                                 PROXY STATEMENT
                                 ---------------

                         ANNUAL MEETING OF SHAREHOLDERS

      This  Proxy  Statement  is  being  furnished  to  the  Shareholders   (the
"Shareholders") of Aehr Test Systems, a California  corporation (the "Company"),
in connection with the solicitation of proxies by the Board of Directors for use
at the Annual Meeting of Shareholders  (the "Annual  Meeting") of the Company to
be held on October 17, 2002 and at any adjournments thereof.

      At the Annual Meeting, the Shareholders will be asked:

      1.    To elect five directors.

      2.    To  ratify  the  selection  of  PricewaterhouseCoopers  LLP  as  the
            Company's independent  accountants for the fiscal year ended May 31,
            2003.

      3.    To  transact  such other  business as may  properly  come before the
            Annual Meeting or any adjournments of the Annual Meeting.

      The Board of  Directors  has fixed the close of business on  September  4,
2002 as the record date for the  determination  of the  holders of Common  Stock
entitled to notice of and to vote at the Annual Meeting.  Each such  Shareholder
will be entitled  to one vote for each share of Common  Stock  ("Common  Share")
held on all matters to come before the Annual  Meeting and may vote in person or
by proxy authorized in writing.

      This Proxy  Statement and the  accompanying  form of proxy are first being
sent to holders of the Common Shares on or about September 27, 2002.

                               THE ANNUAL MEETING

Date, Time and Place

      The Annual  Meeting  will be held on October 17, 2002 at 4:00 p.m.,  local
time, at 400 Kato Terrace, Fremont, California 94539.

General

      The Company's  principal  office is located at 400 Kato Terrace,  Fremont,
California 94539 and its telephone number is (510) 623-9400.

Record Date and Shares Entitled to Vote

      Shareholders  of record at the close of business on September 4, 2002 (the
"Record Date") are entitled to notice of and to vote at the Annual  Meeting.  As
of the Record Date, there were 7,183,786 Common Shares  outstanding and entitled
to vote.

Revocability of Proxies

      Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time  before  its use by  delivering  to the  Company a written
notice  of  revocation  or a duly  executed  proxy  bearing  a later  date or by
attending the meeting and voting in person.

Voting and Proxy Solicitation

      Each shareholder  voting for the election of directors may cumulate his or
her  votes,  giving  one  candidate  a number  of votes  equal to the  number of
directors to be elected  multiplied by the number of shares that the shareholder
is  entitled  to  vote,  or  distributing  the  shareholder's  votes on the same
principle among as many candidates as the  shareholder  chooses.  No shareholder
shall be entitled to cumulate  votes for any


                                       1


candidate  unless the  candidate's  name has been properly  placed in nomination
prior to the voting and the  shareholder,  or any other  shareholder,  has given
notice at the meeting prior to the voting of the intention to cumulate votes. On
all other matters, each share has one vote.

      Proxies are being solicited by the Company.  The cost of this solicitation
will be borne by the  Company.  The Company may  reimburse  brokerage  firms and
other persons  representing  beneficial  owners of shares for their  expenses in
forwarding  solicitation material to such beneficial owners. Proxies may also be
solicited  by  certain  of  the  Company's  directors,   officers,  and  regular
employees,  without  additional  compensation,  personally  or by  telephone  or
telegram.

Quorum; Abstentions; Broker Non-Votes

      The required  quorum for the transaction of business at the Annual Meeting
is a majority of the shares of Common Stock issued and outstanding on the Record
Date.  Shares that are voted "FOR,"  "AGAINST"  or "WITHHELD  FROM" a matter are
treated as being  present at the meeting for purposes of  establishing  a quorum
and are also treated as shares  "represented  and voting" (the "Votes  Cast") at
the Annual Meeting with respect to such matter.

