Aehr Test Systems (AEHR)

History and Background

Aehr Test Systems was founded in 1977. It has evolved from providing burn-in and test solutions for memory devices to focusing on wafer-level test and burn-in for semiconductors, particularly silicon carbide (SiC) power devices, electric vehicles, and silicon photonics.

Core Business Areas

• Wafer Level Test Systems: Provides systems for testing entire wafers of semiconductors before they are singulated into individual chips. This enables cost-effective testing and burn-in of devices.
• Die Level Test Systems: Provides systems for testing singulated devices, this is a smaller part of their revenue.
• Test Fixtures and Consumables: Provides custom test fixtures, contactors, and other consumables required for their test systems.
• Services and Support: Offers maintenance, training, and engineering services to support their installed base of systems.

Leadership and Structure

Gayn Erickson is the CEO. The company has a typical corporate structure with departments for engineering, sales, marketing, operations, and finance. Public company board and committees.

Key Offerings

• WaferPaku2122 Contactors: Custom designed probe cards that allow for contacting and testing all the die on a wafer at once. The market is highly specialized based on individual device design and manufacturing processes. Competitors include FormFactor (FORM), Technoprobe S.p.A. (TPRO), and SV TCL.
• FOXu2122 Systems: Aehr's flagship product line of automated test and burn-in systems, capable of testing entire wafers simultaneously. Market share is estimated at 25-35% of the wafer-level burn-in segment for silicon carbide and silicon photonics. Competitors include Teradyne (TER), Advantest (ATE), and other custom solution providers.

Industry Overview

The semiconductor test equipment industry is experiencing growth due to increasing complexity of devices, demand for higher quality and reliability, and the growth of automotive, 5G, data center and AI markets that require rigorous testing. Testing SiC power devices used in electric vehicles (EVs) is a major driver.

Positioning

Aehr Test Systems is a niche player focused on wafer-level test and burn-in, particularly for SiC and Si photonics. This specialization allows them to offer solutions tailored to these markets, giving them a competitive edge over larger, more general-purpose test equipment vendors.

Total Addressable Market (TAM)

The estimated TAM for wafer-level burn-in is expanding rapidly with the growth in SiC and silicon photonics. Estimates vary, but projections suggest a multi-billion dollar market in the next 5-7 years. Aehr's positioning allows them to capture a significant portion of this TAM as adoption grows.

Key Competitors

• TER
• ATE
• FORM

Competitive Landscape

Aehr benefits from specializing in wafer-level burn-in and test, but faces strong competition from larger, well-funded companies like Teradyne and Advantest.

Historical Growth: Aehr Test Systems has experienced accelerated growth in recent years due to the adoption of SiC in electric vehicles and other applications. Revenue has grown rapidly.

Future Projections: Analyst estimates project continued growth in revenue and earnings, driven by the SiC market and Aehr's unique technology. Revenue growth is projected to be above the industry average.

Recent Initiatives: Aehr has been focusing on expanding its product line to address new applications and increasing its manufacturing capacity to meet growing demand.

Aehr Test Systems is a niche player in the semiconductor test equipment market, focused on high-growth areas like SiC and silicon photonics. Its specialized technology and strong customer relationships are advantages. However, its small size and reliance on a few key customers create vulnerabilities. The company should focus on expanding its customer base and investing in R&D to maintain its technological edge.
