Aehr Test Systems Announces Achievement of NAND Flash Testing Milestone on FOX-XPTM Multi-Wafer Test and Burn-in System

FREMONT, Calif., May 27, 2015 (GLOBE NEWSWIRE) -- Aehr Test Systems (Nasdaq:AEHR), a worldwide supplier of semiconductor test and burn-in equipment, today announced the achievement of an important milestone in the development of its next-generation FOX-XP Wafer-Level Test and Burn-in System. The achievement of NAND flash testing is one of a series of NRE funding related milestones associated with the customer evaluation order the Company announced in January from a leading IC manufacturer for the FOX-XP multi-wafer solution.

Working with this leading IC manufacturer, Aehr Test successfully demonstrated test and correlation of a high-density NAND flash memory with its next-generation FOX-P system electronics. The test results showed correlation with the IC manufacturer's current production Automated Test Equipment (ATE) test system, including matching the failing bits within the flash memory.

Gayn Erickson, President and CEO of Aehr Test Systems, commented, "We are very excited to announce this important milestone in the development of our next-generation FOX-P systems. We expect our new FOX-XP system to open up significant opportunities for Aehr Test, particularly in the rapidly growing NAND SSD market. We believe that wafer-level burn-in and test is a key enabler for producing reliable multi-die stacked NAND packages for enterprise Solid State Drives (SSDs) and other high-reliability and stacked-die applications in a cost effective way."

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 contactors, which are designed to provide 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 tens of thousands of probes to contact all devices simultaneously on wafers and substrates up to 300mm in diameter. The FOX-XP system is being developed in configurations with 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 annually.
