PROPOSAL ONE

ELECTION OF DIRECTORS

      There are nine candidates nominated for election to the Board of Directors (“Board of Directors” or “Board”) this year, six of our incumbent directors and three additional director nominees. Unless otherwise instructed, the proxy holders will vote the proxies received by them for the election of the nine nominees named below. Each nominee has consented to be named a nominee in this proxy statement and to serve as a director if elected. Should any nominee become unable or decline to serve as a director or should additional persons be nominated at the meeting, the proxy holders intend to vote all proxies received by them in such a manner as will assure the election of as many nominees identified below as possible (and, if additional nominees have been designated by the Board to fill any vacancies, in such manner as to elect such additional nominees). All directors are elected annually and serve a one-year term until our next annual meeting, or until their successor is duly elected. We expect that each nominee will be able to serve as a director.

Required Vote

      Directors are elected by a plurality of votes cast, so the nine candidates receiving the highest number of affirmative votes cast will be elected as directors. Votes withheld and broker non-votes are not counted toward the total votes cast in favor of a nominee.

Your Board unanimously recommends a vote FOR the

election of each of the nominees for director below.

Nominees for the Board of Directors

A total of 300,000 shares of common stock have been reserved for issuance under the Director Plan. The option grants under the Director Plan are automatic and non-discretionary. As of January 1, 2003, the Director Plan provides for an initial grant of options to purchase 20,000 shares of common stock to each new non-employee director of the company when such individual first becomes an outside director. In addition, each non-employee director will automatically be granted subsequent options to purchase 10,000 shares of common stock on each date on which such director is re-elected by the stockholders of the company, provided that as of such date such director has served on the board of directors for at least six months. The exercise price of the options is 100% of the fair market value of the common stock on the grant date. The term of each option is ten years and each option granted to a non-employee director vests over a three year period. The Director Plan will terminate in January 2008 unless sooner terminated by the board of directors. As of December 31, 2004, there are no shares available for future grant under the Director Plan. However, future grants to non-employee directors may be granted under the 1998 Stock Plan.

      If all or substantially all of our assets are sold to another entity or we merge with or into another corporation or entity, the acquiring entity or corporation may either assume all outstanding options under the Director Plan or may substitute equivalent options. Following an assumption or substitution, if the director is terminated other than upon a voluntary resignation, any assumed or substituted options will vest and become exercisable in full. If the acquiring entity does not either assume all of the outstanding options under the Director Plan or substitute an equivalent option, each option issued under the Director Plan will immediately vest and become exercisable in full.

BOARD MEETINGS & COMMITTEES

      Our Board of Directors meets approximately four times a year in regularly scheduled meetings, but will meet more often if necessary. The Board held six meetings and acted by unanimous written consent on two occasions during 2004. Each director attended at least 75% of all board and applicable committee meetings. The Board has determined that each of Messrs. Churchill, George, Hinckley, Hugo-Martinez, Knorr, Papadakis and Zug is independent under the listing standards of the NASDAQ Stock Market.

      The Board has established a compensation committee, an audit committee and a nominating and governance committee. All members of the committees are appointed by the Board and are independent under the listing standards of the NASDAQ Stock Market.

      The Compensation Committee is currently comprised of Mr. Churchill and Mr. Thomas George. The Compensation Committee: (1) reviews and approves annual salaries, bonuses, and grants of stock options pursuant to our 1998 Stock Plan and our 2003 Nonstatutory Inducement Grant Stock Plan and (2) reviews and approves the terms and conditions of all employee benefit plans or changes to these plans. During 2004, the Compensation Committee met three times apart from regular meetings with the entire Board of Directors.

