POWER OF ATTORNEY
       The undersigned hereby constitutes and appoints each of Charmaine Mesina and Mary Zeigler, signing singly, the
undersigned's true and lawful attorney-in-fact to:

                (1) execute for and on behalf of the undersigned, in the undersigned's capacity as a director and
officer of Applied Materials, 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;
                (2) 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, complete and execute any amendment(s) thereto, and
timely file such form with the United States Securities and Exchange Commission and any stock exchange or similar
authority; and
                (3) 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 undersigned might or could
do if personally present, with full power of substitution or revocation, hereby ratifying and confirming all that
such attorney-in-fact, or such attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this power of attorney and the rights and powers herein granted. The undersigned acknowledges
that the foregoing attorneys-in fact, in serving in such capacity at the request of the undersigned, are not
assuming, nor is the Company assuming, any of the undersigned's responsibilities to comply with Section 16 of
the Securities Exchange Act of 1934.
                This Power of Attorney shall remain in full force and effect until the undersigned is no

in securities issued by the Company, unless earlier revoked by the undersigned in a signed writing delivered
to the Company's Secretary.
                IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be executed as of
this 5th day of September, 2002.
