Item 2.01. Completion of Acquisition or Disposition of Assets.

     On August 19, 2004, Amkor Technology, Inc., a Delaware corporation (“Amkor”), acquired approximately 93.0% of the capital stock of Unitive Inc., a Delaware corporation (“Unitive”), and on August 20, 2004, Amkor acquired approximately 60.0% of the capital stock of Unitive Semiconductor Taiwan Corporation (“UST”).

     Amkor acquired the capital stock of Unitive pursuant to a Stock Purchase Agreement dated as of July 19, 2004 (the “Unitive Agreement”), by and among Amkor, Unitive, certain former stockholders of Unitive, certain former holders of options to purchase capital stock of Unitive, Onex American Holdings II LLC, David Rizzo, Thomas Egolf, Kenneth Donahue and U.S. Bank National Association. The consideration payable under the Unitive Agreement consists of a cash payment of approximately $12.3 million at closing, the assumption of approximately $5.7 million of debt at closing, an additional $15.5 million on the one-year anniversary of closing (payable in cash or in Amkor common stock at Amkor’s option) and a contingent payment of up to $55 million (payable in cash or in Amkor common stock at Amkor’s option) to be paid, if at all, upon the achievement of certain performance goals described in the Unitive Agreement. Unitive is a leading independent developer of electroplated wafer bumping technology and earlier this year announced the industry’s first electroplated lead-free wafer bumping process.

     Amkor acquired the capital stock of UST pursuant to a Stock Purchase Agreement dated as of June 3, 2004 (the “UST Agreement”), by and among Amkor, UST, and certain shareholders of UST, as amended by a letter agreement dated July 9, 2004. The consideration payable under the UST transaction consists of a cash payment of approximately $19.4 million at closing, the assumption of approximately $16.3 million of debt at closing, the payment of approximately $450,000 in other costs and a variable contingent cash payment to be paid, if at all, based on the achievement of certain performance goals described in the UST Agreement, which payment is currently estimated to be approximately $2 million. In addition, Amkor has a call option to acquire the remaining approximate 40.0% of UST at any time over the next 18 months. Amkor is required to exercise the call option if UST achieves certain goals within such 18-month period. The exercise price of this option, which is currently estimated to be approximately $18.0 million, is based on a formula taking into account, among other things, the performance of UST. UST is a provider of electroplated wafer bumping services.

     The terms of the acquisitions are more fully described in the Unitive Agreement and UST Agreement, as amended.

     Item 9.01. Financial Statements and Exhibits.

     (a) and (b) All financial information required by this Current Report on Form 8-K in connection with Amkor’s acquisition of capital stock of Unitive and UST will be filed by amendment to this Current Report on Form 8-K within sixty days (60) from the date this Current Report on Form 8-K must be filed.
