Aehr Test Systems vs Arm Holdings
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.
Arm Holdings (ARM) reported $3.23B revenue in FY2025 (ended Mar), up 23% YoY. Royalty revenue +17%. Market cap ~$160B. 7,500+ employees. Cambridge, UK. CPU architecture in 99% of smartphones, expanding into AI/datacenter.
About
Arm Holdings designs the CPU architecture used in virtually every smartphone on Earth — over 280 billion Arm-based chips have shipped since 1990. Unlike Intel or AMD, Arm does not manufacture chips; instead, it licenses its instruction set architecture (ISA) and processor designs to companies like Apple, Qualcomm, Samsung, and MediaTek.