      While there is no definitive statutory or case law authority in California
as to the proper treatment of abstentions, the Company believes that abstentions
should be counted for purposes of  determining  both (i) the presence or absence
of a quorum for the  transaction  of business and (ii) the total number of Votes
Cast with respect to a proposal  (other than the election of directors).  In the
absence of controlling  precedent to the contrary,  the Company intends to treat
abstentions in this manner.  Accordingly,  abstentions will have the same effect
as a vote against the proposal.

      Broker  non-votes may be counted for purposes of determining  the presence
or absence of a quorum for the transaction of business,  but will not be counted
for  purposes  of  determining  the  number of Votes  Cast with  respect  to the
proposal on which the broker has  expressly not voted.  Thus, a broker  non-vote
will not affect the outcome of the voting on a proposal.

Deadline for Receipt of Shareholder Proposals for 2003 Annual Meeting

      Shareholders are entitled to present proposals for action at a forthcoming
meeting if they comply with the  requirements of the proxy rules  promulgated by
the Securities and Exchange Commission ("SEC"). Proposals of shareholders of the
Company intended to be presented for  consideration at the Company's 2003 Annual
Meeting of  Shareholders  must be  received by the Company no later than May 31,
2003,  in order that they may be  included  in the proxy  statement  and form of
proxy related to that meeting.

persons  be  nominated  at the  meeting,  the proxy  holders  intend to vote all
proxies received by them in such a manner as will assure the election of as many
nominees  listed below as possible (or, if new nominees have been  designated by
the Board of  Directors,  in such a manner as to elect  such  nominees)  and the
specific  nominees to be voted for will be determined by the proxy holders.  The
Company  is not  aware of any  reason  that any  nominee  will be unable or will

Board Meetings and Committees

      The Board of Directors held a total of four (4) meetings during the fiscal
year ended May 31, 2002. No incumbent  director  during his period of service in
such fiscal year attended fewer than 75% of the aggregate of all meetings of the
Board of  Directors  and the  committees  of the Board upon which such  director
served.  The Board of Directors has two committees,  the Audit Committee and the

      The Compensation Committee of the Board of Directors currently consists of
Messrs. Elder and Rosati. The Compensation Committee held one (1) meeting during
fiscal year 2002. The  Compensation  Committee  reviews and advises the Board of
Directors  regarding all forms of  compensation  to be provided to the officers,
employees, directors and consultants of the Company.

      The  Board of  Directors  has no  nominating  committee  or any  committee
performing such function.

                        REPORT OF THE AUDIT COMMITTEE (1)

      The Audit  Committee of the board of  directors  of the Company  serves as
representatives  of the board for general  oversight of the Company's  financial
accounting and reporting system of internal  control,  audit process and process
for  monitoring  compliance  with laws and  regulations.  The  Audit  Committee,
consisting  of Messrs.  Patel,  Anderson  and Elder,  held three (3) meetings in
fiscal year 2002. Each member is an independent  director in accordance with the
Nasdaq  National  Market  Audit  Committee  requirements.  The  Audit  Committee
evaluates the scope of the annual audit,  reviews audit  results,  consults with
management and the Company's  independent  accountants prior to the presentation
of financial statements to stockholders and, as appropriate, initiates inquiries
into aspects of the Company's financial affairs.

      The  Company's  management  has primary  responsibility  for preparing the
Company's  financial  statements  and  for  the  Company's  financial  reporting
process.  The  Company's  independent  accountants,  PricewaterhouseCoopers  LLP
("PwC"),  are  responsible  for  expressing an opinion on the  conformity of the
Company's  audited  financial   statements  to  generally  accepted   accounting
principles.  The Audit  Committee has reviewed and discussed with management the
audited financial statements for the year ended May 31, 2002. PwC, the Company's
independent  accountants for fiscal year 2002, issued their  unqualified  report
dated July 23, 2002 on the Company's financial statements.

      The Audit Committee has also discussed with PwC the matters required to be
discussed by AICPA Statement on Auditing Standards No. 61,  "Communication  with
Audit Committees." The Audit Committee has also received the written disclosures
and the letter from PwC required by Independence Standards Board Standard No. 1,
"Independence Discussions with Audit Committees," and has conducted a discussion
with PwC  relative  to its  independence.  The Audit  Committee  has  considered
whether  PwC's   provision  of  non-audit   services  is  compatible   with  its
independence. The Audit Committee has an Audit Committee Charter.

