CHANDLER, Ariz., April 19 - Amkor Technology, Inc. today announced that it is providing assembly and test services to THine Electronics, Inc., a rapidly growing fabless semiconductor company based in Tokyo. Initially, Amkor will assemble and test THine's new RF chip for cell phone applications using Amkor's MicroLeadFrame® package, which has been designed to meet Japan's QFN specifications. Amkor will perform the assembly and test at its J1 factory in Iwate, Japan, with volume production starting in the second quarter of 2004.

"Our partnership with Amkor gives us both domestic and regional assembly and test with enough production capacity of more than one million pieces per month, which is crucial to our corporate expansion goals," said Dr. Tetsuya Iizuka, president and CEO of THine Electronics. "Because the first product that Amkor is packaging for us is our introduction into the cell phone RF market, we want to keep assembly and test in a domestic location to ensure that we meet our customer's goals. However longer term, we believe Amkor has the operational capabilities to provide THine with world class assembly and test support from several locations as we expand our presence in Asia."

"Our emerging business relationship with THine is another element contributing to Amkor's position as the leading provider of contract semiconductor assembly and test in Japan," said Jim Fusaro, senior vice president and general manager of Amkor Japan. "We look forward to supporting THine in their efforts to capitalize on growing market opportunities in Japan and throughout Asia."