      The Audit Committee is comprised of Messrs. Churchill, Hinckley and Zug, all of whom meet the experience requirements set forth in the Nasdaq rules. The Board has determined that two of our three Audit Committee members, Messrs. Hinckley and Zug, qualify as audit committee financial experts as defined by the SEC. All three members of the Audit Committee are independent as defined by the SEC. Among other responsibilities, the Audit Committee: (1) approves the hiring of the independent accountants and pre-approves all audit engagement fees, (2) pre-approves non-audit services provided to the Company by the independent accountants (or subsequently approves non-audit services in those circumstances where a subsequent approval is necessary and permissible), (3) oversees the work of the independent accountants, (4) reviews and provides guidance with respect to the external audit and the Company’s relationship with its independent accountants, (5) reviews and discusses with management and the independent accountants the contents of the Company’s periodic reports and earnings releases, (6) reviews and approves in advance any proposed related-party transactions, (7) discusses with management and internal audit representatives the activities, organizational structure and qualifications of the Company’s internal audit function and (8) reviews any reports by management or internal auditors regarding the effectiveness of, or any deficiencies in, the design or operation of internal controls. The Board has adopted a written charter for the Audit Committee which is available on our website at www.amkor.com. The Audit Committee met ten times in 2004 apart from regular meetings with the entire board. In connection with the execution of the responsibilities of the Audit Committee, including the review of the company’s quarterly earnings prior to the public release of the information, the Audit Committee members communicated throughout 2004 with the company’s management and independent accountants.

      The Nominating and Governance Committee is comprised of Messrs. Churchill and Zug. The Nominating and Governance Committee assesses prospective candidates for the Board, makes recommendations to the entire Board with regard to such candidates, evaluates the composition, organization, and governance of the Board and its committees, and makes recommendations for the board’s review with regard

to the same. The Board has adopted a written charter for the Nominating and Governance Committee which is available on our website at www.amkor.com. The Nominating and Governance Committee met two times during 2004 apart from regular meetings with the entire board.

      The Nominating and Governance Committee determines the required selection criteria and qualifications of director nominees based upon the needs of our company at the time nominees are considered. The Nominating and Governance Committee considers factors including character, judgment, independence, age, expertise, diversity of experience, length of service and other commitments.

      The Nominating and Governance Committee will consider the above factors for nominees identified by the Nominating and Governance Committee itself. The Nominating and Governance Committee uses the same process for evaluating all nominees, regardless of the original source of nomination. The Nominating and Governance Committee does not currently use the services of any third party search firm to assist in the identification or evaluation of Board member candidates. However, the committee may use such services in the future, as it deems necessary or appropriate at the time in question.

      It is the policy of the Nominating and Governance Committee to consider both recommendations and nominations for candidates to the Board from stockholders. Stockholders wishing to recommend a candidate for consideration by the Nominating and Governance Committee as nominees for election to the Board of Directors can do so by writing to our Corporate Secretary at our principal executive offices giving each such candidate’s name, home and business contact information, detailed biographical data and qualifications, information regarding any relationships between the candidate and Amkor within the last three years, written indication of the candidate’s willingness to serve if elected, and evidence of the nominating person’s ownership of Amkor stock.

      Although we do not currently have a formal policy regarding communications with the Board of Directors, stockholders may communicate with the Board of Directors by writing to us at Amkor Technology, Inc., Attn. Investor Relations, 1900 South Price Road, Chandler, Arizona 85248. Stockholders who would like their submission directed to a member of the Board of Directors may so specify, and the communication will be forwarded, as appropriate.

      Six of our incumbent directors attended the 2004 annual meeting of stockholders.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

      The Compensation Committee of the Board of Directors currently consists of Mr. Winston Churchill (Chairman) and Mr. Thomas George. No member of the Compensation Committee during 2004 was an employee of Amkor or any of its subsidiaries. Each member meets the definition of “non-employee director” under Rule 16b-3 of the Securities Exchange Act of 1934, as amended, and is an “outside director” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”).

      The Compensation Committee has overall responsibility for Amkor’s executive compensation policies and practices. The Compensation Committee’s functions include:

      Amkor’s compensation philosophy is to attract and retain top talent within the electronics industry through a multifaceted compensation approach. This includes aligning base pay with companies with whom we compete for top talent. These companies are within both the semiconductor and printed circuit board manufacturing sectors. Our approach to total cash compensation is that it should vary with Amkor’s performance in attaining its financial and operational objectives. We have an incentive program for all employees which is proportional to our profitability. In addition, we have an executive bonus program that is based on annual operational performance.

