature medical electronic applications.

--Tessera's Craig Mitchell, vice president of marketing, will discuss the benefits of system-level integration and miniaturization.

--Gene Selven, publisher of ChipScale Review Magazine, will provide closing comments.

Tessera and Chip Scale Review Magazine have teamed to sponsor this Symposium, which will be held the week of SEMICON West, on Tuesday, July 13, at the Hyatt Sainte Claire Hotel, across the street from the San Jose Convention Center. The half-day symposium will run from 1:00-5:30 p.m., followed by a reception from 5:30-7:00 p.m. Last year's event was standing room only, so interested attendees are encouraged to register early at www.tessera.com.
