(1)       prepare, execute in the undersigned's name and on the undersigned's
behalf, and submit to the U.S. Securities and Exchange Commission (the "SEC) a
Form ID, including amendments thereto, and any other documents necessary or
appropriate to obtain codes and passwords enabling the undersigned to make
electronic filings with the SEC of reports required by Section 16 (a) of the
Securities Exchange Act of 1934 or any rule or regulation of the SEC;

(2)       execute for and on behalf of the undersigned, in the undersigned's
capacity as an officer and/or director of Cohu, Inc. (the "Company"), Forms 3,
4, and 5 in accordance with Section 16(a) of the Securities Exchange Act of 1934
and the rules thereunder, and any other forms or reports the undersigned may be
required to file in connection with the undersigned's ownership, acquisition, or
disposition of securities of the Company;

(3)       do and perform any and all acts for and on behalf of the undersigned
which may be necessary or desirable to complete and execute any such Form 3, 4,
or 5, or other form or report, and timely file such form or report with the
United States Securities and Exchange Commission and any stock exchange or
similar authority; and

(4)       take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit to,
in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and shall
contain such terms and conditions as such attorney-in-fact may approve in such
attorney-in-fact's discretion.

           The undersigned hereby grants to each such attorney-in-fact full
power and authority to do and perform any and every act and thing whatsoever
requisite, necessary, or proper to be done in the exercise of any of the rights
and powers herein granted, as fully to all intents and purposes as the
