Exhibit 99.1


     Electro Scientific Industries Announces Executive Termination


    PORTLAND, Ore.--(BUSINESS WIRE)--June 9, 2003--Electro Scientific
Industries, Inc. (Nasdaq:ESIOE) announced today that it has terminated
the employment of James Dooley.
    On April 15, 2003, ESI's Board of Directors placed Mr. Dooley,
then its Chief Executive Officer, on paid administrative leave pending
further investigation. Based on the Audit Committee's ongoing
investigation, the Board of Directors today terminated Mr. Dooley's
employment with the Company.
    On March 20, 2003 and April 15, 2003, ESI announced that it will
restate its financial results for the first and second quarters of
fiscal 2003 and revise its preliminary results for the third quarter
of fiscal 2003. ESI also stated that its Audit Committee was
conducting a thorough review of all matters identified in the
restatement.
    The Audit Committee is continuing its investigation of the items
in the previously announced restatement and is also reviewing the
Company's application of SAB 101 to revenue transactions. ESI
currently believes that its restatement will change the timing or
defer the recognition of revenue for a substantial number of
transactions recorded during fiscal 2003 and prior periods.

    This press release includes forward-looking statements, which are
subject to the Safe Harbor provisions created by the Private
Securities Litigation Reform Act of 1995. These statements include
statements about the audit committee's ongoing review of the Company's
financial statements, and the potential restatement of revenues and
expenses recognized in prior periods. Such statements are subject to a
number of risks and uncertainties that may cause actual results to
differ materially from the forward-looking statements. The Company may
discover new information and determine that further accounting
adjustments should be made, which may materially increase the amount
of the adjustment that the Company currently believes it will record
for the first, second and third quarters of fiscal 2003, or may
require a restatement of other prior fiscal periods. Other risks are
discussed in more detail in the Company's Annual Report on Form 10-K
and interim reports on Form 10-Q.
