                    CERTIFICATION OF CHIEF FINANCIAL OFFICER
                       PURSUANT TO 15 U.S.C. SECTION 7241,
      AS ADOPTED PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Jens Meyerhoff, certify that:

    1.   I have reviewed the annual report on Form 10-K/A of FormFactor, Inc.,
         a Delaware corporation, for the period ended December 27, 2003, as
         filed with the Securities and Exchange Commission;

    2.   Based on my knowledge, the annual report does not contain any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements made, in light of the circumstances under which
         such statements were made, not misleading with respect to the period
         covered by the annual report;

    3.   Based on my knowledge, the financial statements, and other financial
         information included in the annual report, fairly present in all
         material respects the financial condition, results of operations and
         cash flows of the registrant as of, and for, the periods presented in
         the annual report;

    4.   The registrant's other certifying officer and I are responsible for
         establishing and maintaining disclosure controls and procedures (as
         defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
         registrant and have:

                  (a) Designed such disclosure controls and procedures, or
                  caused such disclosure controls and procedures to be designed
                  under our supervision, to ensure that material information
                  relating to the registrant, including its consolidated
                  subsidiaries, is made known to us by others within those
                  entities, particularly during the period in which the
                  annual report is being prepared;

                  (b) Evaluated the effectiveness of the registrant's disclosure
                  controls and procedures and presented in the annual report
                  our conclusions about the effectiveness of the disclosure
                  controls and procedures, as of the end of the period covered
                  by the annual report based on such evaluation; and

                  (c) Disclosed in the annual report any change in the
                  registrant's internal control over financial reporting that
                  occurred during the registrant's most recent fiscal quarter
                  that has materially affected, or is reasonably likely to
                  materially affect, the registrant's internal control over
                  financial reporting;

    5.   The registrant's other certifying officer and I have disclosed, based
         on our most recent evaluation of internal control over financial
         reporting, to the registrant's auditors and the audit committee of the
         registrant's board of directors:

                  (a) All significant deficiencies and material weaknesses in
                  the design or operation of internal control over financial
                  reporting which are reasonably likely to adversely affect the
                  registrant's ability to record, process, summarize and report
                  financial information; and

                  (b) Any fraud, whether or not material, that involves
                  management or other employees who have a significant role in
                  the registrant's internal control over financial reporting.