      Based  on the  reviews  and  discussions  referred  to  above,  the  Audit
Committee  recommended  to the Board of  Directors of Aehr Test Systems that the
Company's audited financial statements for the fiscal year ended May 31, 2002 be
included in the Annual Report on Form 10-K.

      options at the end of their respective  seven-year terms, as calculated in
      accordance with the rules of the SEC. Each gain is based on an arbitrarily
      assumed  annualized  rate of compound  appreciation of the market price at
      the date of grant of 5% and 10% from the date the  option  was  granted to
      the end of the  option  term.  The 5% and 10%  rates of  appreciation  are
      specified  by the  rules  of the SEC and do not  represent  the  Company's
      estimate or projection of future Common Stock prices. The Company does not
      necessarily  agree that this  method  properly  values an  option.  Actual
      gains, if any, on option exercises are dependent on the future performance
      of the Company's Common Stock and overall market conditions and the timing
      of option exercises, if any.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

General

      In its ordinary course of business,  the Company enters into  transactions
with certain of its directors and officers.  The Company believes that each such
transaction  has been on terms no less favorable for the Company than could have
been obtained in a transaction with an independent third party.

Legal Counsel

      During fiscal 2002, Mario M. Rosati, a member of the Board of Directors of
the  Company,  was also a member of the law firm of Wilson  Sonsini  Goodrich  &
Rosati  ("WSGR").  The Company  retained  WSGR as its legal  counsel  during the
fiscal year.  The Company plans to retain WSGR as its legal counsel again during
fiscal 2003.

Indebtedness of Management

      On October 26, 2000, the Company  received a promissory note signed by Mr.
Gary L. Larson,  the Chief Financial Officer and Vice President of Finance,  for
the principal  sum of $84,000.  This note bore interest at the rate of 6.75% per
annum and was due in full on  February  15,  2002,  unless  repaid on an earlier
date. The funds were used by Mr. Larson to exercise options for 21,000 shares of
common stock of the Company.  This  transaction  was reported on a Form 4 to the
Securities  and Exchange  Commission in fiscal 2001.  This  promissory  note was
subsequently settled during fiscal 2002.

Change of Control Severance Agreement

      On April 23,  2001,  the  Company  has  entered  into a Change of  Control
Severance  Agreement  with Mr.  Christopher  S. Noe and on January 24, 2001, the
Company has entered into Change of Control Severance Agreements with Mr. Carl N.
Buck, Mr. David S. Hendrickson,  Mr. Gary L. Larson, Mr. Carl J. Meurell and Mr.
Rhea J.  Posedel  pursuant  to which  those  executives  would be  entitled to a
payment  in the event of a  termination  of  employment  for  specified  reasons
following  a change of control of the  Company.  For this  purpose,  a change of
control of the Company means a merger or consolidation of the Company, a sale by
the  Company of all or  substantially  all of its  assets,  the  acquisition  of
beneficial  ownership of a majority of the outstanding  voting securities of the
Company by any person or a change in the composition of the Board as a


                                       10


result of which fewer than a majority of the directors are incumbent  directors.
Termination of employment for purposes of these  agreements means a discharge of
the  executive  by the  Company,  other  than  for  specified  causes  including
dishonesty,  conviction of a felony,  misconduct or wrongful  acts.  Termination
also includes  resignation  following the occurrence of an adverse change in the
executive's  position,  duties,  compensation  or work  conditions.  The amounts
payable  under  the  agreements  will  change  from  year to year  based  on the
executive's compensation. In the event of a termination in fiscal 2003 following
a change of control, the amounts payable to Messrs. Buck,  Hendrickson,  Larson,
Meurell and Posedel would be approximately $75,000, $92,000, $130,000,  $159,000
and $218,000, respectively.

