NPTest Holding, LLC, a Delaware limited liability corporation, Francisco Partners, L.P., a Delaware limited liability partnership and Francisco Partners GP, LLC, a Delaware limited liability company (together, the “Reporting Persons”), hereby amend and supplement the statement on Schedule 13D previously filed by them with respect to the Common Stock, par value $0.001 per share (the “Shares”), of Credence Systems Corporation, a Delaware corporation (the “Issuer”), beneficially owned by them. Except as amended and supplemented hereby, the statement on Schedule 13D, as heretofore amended and supplemented, remains in full force and effect.

On June 2, 2005 NPTest Holding, LLC sold 5,000,000 Shares at a price of $8.14 per share to Citigroup Global Markets Inc. (the “Broker”) in a “broker’s transaction” as that term is defined by Rule 144 promulgated under the Securities Act of 1933, as amended.

At the completion of the sale of the 5,000,000 Shares to the Broker, NPTest Holding, LLC acquired 6,657,400 Shares pursuant to the conversion of 66,574 shares of non-voting convertible stock of the Issuer.

As of the date of the filing of this statement, the Reporting Persons beneficially own 10,303,600 Shares of the Issuer, representing approximately 10.50% of the Issuer’s outstanding Shares. The percentage of the Issuer’s outstanding Common Stock reported herein as beneficially owned by the Reporting Person is based on 98,127,076 Shares of the Issuer outstanding at June 3, 2005.

After reasonable inquiry and to the best of knowledge and belief of the undersigned, the undersigned certifies that the information set forth in this statement is true, complete and correct.
