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."

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: +360.6K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