Compensation Committee Interlocks and Insider Participation

      The  Compensation  Committee  consists  of Messrs.  Elder and  Rosati.  No
interlocking  relationship  exists between the Company's  Board of Directors and
Compensation  Committee and the board of directors or compensation  committee of
any other company.

                      REPORT OF THE COMPENSATION COMMITTEE
                            OF THE BOARD OF DIRECTORS

      Notwithstanding anything to the contrary set forth in any of the Company's
previous filings under the Securities  Exchange Act of 1933, as amended,  or the
Securities  Act of 1934,  as amended,  that might  incorporate  future  filings,
including this Proxy  Statement,  in whole or in part, the following  report and
the  Performance  Graph shall not be  incorporated  by  reference  into any such
filings.

General

      The  objectives  of the  overall  executive  compensation  program  are to
attract,  retain,  motivate and reward Company  executives  while aligning their
compensation with the achievements of key business  objectives,  maximization of
shareholder value and optimal satisfaction of customers.

      The Compensation Committee is responsible for:

      1.    Determining the specific executive  compensation  methods to be used
            by the  Company  and the  participants  in each  of  those  specific
            programs;

      2.    Determining  the  evaluation  criteria and  timeliness to be used in
            those programs;

      3.    Determining  the  processes  that will be  followed  in the  ongoing
            administration of the programs; and

      4.    Determining their role in the administration of the programs.

      All of the actions take the form of  recommendations  to the full Board of
Directors  where final  approval,  rejection  or  redirection  will  occur.  The
Compensation   Committee  is  responsible  for  administering  the  compensation
programs for all Company officers.  The Compensation Committee has delegated the
responsibility of administering the compensation  programs for all other Company
employees to the Company's officers.

Compensation Vehicles

      Currently, the Company uses the following executive compensation vehicles:

      o     Cash-based  programs:  Base  salary,  Annual  Incentive  Bonus Plan,
            Annual Profit Sharing Plan, and a Sales Incentive  Commission  Plan;
            and

      o     Equity-based  programs:  1996 Incentive  Stock Option Plan, the 1997
            Employee Stock Purchase Plan and the Employee Stock Bonus Plan.

      These  programs  apply to the Chief  Executive  Officer and all  executive
level  positions,  except for the Sales Incentive  Commission  Plan,  which only
includes executives directly responsible for sales activities. Periodically, but
at least once near the close of each fiscal  year,  the  Compensation  Committee
reviews  the  existing  plans and  recommends  those that should be used for the
subsequent year.


                                       11


      The criteria for determining the appropriate salary level, bonus and stock
option grants for the Chief Executive Officer and each of the executive officers
include (a) Company performance as a whole, (b) business unit performance (where
appropriate) and (c) individual performance objectives.  Company performance and
business  unit  performance  are measured  against both  strategic and financial
goals. Examples of these goals are to obtain:  operating profit, revenue growth,
timely new product introduction,  and shareholder value (usually measured by the
Company stock price).  Individual performance is measured to specific objectives
relevant to the individual's position and a specific time frame.

      These criteria are usually related to a fiscal year time period,  but may,
in some cases, be measured over a shorter or longer time frame.

      The processes  used by the  Compensation  Committee  include the following
steps:

      1.    The  Compensation   Committee   periodically   receives  information
            comparing  the  Company's  pay levels to other  companies in similar
            industries,  other leading  companies  (regardless  of industry) and
            competitors.  Primarily national and regional  compensation  surveys
            are used.

      2.    At or near the  start of each  evaluation  cycle,  the  Compensation
            Committee meets with the Chief Executive  Officer to review,  revise
            as needed, and agree on the performance objectives set for the other
            executives.  The Chief Executive Officer and Compensation  Committee
            jointly set the Company objectives to be used. The business unit and
            individual  objectives are formulated jointly by the Chief Executive
            Officer and the  specific  individual.  The  Compensation  Committee
            also,  with the Chief  Executive  Officer,  jointly  establishes and
            agrees on their respective performance objectives.

