    RE:  REGISTRATION STATEMENT ON FORM S-8 -- 1998 EMPLOYEE STOCK
         PURCHASE PLAN, 1998 STOCK PLAN AND 1998 STOCK OPTION PLAN FOR
         FRENCH EMPLOYEES

Ladies and Gentlemen:

We have examined the Registration Statement on Form S-8 (the "Registration
Statement") to be filed by Amkor Technology, Inc., a Delaware corporation (the
"Company" or "you"), with the Securities and Exchange Commission on or about
October 29, 2002, in connection with the registration under the Securities Act
of 1933, as amended (the "Act"), of (a) an aggregate of 482,937 additional
shares (the "ESPP Shares") of your Common Stock reserved for issuance pursuant
to the Company's 1998 Employee Stock Purchase Plan (the "Purchase Plan"); (b) an
aggregate of 3,365,004 additional shares (the "Plan Shares") of your Common
Stock reserved for issuance pursuant to the Company's 1998 Stock Plan (the
"Plan"); and (c) an aggregate of 203,983 additional shares (the "French Plan
Shares") of your Common Stock reserved for issuance pursuant to the Company's
1998 Stock Option Plan for French Employees (the "French Plan"). As your legal
counsel, we have reviewed the actions proposed to be taken by you in connection
with the proposed sale and issuance of the ESPP Shares, the Plan Shares and the
French Plan Shares by the Company under the Purchase Plan, the Plan and the
French Plan, respectively.

It is our opinion that, upon completion of the actions being taken, or
contemplated by us as your counsel to be taken, by you prior to the issuance of
the ESPP Shares pursuant to the Registration Statement, and assuming that the
ESPP Shares are issued in accordance with the provisions of the Purchase Plan,
the ESPP Shares will be legally and validly issued, fully paid and
nonassessable. Further, it is our opinion that, upon completion of the actions
being taken, or contemplated by us as your counsel to be taken, by you prior to
the issuance of the Plan Shares pursuant to the Registration Statement, and
assuming that the Plan Shares are issued in accordance with the provisions of
the Plan, the Plan Shares will be legally and validly issued, fully paid and
nonassessable. Further, it is our opinion that, upon completion of the actions
being taken, or contemplated by us as your counsel to be taken, by you prior to
the issuance of the French Plan Shares pursuant to the Registration Statement,
and assuming that the French Plan Shares are issued in accordance with the
provisions of the French Plan, the French Plan Shares will be legally and
validly issued, fully paid and nonassessable.

We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement and any subsequent amendment thereto.

                                Very truly yours,

                                /s/ Wilson Sonsini Goodrich & Rosati
