Aehr Test Systems to Exhibit at SEMICON West in San Francisco July 10-12, 2018

FREMONT, Calif., July 02, 2018 (GLOBE NEWSWIRE) -- Aehr Test Systems (NASDAQ:AEHR), a worldwide supplier of semiconductor test and burn-in equipment, today announced that it will be showcasing its FOX-XP next generation multi-wafer test and burn-in systems for high volume production and early failure rate (EFR) test in booth 5381 at SEMICON West 2018, taking place July 10-12 at the Moscone Convention Center in San Francisco, California.

In addition, Aehr Test President and CEO Gayn Erickson will be presenting the keynote address to the attendees at this year’s Test Vision 2020 conference on Wednesday, July 11 at 10am Pacific.  Held in conjunction with SEMICON West, the conference is today's premier workshop for semiconductor and system test experts that includes providers and users of test IP and equipment and is organized with a vision towards the future of test, to discuss upcoming trends, innovations, and requirements.

Mr. Erickson commented, “With the increasing requirements on semiconductors to meet the safety, security, and mission critical reliability needs of the automotive, mobile, and wearable biosensor markets, a key question for the semiconductor industry is what the most effective test strategy is to address these devices. The industry has the challenge to develop and implement test strategies that combine traditional automated functional test, reliability / burn-in, and system level test equipment for a wholistic methodology to capture and weed out manufacturing related defects and infant mortality failures to meet quality and reliability needs that the industry may have never faced in the past.

“Aehr Test is a unique supplier of both complete production solutions as well as individual components including chambers, electronics, and thermal control that can be combined with applications-specific hardware designed with or provided by the customer. Aehr partners with our customers to develop solutions to meet their needs for a range of new applications where new solutions are needed to test and burn-in devices in their application environment. This includes automotive vehicle control and sensor systems, sensors and security devices in mobile smartphones and tablets, and an entire new need for reliability and assurance of operation in wearable biosensors.”

The solutions Aehr Test will feature at its SEMICON West exhibit booth include:

• The FOX-XP system, the company’s next-generation multi-wafer and now singulated die/module test solution that is capable of functional test and burn-in/cycling of flash memories, microcontrollers, sensors, and other leading-edge ICs in wafer form before they are assembled into single or multi-die stacked packages. The FOX wafer-level systems utilize Aehr Test's FOX WaferPak^TM contactors, which provide cost effective solutions for making electrical contact with a full wafer or substrate in a multi-wafer environment. The new configuration with the DiePak^® Carriers also enables burn-in of singulated die and multi-die modules to screen for defects in both the die and the module assembly process. The resulting known-good die or single-die or stacked-die packaged parts can then be used for high reliability and quality applications such as enterprise solid state drives, automotive devices, highly valuable mobile applications, and mission critical integrated circuits and sensors.

• The FOX-1P^TM system, Aehr Test’s second generation of its single-wafer FOX-1 platform originally introduced in 2006, which has proven to be a cost saving high-volume production solution for single touchdown 300mm full-wafer parallel test. The new FOX-1P system can be configured with over 16,000 “Universal Channels” and features a massively parallel test interface, which enables testing over a thousand die in a single touchdown.

• The ABTS^TM family of packaged part burn-in and test systems, which is based on a state-of-the-art hardware and software platform that is designed to address not only today’s devices, but also future devices for many years to come. This system can test and burn-in high pin-count devices and there are also configurations for both high-power and low-power applications.

The key features of the FOX-XP test cell that contribute to the cost-effectiveness of the solution include the ability to provide up to 2,048 “Universal Channels” per wafer or DiePak carrier, which allows the system to test all the devices on the wafer or DiePak carrier in parallel. The innovative “Universal Channel” architecture allows any channel to be any function (I/O, Device Power Supply (DPS) or Per-pin Precision Measurement Unit (PPMU)). This enhanced architecture now allows customers to perform per pin parametric testing, more extensive digital pattern test with deeper data stimulus / capture memory (32M per pin), and deeper scan (768M) optimized for BIST/DFT testing.

A single FOX-XP test system may be configured with up to 18 slots of test resources enabling up to 18 wafers to be tested simultaneously. It also includes Aehr’s proprietary WaferPak full wafer contactor or DiePak carrier, which enables meeting the very high pin count and small pad size and pad pitch requirements of today’s devices, and Aehr’s high performance thermal chucks that enable managing the temperature of the high power density of the devices under test. The footprint of the 18-slot test system is similar to the footprint of typical semiconductor Automatic Test Equipment (ATE) that can only test one wafer at a time.

With the highest wafer throughput available in the ATE industry, the flexibility of Aehr Test’s new “Universal Channel” architecture, and the ability to perform both functional pattern verification and parametric testing at full-wafer parallel test, the FOX-XP system provides a highly differentiated solution from competitive alternatives.

About Aehr Test Systems

Headquartered in Fremont, California, Aehr Test Systems is a worldwide provider of test systems for burning-in and testing logic, optical 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, incremental capacity needs, and new opportunities for Aehr Test products in package, wafer level, and singulated die/module level test. Aehr Test has developed and introduced several innovative products, including the ABTS^TM and FOX-P^TM families of test and burn-in systems and FOX WaferPak^TM Aligner, FOX-XP WaferPak Contactor, FOX DiePak^® Carrier and FOX DiePak Loader. The ABTS system is used in production and qualification testing of packaged parts for both lower power and higher power logic devices as well as all common types of memory devices. The FOX-XP system is a full wafer contact and singulated die/module 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, systems-on-a-chip, and integrated optical devices. The WaferPak contactor contains a unique full wafer probe card capable of testing wafers up to 300mm that enables IC manufacturers to perform test and burn-in of full wafers on Aehr Test FOX systems. The DiePak Carrier is a reusable, temporary package that enables IC manufacturers to perform cost-effective final test and burn-in of both bare die and modules.
