                       7.75% Senior Notes due May 15, 2013

THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE
GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL
OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES
EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED
PURSUANT TO SECTION 2.07 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE
EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE INDENTURE,
(III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT
TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO
A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.

      Capitalized terms used herein shall have the meanings assigned to them in
the Indenture referred to below unless otherwise indicated.

      1.    Interest. Amkor Technology, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at
7.75% per annum from May 8, 2003 until maturity. The Company will pay interest
semi-annually in arrears on May 15 and November 15 of each year, or if any such
day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"). Interest on the Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from the
date of issuance; provided that if there is no existing Default in the payment
of interest, and if this Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be November 15, 2003. The Company shall
pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is 1% per annum in excess of the rate then in effect; it
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace periods) from time to time on demand at the same rate to the
extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

      2.    Method of Payment. The Company will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the May 1 or November 1 next preceding the Interest
Payment Date, even if such Notes are canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. The Notes will be payable as to
principal and premium, if any, and interest at the office or agency of the
Company maintained for such purpose within or without the City and State of New
York, or, at the option of the Company, payment of interest may be made by check
mailed to the Holders at their addresses set forth in the register of Holders,
and provided that payment by wire transfer of immediately available funds will
be required with respect to principal of and interest and premium on, all Global
Notes and all other Notes the Holders of which shall have provided wire transfer
instructions to the Company or the Paying Agent. Such payment shall be in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts.

      3.    Paying Agent and Registrar. Initially, U.S. Bank National
Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.
<PAGE>
      4.    Indenture. The Company issued the Notes under an Indenture dated as
of May 8, 2003 ("Indenture") between the Company and the Trustee. The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the indenture shall govern and be
controlling. The Notes are obligations of the Company limited to $425 million in
aggregate principal amount.

      5.    Optional Redemption.

      The Notes will not be redeemable at the option of the Company prior to May
15, 2008. Starting on that date, the Company may redeem all or any portion of
the Notes, at once or over time, after giving the required notice as provided in
this Article 3. The Notes may be redeemed at the redemption prices set forth
below, plus accrued and unpaid interest, if any, to the redemption date (subject
to the right of holders of record on the relevant record date to receive
interest due on the relevant interest payment date). The following prices are
for Notes redeemed during the 12-month period commencing on May 15 of the years
set forth below, and are expressed as percentages of principal amount:

<TABLE>
<CAPTION>
      Redemption Year                                    Price
      ---------------                                    -----
<S>                                                      <C>
      2008............................................   103.875%
      2009............................................   102.583%
      2010............................................   101.292%
      2011 and thereafter.............................   100.000%
</TABLE>

      6.    No Mandatory Redemption.

      Except as set forth in paragraph 7 below, the Company shall not be
required to make mandatory redemption payments with respect to the Notes.

      7.    Repurchase at Option of Holder.

      (a) If there is a Change of Control, the Company shall be required to make
an offer (a "Change of Control Offer") to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest thereon, if any, to the date of purchase (the "Change of Control
Payment"). Within 30 days following any Change of Control, the Company shall
mail a notice to each Holder setting forth the procedures governing the Change
of Control Offer as required by the Indenture.

      (b) If the Company or a Subsidiary consummates any Asset Sales, within
five days of each date on which the aggregate amount of Excess Proceeds exceeds
$10 million, the Company shall commence an offer to all Holders of Notes and all
holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to Section 4.10 of the Indenture (as "Asset Sale Offer")
pursuant to Section 3.09 of the Indenture to purchase the maximum principal
amount of Notes and such pari passu Indebtedness that may be purchased out of
the Excess Proceeds at an offer price in cash in an amount equal to 100% of the
principal amount thereof plus accrued and unpaid interest thereon, if any, to
the date fixed for the closing of such offer, in accordance with the procedures
set forth in the Indenture. To the extent that the aggregate amount of Notes and
such pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less
than the Excess Proceeds, the Company (or such Subsidiary) may use such
deficiency for any purpose not otherwise prohibited by the Indenture. If the
aggregate principal amount of Notes surrendered by Holders thereof plus the
amount of any pari passu Indebtedness surrendered by the
<PAGE>
holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes to be purchased on a pro rata basis. Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the
Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse of the Notes.

      8.    Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

      9.    Persons Deemed Owners. The registered Holder of a Note may be
treated as its owner for all purposes.

      10.   Amendment, Supplement and Waiver. Subject to certain exceptions, the
Indenture, the Note Guarantees or the Notes may be amended or supplemented with
the consent of the Holders of at least a majority in principal amount of the
then outstanding Notes voting as a single class, and any existing default or
compliance with any provision of the Indenture, the Note Guarantees or the Notes
may be waived with the consent of the Holders of a majority in principal amount
of the then outstanding Notes voting as a single class. Without the consent of
any Holder of a Note, the Indenture, the Note Guarantees or the Notes may be
amended or supplemented to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Company's or Guarantor's obligations
to Holders of the Notes in case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of the Notes
or that does not adversely affect the legal rights under the Indenture of any
such Holder, to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act or to
allow any Guarantor to execute a supplemental indenture to the Indenture and/or
a Note Guarantee with respect to the Notes.

      11.   Defaults and Remedies. Events of Default include: (i) default for 30
days in the payment when due of interest on the Notes; (ii) default in payment
when due of principal of or premium, if any, on the Notes when the same becomes
due and payable at maturity, upon redemption (including in connection with an
offer to purchase) or otherwise, (iii) failure by the Company to comply with
Section 4.10 or 4.14 of the Indenture; (iv) failure by the Company for 60 days
after notice to the Company by the Trustee or the Holders of at least 25% in
principal amount of the Notes then outstanding voting as a single class to
comply with certain other agreements in the Indenture or the Notes; (v) default
under certain other agreements relating to Indebtedness of the Company which
default is caused by a failure to pay principal of such Indebtedness at the
express maturity thereof or results in the acceleration of such Indebtedness
prior to its express maturity; (vi) certain final judgments for the payment of
money that remain undischarged for a period of 60 days; and (vii) certain events
of bankruptcy or insolvency with respect to the Company or any of its
Significant Subsidiaries. If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
outstanding Notes may declare all the Notes to be due and payable.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, all outstanding Notes will become
due and payable without further action or notice. Holders may not enforce the
Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of
<PAGE>
the then outstanding Notes may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders of the Notes notice of any
continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may on
behalf of the Holders of all of the Notes waive any existing Default or Event of
Default and its consequences under the Indenture except a continuing Default or
Event of Default in the payment of interest on, or the principal of, the Notes.
The Company is required to deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Company is required upon becoming aware
of any Default or Event of Default, to deliver to the Trustee a statement
specifying such Default or Event of Default.

      12.   DESIGNATED SENIOR DEBT. This Note shall be "Designated Senior Debt"
for purposes of the indentures governing the Company's 5.75% convertible
subordinated notes due 2006, 5.00% convertible subordinated notes due 2007 and
the Senior Subordinated Notes.

      13.   GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL
GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT
THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

      14.   Trustee Dealings with Company. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

      15.   No Recourse Against Others. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

      16.   Authentication. This Note shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

      17.   Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

      18.   CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.
