Aehr Test Systems Announces ABTS(TM) System Order From Chinese Semiconductor Foundry

Aehr Test Systems Announces ABTS(TM) System Order From Chinese Semiconductor

FREMONT, Calif., Sept. 26, 2013 (GLOBE NEWSWIRE) -- Aehr Test Systems
(Nasdaq:AEHR), a worldwide supplier of semiconductor test and burn-in
equipment, today announced it has received an order for an ABTS Burn-in and
Test System from a Chinese semiconductor foundry. The order includes a down
payment for this specialized hot/cold configuration.Shipment is expected
before the end of Aehr Test's third quarter of fiscal 2014.

"We are pleased to receive this order from a new customer in China," said Mark
Allison, vice president of sales at Aehr Test Systems."This order from a
semiconductor foundry shows how increased reliability and quality needs for
automotive and mobility devices are driving new requirements in the test and
burn-in market.Our selection was based on our ability to provide a
state-of-the-art system to fill their needs both now and for the foreseeable
future, and we were able to provide that to them at an attractive price."

The order is from a specialized semiconductor foundry with a strong focus on
high quality services and advanced value-added technologies, including
embedded nonvolatile memory, high voltage and low leakage processes. The ABTS
system will be used in the qualification and on-going process monitoring of
various types of memories, including Flash and SRAM.Qualification tests
typically utilize a high-temperature operating life (HTOL) test, where failure
mechanisms are accelerated by burning-in the devices for 1000 hours to confirm
that the basic design and fabrication process of a device will meet the
reliability targets over an extended period of normal use.On-going process
monitoring involves selecting samples from production lots and burning them in
at high or low temperature to ensure that the process continues to hit its
reliability targets.

"In this case, the system will also perform a low-temperature operating life
(LTOL) test, where the devices are subjected to temperatures as low as -40C
for an extended period," Allison continued."In addition to being a more
rigorous screen for various failure mechanisms, LTOL is important for
identifying failure modes for automotive applications, since automobiles are
often subjected to extremely low temperatures."

The ABTS family of products is based on a new hardware and software platform
that is designed to address not only today's devices, but also future devices
for many years to come. It can test and burn-in both logic and memory devices,
including resources for high pin-count devices and configurations for
high-power and low-power applications. The ABTS system can be configured with
up to 72 burn-in boards with up to 320 I/O channels each and 32M of test
vector memory per channel. The ABTS offers the option of high voltage Device
Power Supplies configurable with programmable voltage ranges to 60 or 230
volts, which are needed for automotive and power-line applications.The ABTS
system is optimized for use with the Sensata iSocket* and VTR Thermal
Management Technologies, which provide a scalable cost-effective solution
using individual device temperature control for ICs up to 75 watts or more.
Individual temperature control enables high-power devices with a broad range
of power dissipation to be burned-in simultaneously in a single burn-in
chamber while maintaining a precise device temperature. The ABTS system also
uses N+1 redundancy technology and hot-swap capability for many key components
in the system to maximize system uptime.

About Aehr Test Systems

Headquartered in Fremont, California, Aehr Test Systems is a worldwide
provider of test systems for burning-in and testing logic and memory
integrated circuits and has an installed base of more than 2,500 systems
worldwide. Increased quality and reliability needs of the Automotive and
Mobility integrated circuit markets are driving additional test requirements,
capacity needs and opportunities for Aehr Test products in package and wafer
level test. Aehr Test has developed and introduced several innovative
products, including the ABTS and FOX^TM families of test and burn-in systems
and the DiePak^® carrier. The ABTS system is used in production and
qualification testing of packaged parts for both lower-power and higher-power
logic as well as all common types of memory devices. The FOX system is a full
wafer contact test and burn-in system used for burn-in and functional test of
complex devices, such as leading-edge memories, digital signal processors,
microprocessors, microcontrollers and systems-on-a-chip. The DiePak carrier is
a reusable, temporary package that enables IC manufacturers to perform
cost-effective final test and burn-in of bare die. For more information,
