FormFactor Selected by Tera Probe as Strategic Wafer Test Solution Provider; Major Wafer Testing Service Chooses FormFactor KGD Technology Wafer Probe Solution

FormFactor, Inc. (Nasdaq:FORM), a leading provider ofadvanced wafer probe cards, today announced that Tera Probe Inc. haschosen FormFactor as its strategic partner for wafer probe cardtechnology. Tera Probe, a testing service venture formed by AdvantestCorporation, Kingston Technology, Powertech and Elpida Memory, Japan'sleading global supplier of dynamic random access memory (DRAM), bringstogether its founders' respective test equipment, assembly and testingservices, memory products and wafer technology -- and now FormFactorwafer probe solutions -- to serve Elpida and other semiconductormanufacturers.

Shrinking consumer electronics such as cellular phones and mobiledevices continue to demand greater performance from smaller systempackages and, as a result, device manufacturers face mounting packageproduction costs coupled with the need for more test insertions toassess complex function. A major cost factor in system packages is thetime and costs to package and test die that are ultimately identifiedas "bad." Wafer-level final test prior to packaging verifies knowngood die (KGD), and is emerging as an important strategy formaximizing yield, cutting costs and minimizing revenue loss due toflawed components that cause package failure. Tera Probe is adoptingKGD test for mobile memory devices targeting the burgeoning consumerelectronics memory segment.

"FormFactor offers the industry's only comprehensive KGD solutionand was clearly the right choice for our wafer probing requirements,"said Masahide Ozawa, president, Tera Probe. "Not only does FormFactorshare our vision for KGD, its proven products and its commitment tofurther enhancements of KGD-yielding technology promise the lowestrisk for us as we put our strategy into action."

FormFactor introduced UPstream, its wafer-level burn-in testsolution, at the KGD Packaging and Test Workshop in September. The newproduct rounds out FormFactor's suite of advanced technology includingwafer sort and at-speed test products comprising its total solutionfor KGD test.

"Tera Probe's selection of FormFactor as its strategic supplierunderscores the value of our technology innovation and world-classproduction capabilities," said Joe Bronson, president, FormFactor."FormFactor solutions will give Tera Probe a crucial advantage inmeeting market demand. When it comes to delivery, our use ofcutting-edge micro-electro-mechanical systems (MEMS) technology andability to scale production will ensure Tera Probe the support theyneed to operate as a global test services provider."