      It is the Compensation Committee’s objective to establish base salaries at levels that are comparable to those paid to executives with comparable qualifications, experience and responsibilities at other companies in the electronics industry, including semiconductor and printed circuit board companies. The Compensation Committee believes that it is necessary to attract and retain the leaders in the electronics industry, as Amkor competes with these companies for executive talent. At the end of the fiscal year, each executive officer was reviewed by Mr. Kim. The review of executive officers made in fiscal 2004 for performance related to their specific function within the organization and results achieved by them relative to key performance factors. The Compensation Committee reviewed independently these recommendations and approved, with any modifications that it deemed appropriate, the annual salary, including salary increases, for the executive officers. Industry, peer group and national survey results were also considered in making salary determinations to maintain parity of our pay practices within the electronics industry.

      In fiscal 2004, James J. Kim served as the Chairman of the Board and Chief Executive Officer of Amkor. The Compensation Committee’s criteria for determining Mr. Kim’s compensation were driven by several factors: the competitive marketplace, our position in the rapidly evolving technology sector in which it operates, our operating and financial performance in 2004 and, most importantly, Mr. Kim’s leadership and establishment and implementation of strategic direction for Amkor.

      The Compensation Committee believes that Mr. Kim’s performance throughout the fiscal year ended December 31, 2004 was outstanding and that he continues to demonstrate highly effective leadership.

      Each executive officer’s performance, as well as their total cash compensation on a peer-market level, was evaluated by the Compensation Committee to determine the appropriate cash bonus award. Additionally, industry standards regarding cash bonuses as a percentage of total base pay were reviewed to ensure alignment within the industry.

      An executive incentive plan was established by the Compensation Committee in 1999. This Executive Incentive Bonus Plan (the “EIBP”), is a cash based incentive bonus program. The purpose of this plan is to align executive officers’ as well as key employees’ performance with Amkor’s objectives and operating income and revenue growth. The EIBP establishes performance targets for each of these three measures, and determines, by individual, the targeted bonus level for performance.

      Most of our employees are eligible to participate in a cash bonus program which is proportional to corporate profitability. Annually, a percentage of our profit before taxes is allocated to the profit sharing pool. This allocation is distributed as a percentage of employees’ base pay, to eligible participants within our company.

      Long-term incentive compensation currently consists solely of stock options. The Compensation Committee is responsible for the administration of our stock option program. Option grants are made under the

1998 Stock Option Plan, as amended, at the fair market price on the date of grant and expire up to ten years after the date of the grant. The Compensation Committee believes that stock options are a competitive necessity in the electronics industry.

      As a general rule, the Compensation Committee believes that a certain portion of the compensation package for all Executive Officers should be based on long-term incentives.

REPORT OF THE AUDIT COMMITTEE

      The role of the Audit Committee is to review Amkor’s financial reporting process on behalf of the Board of Directors. The Audit Committee is comprised solely of independent directors, as defined in the NASDAQ listing standards, and it operates under a written charter adopted by the Board of Directors. The Audit Committee reviews and reassesses the adequacy of the Audit Committee Charter on an annual basis.

      The Audit Committee’s overall responsibility is one of oversight. Management is responsible for Amkor’s consolidated financial statements as well as for maintaining effective internal controls over financial reporting, disclosure controls and procedures, compliance with laws and regulations and applicable ethical business standards. The independent accountants are responsible for performing audits of Amkor’s consolidated financial statements, management’s assessment of Amkor’s internal control over financial reporting and of the effectiveness of such internal controls in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”) and issuing reports thereon. The Audit Committee met with the independent accountants, with and without management present, to discuss the results of their audits and the overall quality of the Company’s financial reporting.

      In performing its oversight function, the Audit Committee considered and discussed Amkor’s consolidated financial statements and management’s report on internal control over financial reporting with management and the independent accountants. The Audit Committee has also discussed with the independent accountants the matters required to be discussed by Statement of Auditing Standards, as amended, including Statement of Auditing Standards No. 61, Communication with Audit Committees, and the PCAOB standards.

      The Audit Committee discussed with the independent accountants their independence from Amkor and its management and obtained the written disclosures from the independent accountants required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees. The Audit Committee considered whether the provision of non-audit services by Amkor’s independent accountants is compatible with maintaining the independent accountants’ independence. The Audit Committee concluded that the independent accountants are independent from Amkor and its management.