      3.    Throughout the performance cycle review, feedback is provided by the
            Chief Executive Officer, the Compensation  Committee and full Board,
            as appropriate.

      4.    At the end of the performance  cycle,  the Chief  Executive  Officer
            evaluates  each   executive's   relative   success  in  meeting  the
            performance goals. The Chief Executive Officer makes recommendations
            on  salary,  bonus  and stock  options,  utilizing  the  comparative
            results as a factor.  Also  included in the  decision  criteria  are
            subjective  factors such as teamwork,  leadership  contributions and
            ongoing changes in the business climate. The Chief Executive Officer
            reviews  the  recommendations  and  obtains  Compensation  Committee
            approval.  The  Compensation  Committee also determines the level of
            salary and bonus and the terms of stock option  grants for the Chief
            Executive Officer.

      5.    The final evaluations and compensation  decisions are discussed with
            each  executive  by the  Chief  Executive  Officer  or  Compensation
            Committee, as appropriate.

Policy on Deductibility of Compensation

      Section  162(m) of the  Internal  Revenue  Code of 1986,  as amended  (the
"Code") limits the tax deduction to $1 million for compensation paid to its five
most highly compensated executive officers, unless certain requirements are met.
One requirement is that the Compensation  Committee consists entirely of outside
directors as defined in the Code, and the Company's Compensation Committee meets
this requirement.  Another requirement is that compensation over $1 million must
be based upon  Company  attainment  of  pre-established,  objective  performance
goals. The Company  believes that all compensation  paid to its five most highly
compensated  executive  officers  in  fiscal  2002  is  fully  deductible.   The
Committee's  present  intention  is to comply with the  requirements  of Section
162(m) unless and until the Committee determines that compliance would not be in
the best interest of the Company and its shareholders.

      The Compensation  Committee feels that the  compensation  vehicles used by
the  company,  generally  administered  through the  process as outlined  above,
provide a fair and balanced executive compensation program related to the proper
business issues. In addition, it should be noted that compensation vehicles will
be  reviewed  and,  as  appropriate,  revised in order to attract and retain new
executives in addition to rewarding performance on the job.

Company Performance

      The  following  graph shows a comparison of total  shareholder  return for
holders of the  Company's  Common  Stock from August 15,  1997,  the date of the
Company's initial public offering, through May 31, 2002 compared with The Nasdaq
Stock Market (U.S.) Index and the  Philadelphia  Semiconductor  Index. The graph
assumes  that $100 was invested in the  Company's  Common  Stock,  in the Nasdaq
Stock Market (U.S.) Index and the Philadelphia Semiconductor Index on August 15,
1997, and that all dividends were  reinvested.  The Company  believes that while
total shareholder return can be an important indicator of corporate performance,
the stock prices of semiconductor equipment companies like Aehr Test Systems are
subject to a number of  market-related  factors other than company  performance,
such as competitive announcements, mergers and acquisitions in the industry, the
general  state  of the  economy,  and the  performance  of  other  semiconductor
equipment company stocks.

                         SECURITIES EXCHANGE ACT OF 1934

      Section  16(a)  of the  Exchange  Act  requires  that  directors,  certain
officers of the Company and ten percent  Shareholders  file reports of ownership
and  changes  in  ownership  with  the  SEC  as  to  the  Company's   securities
beneficially  owned by them.  Such  persons  are also  required  by SEC rules to
furnish the Company with copies of all Section 16(a) forms they file.

      Based  solely on its  review  of  copies  of Forms 3 and 4 and  amendments
thereto  furnished  to the  Company  pursuant to Rule  16a-3(e)  and Forms 5 and
amendments  thereto  furnished  to the Company  with  respect to its most recent
fiscal year, and any written representations referred to in Item 405(b)(2)(i) of
Regulation S-K stating that no Forms 5 were required, the Company believes that,
during the fiscal year 2002, all Section 16(a) filing requirements applicable to
the Company's officers,  directors and ten percent  shareholders were filed on a
timely basis.
