Aehr Test Systems (AEHR) reported ~$80M revenue in FY2024. Provides wafer-level burn-in and test systems for silicon carbide semiconductors used in EV powertrains and solar inverters. HQ: Fremont, CA.
Aehr Test Systems is a semiconductor test equipment company specializing in wafer-level burn-in and test systems, with a dominant position in testing silicon carbide (SiC) power semiconductors. Silicon carbide devices are essential components in electric vehicle inverters, solar inverters, and industrial power systems — they handle high voltages and temperatures where traditional silicon fails. Before shipping, SiC semiconductors must undergo burn-in testing at elevated voltage and temperature to screen out early-life failures, and Aehr's FOX-XP wafer-level system performs this screening more efficiently than component-level testing.
