(to Prospectus dated October 4, 2001)                        Cusip No. 501242AJ0

                                  $125,000,000

                       KULICKE AND SOFFA INDUSTRIES, INC.

               5 1/4% Convertible Subordinated Notes due 2006 and
             the Common Stock issuable upon conversion of the Notes

                              --------------------

         The following table supplements and amends the information set forth on
pages 31 to 33 in the prospectus under Selling Securityholders with respect to
the selling securityholders and the principal amount of notes beneficially owned
by such selling securityholders that may be offered and sold pursuant to the
prospectus dated October 4, 2001. This prospectus supplement is not complete
without, and may not be delivered or utilized except in connection with, the
prospectus.

* Less than 1%

         (1)      Assumes conversion of all of the holder's notes at a
                  conversion ratio of 50.6401 shares per $1,000 principal amount
                  of notes. However, this conversion ratio will be subject to
                  further adjustment as described under "Description of
                  Notes-Conversion of Notes." As a result, the amount of common
                  stock issuable upon conversion of the notes may increase or
                  decrease in the future.

         (2)      Calculated based on Rule 13d-3(d)(i) of the Exchange Act using
                  49,034,316 shares of common stock outstanding as of September
                  14, 2001. In calculating this amount, we treated as
                  outstanding the number of shares of common stock issuable upon
                  conversion of all of that particular holder's notes. However,
                  we did not assume the conversion of any other holder's notes.

         Because the selling securityholders listed above and in the prospectus
under the caption Selling Securityholders may, pursuant to the prospectus, as
supplemented, offer all or some portion of the notes, no estimate can be given
as to the amount of notes that will be held by the selling securityholders upon
termination of any such sales.

         Furthermore, the selling securityholders identified in the table set
forth in the prospectus under the caption Selling Securityholders may have sold,
transferred or otherwise disposed of all or a portion of their notes or common
stock since the date on which they provided us with information regarding their
notes or common stock, and we have not made any independent inquiries as to the
foregoing.

         Unless otherwise noted, all information provided in this prospectus
supplement is as of December 21, 2001.
