RE: REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

We have examined the Registration Statement on Form S-1 (the
"Registration Statement") to be filed by Amkor Technology, Inc. (the "Company")
with the Securities and Exchange Commission on or about April 30, 1998 pursuant
to Section 462(b) of the Securities Act of 1933, as amended (the "Registration
Statement"), in connection with the registration under the Securities Act of
1933, as amended, of (i) up to an aggregate of $34,500,000 principal amount of
convertible subordinated notes due 2003 (the "Notes") and (ii) Common Stock
issuable upon conversion of the Notes (the "Underlying Common"). The Notes are
to be issued pursuant to an Indenture (the "Indenture"), the form of which has
been filed as an exhibit to the Registration Statement, to be entered into
between the Company and State Street Bank and Trust Company, as Trustee (the
"Trustee"). The Shares and the Notes are to be sold pursuant to an Underwriting
Agreement (the "Underwriting Agreement") in substantially the form filed as an
exhibit to the Registration Statement. The Notes are to be issued in the form of
Note included in the Indenture.

We have examined instruments, documents and records which we deemed
relevant and necessary for the basis of our opinion hereinafter expressed. In
such examination, we have assumed (a) the authenticity of original documents
and the genuineness of all signatures, (b) the conformity to the originals of
all documents submitted to us as copies and (c) the truth, accuracy and
completeness of the information, representations and warranties contained in
the records, documents, instruments and certificates we have reviewed.

Based on such examination, we are of the opinion that:

(i) The Notes are legal, valid and binding obligations of the Company,
entitled to the benefits of the Indenture.

(ii) The Underlying Common has been legally and validly authorized,
and when issued and delivered in accordance with the terms of the Indenture,
will be duly and validly issued, fully paid and non-assessable.

Our opinion that any document is legal, valid and binding is qualified
as to:

(A) Limitations imposed by bankruptcy, insolvency, reorganization,
arrangement, fraudulent conveyance, moratorium or other laws relating to or
affecting the rights of creditors generally;

(B) General principles of equity, including without limitation,
concepts of materiality, reasonableness, good faith and fair dealing, and the
possible unavailability of specific performance or injunctive relief, and
limitations of rights of acceleration regardless of whether such enforceability
is considered in a proceeding in equity or at law.

We consent to the use of this opinion as an exhibit to the Registration
Statement, including the prospectus constituting a part thereof, and further
consent to the use of our name wherever it appears in the Registration Statement
and any amendments thereto.

Very truly yours,

WILSON SONSINI GOODRICH & ROSATI