      Based on all of the foregoing, the Audit Committee recommended to the Board of Directors that Amkor’s consolidated financial statements and management’s report on internal control over financial reporting along with the related reports of our independent accountants be included in Amkor’s Annual Report on Form 10-K/ A and be filed with the Securities and Exchange Commission. The Audit Committee also selected PricewaterhouseCoopers LLP as the independent accountants for Amkor for fiscal 2005.

      The foregoing report has been furnished by the following directors and members of the Audit Committee:

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

We subleased a portion of this space, and our 2004 sublease income includes $0.6 million from a company in which certain of our board

members have ownership interests. In the second quarter of 2005, we vacated a substantial portion of the leased space and paid the trusts $710,000 to settle the then-remaining lease obligations associated with that space. We currently lease approximately 2,700 square feet of office space from these trusts.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

      Section 16(a) of the Securities Exchange Act of 1934 requires our officers and directors, and persons who own more than ten percent of a registered class of our equity securities, to file reports of ownership on Form 3 and changes in ownership on Form 4 or 5 with the Securities and Exchange Commission (the “SEC”) and the National Association of Securities Dealers, Inc. Such officers, directors and ten-percent stockholders are also required by SEC rules to furnish Amkor with copies of all forms that they file pursuant to Section 16(a).

      Based solely on our review of the copies of such forms received by us, or written representations from certain reporting persons that no other reports were required for such persons, Amkor believes that all Section 16(a) filing requirements applicable to our officers, directors and ten-percent stockholders were complied with in a timely fashion during 2004, with the exception of one report on Form 4 for each of the non-employee directors. Amkor failed to report, on behalf of directors Winston J. Churchill, Thomas D. George, Gregory K. Hinckley, Juergen Knorr and Jim W. Zug, and former director John B. Neff, a stock option grant that was granted on July 29, 2004. In each case, the required forms were not filed on a timely basis but have since been filed.

PROPOSAL TWO

RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS

      The Audit Committee has approved the appointment of PricewaterhouseCoopers LLP (“PricewaterhouseCoopers”) as our independent accountants for fiscal 2005.

      PricewaterhouseCoopers has served as our independent accountants since 2000. The Board of Directors expects that representatives of PricewaterhouseCoopers will attend the Annual Meeting to make a statement if they desire to do so, and such representatives are expected to be available to answer appropriate questions.

      The following table shows the fees paid or accrued by us for the fiscal years 2004 and 2003.

      Our Audit Committee is required to pre-approve the audit and non-audit services performed by our independent accounting firm, PricewaterhouseCoopers LLP, in accordance with the Amkor Audit and Non-Audit Services Pre-Approval Policy. This policy provides for pre-approval of audit, audit-related, tax services and other services specifically described by the Audit Committee. The policy also provides for the general approval of additional individual engagements, which, if they exceed certain pre-established thresholds, must be separately approved by the Audit Committee. This policy authorizes the Audit Committee to delegate to one or more of its members pre-approval authority with respect to permitted services, provided that any such pre-approval decisions must be reported to the Audit Committee. 100% of the above principal accountant services were approved by the Audit Committee during 2004, which concluded that the provision of such services by PricewaterhouseCoopers LLP was compatible with the maintenance of that firm’s independence in the conduct of its auditing functions.

      We are asking our stockholders to ratify the selection of PricewaterhouseCoopers LLP as our independent accountants. Although ratification is not required by our bylaws or otherwise, the Board is submitting the selection of PricewaterhouseCoopers LLP to our stockholders for ratification as a matter of good corporate practice. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent accounting firm at any time during the year if it determines that such a change would be in the best interests of the company and our stockholders.

REQUIRED VOTE

      The ratification of the selection of PricewaterhouseCoopers requires the affirmative vote of the holders of the majority of shares of Common Stock present or represented and entitled to vote at the Annual Meeting. Abstentions and broker non-votes will be counted as present for purposes of determining whether a quorum is present, and broker non-votes will not be treated as entitled to vote on this matter at the Annual Meeting.

Your Board unanimously recommends a vote FOR the ratification of appointment of

PricewaterhouseCoopers LLP as independent accountants for 2005.
