                   AEHR TEST SYSTEMS REPORTS FOURTH QUARTER
                       AND FISCAL 2003 RESULTS

Fremont, CA (July 22, 2003) -- Aehr Test Systems (Nasdaq: AEHR) today
announced financial results for the fourth quarter and fiscal year ended May
31, 2003.

Net sales for the fourth quarter of fiscal 2003 were $4.6 million, an
increase of 31 percent from $3.5 million for the fourth quarter of fiscal
2002.  Net sales for the fourth quarter increased by 15 percent to $4.6
million from $4.0 million in the third quarter of fiscal 2003.  The operating
loss for the fourth quarter of fiscal 2003 was $864,000, representing a 28
percent reduction from the operating loss of $1.2 million in the fourth
quarter of fiscal 2002 and a 20 percent reduction from the operating loss of
$1.1 million in the third quarter of fiscal 2003.  Net loss for the fourth
quarter of fiscal 2003 was $677,000, or $0.09 per share, compared with a net
loss of $3.1 million, or $0.43 per share, in the same quarter of fiscal 2002.
The net loss for the fourth quarter of fiscal 2002 included a $2.5 million,
or $0.34 per share, non-cash charge related to the deferred tax assets
valuation allowance.

"We are very pleased with our fourth quarter net sales performance, which
marked the second sequential quarter of double-digit growth," said Rhea
Posedel, chairman and chief executive officer of Aehr Test.  "Net sales
reached their highest quarterly level of the last two years, during the
protracted semiconductor industry downturn.  The growth was primarily driven
by an increase in demand for our core burn-in and test systems, a trend we
began seeing in the third quarter."

"During the quarter, we achieved a major product development goal," said C.J.
Meurell, president and chief operating officer of Aehr Test.  "We made
significant progress in the development of our FOX full wafer burn-in and
test system and completed another key development milestone, which resulted
in the recognition of $400,000 in net sales in the fourth quarter.  Many IC
manufacturers are interested in our FOX products because of the systems'
innovative capability to parallel test and burn-in devices at the wafer
level, which they anticipate will reduce test cost, decrease cycle time and
eliminate process steps.  We believe the FOX technology can be used in a wide
variety of applications, expanding our addressable market and creating new
revenue opportunities.  We expect the FOX products to fuel our growth over
the long-term."

Net sales for the year ended May 31, 2003 were $15.1 million, a 20 percent
increase from net sales of $12.6 million in fiscal 2002.  The operating loss
for fiscal 2003 was $4.7 million compared with the operating loss of $4.5
million for fiscal 2002.  Net loss for fiscal 2003 was $4.5 million, or $0.63
per share, compared with a net loss of $5.3 million, or $0.74 per share, in

                                    -more-


fiscal 2002.  Net loss for fiscal 2002 included the $2.5 million non-cash
charge related to the deferred tax assets valuation allowance.

As of May 31, 2003, the Company had no debt outstanding; its cash, short-term
investments and long-term investments totaled $11.4 million, and its book
value was $3.54 per share.

"Despite this extremely difficult market environment, we are very proud of our
accomplishments in fiscal 2003," commented Posedel.  "We grew revenues 20
percent on an annual basis and ended fiscal 2003 with an order backlog of $5.1
million compared with $3.9 million at the end of the prior fiscal year.  We
also made tremendous strides in new product development.  With the successful
completion of two development milestones for the FOX product line, our efforts
are beginning to bear fruit."

Posedel concluded, "The outlook for the semiconductor equipment sector is
still cloudy, and we believe that our net sales in the first quarter of
fiscal 2004 may be down somewhat compared to the fourth quarter of fiscal
2003.  Despite limited visibility, we are confident that our strategy will
continue to enable us to weather this downturn.  We remain committed to our
product development efforts and will continue to fund this investment with
our solid, debt-free balance sheet.  We are optimistic about the potential of
the FOX products and the long-term future of Aehr Test."
