STATS ChipPAC Offers Complete Package on Package (PoP) Solutions With Both Top and Bottom Package Technologies

Flexibility and Scalability of up to 5 Stacked Die in the Top Package Integrates With up to 2 Stacked Die in the Bottom Package

UNITED STATES -- (MARKET WIRE) -- January 29, 2007 -- SINGAPORE -- 1/29/2007 -- STATS ChipPAC Ltd. ("STATS ChipPAC" or the "Company") (NASDAQ: STTS) and (SGX-ST: STATSChP), a leading independent semiconductor test and advanced packaging service provider, today announced a complete Package on Package (PoP) solution with both top and bottom package designs for cell phones, PDAs and other handheld products. PoP is a three dimensional (3D) package technology in which two fully-tested packages are stacked during the board mount process to achieve additional functionality and configuration flexibility with a minimal increase in size.

The top package of a PoP typically integrates stacked memory devices in a Fine Pitch Ball Grid Array (FBGA) configuration, while the bottom PoP package usually contains a logic device or logic device combination (logic + logic, logic + analog, etc.). PoP solutions are customized according to the needs of the end market application and typically have a final package height of less than 1.6mm. With the ability to mix and match IC technologies as well as source devices from multiple manufacturing sources, PoP enables semiconductor companies to quickly respond to changes in market demand and modify the combination of silicon technology during final board assembly. STATS ChipPAC is in volume production on both top and bottom PoP packages.

"PoP continues to gain momentum as a flexible, successful integration technology which delivers increased device density and functionality in a smaller footprint to support the needs of the handset market. PoP solutions enable a lower mounted height approaching 1.4mm for certain package combinations," said Dr. Han Byung Joon, STATS ChipPAC's Executive Vice President and Chief Technology Officer. "The ability to offer a single manufacturing source for both top and bottom packages provides a number of benefits to our customers, including increased design compatibility, tightly controlled warpage, increased reliability, and improved board mount yields."

PoP provides significant versatility in combining top and bottom packages from different manufacturing sources. However, design compatibility is paramount to avoid solder reflow quality issues. When top and bottom PoP packages are stacked on the application board and reflowed together simultaneously during the surface mount process, high reflow temperatures can cause thin PoP packages to warp. Therefore, optimization of the substrate and package design, bill of materials, and assembly process are key to producing a reliable final solution with high board mount yields.

STATS ChipPAC's bottom PoP package was introduced in 2005 and is currently in volume production in both single and two die stack versions. The top PoP package design, integrating up to five stacked die, was qualified in the fourth quarter of 2006 and has quickly ramped to volume production.

Dr. Han commented, "Customers have the flexibility to mix and match our top and bottom PoP packages with other manufacturing sources or they have the benefit of a complete PoP solution from a proven technology leader. Our goal is to provide the best solution to meet our customer's needs."
