Aehr Test Systems Announces Order For FOX™-XP Multi-Wafer System Evaluation

FREMONT, Calif., Jan. 26, 2015 (GLOBE NEWSWIRE) — Aehr Test Systems (Nasdaq:AEHR), a worldwide supplier of semiconductor test and burn-in equipment, today announced a purchase order from a leading IC manufacturer for a custom FOX Multi-Wafer Test System WaferPakTM Contactor and evaluation activities that will enable the manufacturer to qualify Aehr Test’s next-generation FOX-XP multi-wafer system and FOX WaferPakTM Contactor for production test and burn-in of its devices. The customer evaluation plan includes milestones for providing the WaferPak contactor, developing test plans and supporting correlation studies over the next two quarters.

Gayn Erickson, President and CEO of Aehr Test Systems, commented, “We are very excited to announce this agreement representing our first customer commitment to evaluate the FOX-XP solution. This is an important commitment from this customer that can lead to a significant opportunity for Aehr Test, and we believe that this customer’s application is a great fit for our next-generation multi-wafer test system.”

Aehr Test is developing the FOX-XP system, its next-generation multi-wafer test solution that is capable of functional test and burn-in/cycling of flash memories, microcontrollers and other leading-edge ICs in wafer form before they are assembled into multi-die stacked packages. These stacked packages can then be used for high reliability and quality applications such as enterprise solid state drives, automotive devices, mission critical integrated circuits and sensors. The FOX-XP system utilizes Aehr Test’s FOX WaferPak contactor, which provides a cost effective solution for making electrical contact with a full wafer or substrate in a multi-wafer environment. Aehr Test’s WaferPak contactors contain up to 10s of thousands of probes to contact all devices on wafers and substrates up to 300mm simultaneously. The FOX-XP system is being developed in configurations up to 25 wafers in parallel in a single system to operate within an efficient manufacturing space footprint. Aehr Test estimates the test equipment and consumables for this emerging market will add $200 million to $300 million to its served available market. As previously disclosed, Aehr Test expects first shipments of the FOX-XP system by the latter part of calendar 2015.
