Aehr Test Systems is one of the leading worldwide providers of systems for burning-in and testing DRAMs, Flash, and other memory and logic integrated circuits. It has an installed base of more than 2,500 systems worldwide and has developed and introduced several products, such as FOX, MTX and MAX systems and the DiePak carrier. The FOX system is a full-wafer contact test and burn-in system. The MTX system is a parallel test system designed to reduce the cost of memory testing by performing both test and burn-in on thousands of devices simultaneously. The MAX system can effectively burn-in and functionally test complex devices, such as digital signal processors, microprocessors, microcontrollers and systems-on-a-chip. Aehr Test Systems DiePak carrier is a reusable, temporary package that enables integrated circuit manufacturers to perform final test and burn-in of bare die. Aehr Test Systems maintains corporate headquarters Fremont, Calif.

Lam Research Corporation, founded in 1980, is one of the leading suppliers of wafer fabrication equipment and services to the world's semiconductor industry. The company provides various types of etch systems, including dielectric etch, conductor etch, resist strip and Synergy cleaning products. Its etch and chemical mechanical planarization products selectively remove portions of various films from the wafer to create semiconductors. The company also develops intellectual property for integrated processing solutions. Its Synergy standalone clean system is used to clean wafers both before and after a range of semiconductor processing steps. Lam Research Corporation is headquartered in Fremont, Calif., and maintains a network of facilities throughout the United States, Japan, Europe, and Asia.

AXT designs, develops, manufactures and distributes high-performance compound semiconductor substrates. The company s customers use its products to fabricate integrated circuits for electronic systems that operate the latest lighting displays and fiber-optic and wireless communications applications.
