Aehr Test Systems vs KLA Corp
Side-by-side comparison of AI visibility scores, market position, and capabilities
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.
About
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.
KLA Corp (KLAC) reported $9.9B revenue in FY2024. World's #1 semiconductor inspection and metrology equipment maker. ~16,000 employees. HQ: Milpitas, CA. Market cap ~$80B.
About
KLA Corporation is the world's leading provider of process control and semiconductor inspection and metrology equipment, headquartered in Milpitas, California. Founded in 1975 as KLA Instruments and merged with Tencor in 1997, KLA develops the equipment that semiconductor manufacturers use to detect defects and measure dimensions at atomic scales during chip fabrication. Without KLA's inspection tools, chipmakers cannot achieve nanometer-scale precision for advanced semiconductors. KLA reported revenues of $9.9B in fiscal year 2024 (ending June 2024).
