ASYS

Amtech Systems, Inc.

A maker of equipment that semiconductor factories use to build and package chips — including reflow ovens for advanced packaging (used in AI accelerators), diffusion furnaces, and CMP consumables and wafer-cleaning systems sold under the PR Hoffman, Entrepix, and Intersurface Dynamics brands. The company was incorporated in Arizona in 1981 as Quartz Engineering & Materials, renamed itself Amtech in 1987, and later grew through acquisitions such as BTU International. Its name is a portmanteau of "American" (or "Advanced") and "technology."
