CHANDLER, Ariz., Oct. 4 -- Amkor Technology, Inc. (Nasdaq: AMKR) said today that it has completed the sale of the assets of its Amkor Test Services business unit ("ATS") to several members of the ATS management team for an undisclosed sum. Based in Wichita, Kansas, ATS provides semiconductor test services for military, avionics and commercial- grade applications. ATS also operates a small ESD testing facility located in Santa Clara, California.

"The sale of ATS, which represents less than one percent our revenue, reflects our desire to sharpen Amkor's operational focus on our core assembly and test business," said John Boruch, Amkor's president and chief operating officer. "This transaction will also allow ATS to pursue business within market segments that historically have been outside of Amkor's core business operations."

Amkor is a leading provider of contract semiconductor assembly and test services. The company offers semiconductor companies and electronics OEMs a complete set of microelectronic design and, manufacturing and support services. More information on Amkor is available from the company's SEC filings and on Amkor's web site: www.amkor.com.
