About Aehr Test Systems
Aehr Test Systems makes semiconductor test equipment, specifically wafer-level burn-in systems that stress chips before they ship to catch early failures. It earns revenue selling these systems and their consumable WaferPak contactors to chipmakers.
Its product line includes the FOX-XP test platform, WaferPak burn-in contactors, and systems for testing silicon carbide and gallium nitride devices. That SiC and GaN focus ties it to power chips for electric vehicles and AI power infrastructure, and it is now expanding into burn-in for AI processors.
Founded in 1977 and headquartered in Fremont, California, Aehr trades on the NASDAQ and employs about 138 people.
Aehr Test Systems in the AI buildout
Aehr sits in the Semiconductors layer of the buildout on the test and reliability side. Its wafer-level burn-in systems historically served silicon carbide chips for EVs, and the company is now extending the same approach to AI processors, which is its main new growth lever. The base business still follows the EV power semiconductor cycle, so Supercycle scores its AI exposure at 35 out of 100.
AEHR is tracked in Semiconductors, rated Growing on the AI Exposure leaderboard.
