Aehr Test Systems, Inc. AEHR

Company Overview

Aehr Test Systems, Inc. is a provider of semiconductor test and reliability qualification equipment, operating within the semiconductor capital equipment and electronic test systems industries. The company designs and manufactures solutions used to validate the performance, durability, and reliability of integrated circuits, with a particular emphasis on devices used in high-growth end markets such as electric vehicles, renewable energy, and advanced industrial applications.

The company’s primary revenue drivers are systems and consumables used for burn-in, stress testing, and production test of semiconductor devices, especially silicon carbide (SiC) power semiconductors. Aehr is recognized for its proprietary wafer-level testing approach, which enables parallel testing of entire semiconductor wafers rather than individual packaged devices, offering potential cost, throughput, and quality advantages. Founded in 1977, the company has evolved from traditional packaged-device burn-in systems to advanced wafer-level solutions aligned with next-generation power and logic semiconductor manufacturing.
