STATS ChipPAC Ltd.

Dear Sirs,


1.   We have acted as Singapore legal advisers to STATS ChipPAC Ltd. (the
     "Company"), a company organised under the laws of Singapore, in connection
     with a registration statement on Form S-8 as Post-Effective No. 1 to a
     registration statement on Form F-4 to be filed by the Company with the
     Securities and Exchange Commission ("SEC") in the United States on August
     24, 2004 (the "Registration Statement"), for the registration under the
     United States Securities Act of 1933, as amended, of up to 80.2 million
     ordinary shares of S$0.25 each in the capital of the Company (the
     "Shares"), directly or in the form of American Depositary Shares, issuable
     upon exercise of options ("Options") issued or issuable pursuant to the
     STATS ChipPAC Ltd. Substitute Share Purchase and Option Plan and the STATS
     ChipPAC Ltd. Substitute Equity Incentive Plan (collectively, the "STATS
     ChipPAC Substitute Option Plans").

2.   We have examined the following documents:

     (a)  a copy of each of the STATS ChipPAC Substitute Option Plans;

     (b)  a draft of the Registration Statement;

     (c)  copies of the Memorandum of Association and Articles of Association of
          the Company, the Certificate of Incorporation of the Company, the
          Certificate of Incorporation on Conversion to a public company of the
          Company;

     (d)  copies of the a certified true extract of the resolutions in writing
          of the Board of Directors of the Company (the "Board Resolutions")
          passed on 11 June 2004 and a certified true extract of the minutes of
          the extraordinary general meeting of the Company held on 4 August 2004
          (the "Shareholders' Resolutions"), inter alia, approving the STATS
          ChipPAC Substitute Option Plans and authorising the issuance of the
          Options pursuant to the STATS ChipPAC Substitute Option Plans and the
          issuance of Shares upon exercise of such Options; and

     (e)  such records of the corporate proceedings of the Company as we have
          deemed relevant and such other certificates, records and documents as
          we deemed necessary for the purposes of this opinion.




3.   We have assumed:

     (a)  the genuineness of all signatures, seals and chops (if any) on all
          documents and the completeness, and the conformity to original
          documents, of all copies submitted to us;

     (b)  that copies of the Memorandum and Articles of Association and the
          Certificate of Incorporation of the Company and the Certificate of
          Incorporation on Conversion to a public company of the Company
          submitted to us for examination are true, complete and up-to-date
          copies;

     (c)  the conformity to the original documents of all documents produced to
          us as copies and the authenticity of the original documents, which or
          copies of which have been submitted to us;

     (d)  that copies of the Board Resolutions and the Shareholders' Resolutions
          submitted to us for examination are true, complete and up to date
          copies; and

     (e)  that the Board Resolutions and the Shareholders' Resolutions have not
          been rescinded or modified and they remain in full force and effect
          and that no other resolution or other action has been taken which may
          affect the validity of the Board Resolutions or the Shareholders'
          Resolutions.

4.   Based upon and subject to the foregoing, and assuming that the total issued
     and paid-up share capital of the Company consequent upon the issue of the
     Shares from time to time will not exceed the authorised share capital of
     the Company at any time, and there shall be subsisting a valid authority
     given pursuant to Section 161 of the Companies Act, Chapter 50 of Singapore
     in respect of the issue of Shares from time to time, we are of the opinion
     that the Shares will be duly authorised and, when and to the extent Options
     are issued pursuant to the STATS ChipPAC Substitute Option Plans and
     exercised in accordance with the terms of the STATS ChipPAC Substitute
     Option Plans and upon receipt of the approval of the Board of Directors of
     the Company or a committee thereof for the allotment and issue of the
     Shares and, upon the issue of share certificates representing the Shares in
     accordance with the Articles of Association of the Company against payment
     for the Shares, the Shares will be validly issued, fully paid and
     non-assessable. For the purposes of this opinion we have assumed that the
     term "non-assessable" in relation to the Shares to be issued means under
     Singapore law that holders of such Shares, having fully paid up all amounts
     due on such Shares as to nominal amount and premium thereon, are under no
     further personal liability to contribute to the assets or liabilities of
     the Company in their capacities purely as holders of such Shares.

5.   We hereby consent to the filing of this letter as an exhibit to the
     Registration Statement. In giving such consent, we do not thereby admit
     that we are in the category of persons whose consent is required under
     Section 7 of the United States Securities Act of 1933, as amended or the
     rules and regulations of the SEC thereunder.





Yours faithfully
