Amtech Systems Inc (NASDAQ: ASYS) is a semiconductor equipment and consumables company that designs, manufactures, and services thermal processing equipment and semiconductor fabrication solutions. It makes money through two reportable segments: Thermal Processing Solutions, which generated $58.1M in revenue for FY2025, and Semiconductor Fabrication Solutions, which generated $21.3M, for total net revenue of $79.4M in FY2025, down 22% from $101.2M in FY2024. The Thermal Processing Solutions segment serves chip packaging, electronic assembly, and power semiconductor markets, while the Semiconductor Fabrication Solutions segment sells consumables, equipment, and services for wafer polishing, cleaning, slicing, and dicing. The company is incorporated in Arizona and headquartered in Tempe, Arizona, with manufacturing and office operations in the United Kingdom, China, Malaysia, and multiple U.S. states. Customer concentration is material: as of September 30, 2025, two Thermal Processing Solutions customers represented 15% and 13% of accounts receivable.

Revenue model

Transactional revenue from equipment sales, replacement parts, consumables, and services across two segments. Thermal Processing Solutions sells reflow equipment, diffusion furnaces, and ceramic-based power semiconductor packaging furnaces. Semiconductor Fabrication Solutions sells wafer polishing consumables, CMP replacement parts, substrate process chemicals, and related services.

Products and services

Thermal Processing Solutions: reflow equipment for chip packaging and electronic assembly, diffusion furnaces, furnaces for ceramic-based power semiconductor packages and passive electronic components. Semiconductor Fabrication Solutions: substrate carriers (3 to 38 inches, multiple materials), lapping and polishing consumables, wafer carriers, CMP replacement parts and assemblies (via Entrepix), substrate process chemicals (via Intersurface Dynamics), and cleaning and dicing equipment and services.

Customers and end markets

End markets include power semiconductors, electric vehicles, industrial electronics, computers, smartphones, wireless communication, and semiconductor wafer manufacturers. Customers include outsourced semiconductor assembly and test (OSAT) providers, wafer fabricators, and electronics manufacturers. As of September 30, 2025, two customers in the Thermal Processing Solutions segment represented 15% and 13% of accounts receivable, indicating material customer concentration.

Value-chain role

Equipment and consumables supplier to the semiconductor manufacturing supply chain. Sits upstream of chip fabrication, providing both capital equipment (furnaces, polishing systems) and recurring consumables (carriers, chemicals, CMP parts) to wafer manufacturers and semiconductor packagers.

Geographic exposure

Manufacturing and operations in Tempe, Arizona (corporate headquarters); Ashvale, Surrey, United Kingdom; Shanghai, China; Penang, Malaysia; Westford, Massachusetts; Phoenix, Arizona; Bethel, Connecticut; Carlisle, Pennsylvania; Spartanburg, South Carolina. Equipment manufacturing for the Thermal Processing segment is conducted in China and through contract manufacturing partners in Canada and Singapore. Polishing consumables manufacturing is in Pennsylvania.
