Aehr Test Receives $1 Million in DiePak Carrier Orders

MOUNTAIN VIEW, Calif., Dec. 16 -- Aehr Test Systems (NASDAQ:AEHR) announced today that during the past two fiscal quarters it received more than $1 million in orders for its DiePak(R) products, including a follow-on production order from Motorola Inc.(NYSE:MOT) and orders from two new DiePak customers, Sandia National Labs and Rockwell Collins Inc.

DiePak carriers are reusable carriers designed to make temporary contact with unpackaged (bare) semiconductor die. They are the key component of the test and burn-in process for unpackaged die which are then classified as "Known Good Die (KGD)" and used in applications where the individual die packaging is not required.

"DiePak carriers are used by Motorola in a volume production process, enabling us to process bare die with the same quality and reliability as standard packaged die," said Dale Robinson, Assembly Engineering manager for BAT-1. "This is especially important for the manufacture of automotive semiconductors, since burn-in is required to assure the high reliability required in automotive applications."

"We are very pleased with this order from Motorola," stated Aehr Test president and CEO Rhea Posedel. "This follow-on order validates the DiePak carrier as a cost-effective solution for producing Known-Good Die for multichip modules (MCMs) using advanced memory, logic, and application-specific devices. The growing use of bare die for portable and hand-held products is generating significantly greater interest in our DiePak carrier."

To meet the growing demand for DiePak carriers, Aehr Test recently announced the formation of a new business unit, Aehr Test Fixtures (ATf). ATf focuses on the design and manufacturing of DiePak carriers, plus the Company's burn-in and test fixtures, to meet the growing needs of the most advanced semiconductor memory and logic device manufacturers.

The application for DiePak carriers at Sandia National Labs will be to burn-in specialized, custom components for use in aerospace programs as part of multichip modules, according to Rick Pendergrass, Managing Director of ATf. The Sandia program will combine the design of custom carriers along with actual burn-in of devices at Aehr Test's facilities. Pendergrass listed other identified applications for the DiePak/KGD solution as dense MCM assemblies used in various portable devices such as PDAs, network-compatible portable telephones, games and cardiac pacemakers, among others. There is also a growing need for such technology in military electronics where size and weight considerations are at priority levels.

About Aehr Test Systems
Headquartered in Mountain View, Calif., Aehr Test Systems is a leading provider of systems for burning-in and testing DRAMs and other integrated circuits and has an installed base of more than 2,000 systems worldwide. Aehr Test has developed and introduced two innovative product families, the MTX system and DiePak carrier. The MTX is a massively parallel test system designed to reduce the cost of memory testing by performing both test and burn-in on thousands of devices simultaneously. The DiePak carrier is a reusable, temporary package that enables integrated circuit manufacturers to perform cost-effective final test and burn-in of bare die.
