March Asher

The March PX250, is a highly versatile plasma etcher. It will produce three distinctly different plasma conditions: 1) Standard plasma etch, 2) Reactive Ion Etch, and 3) Downstream Plasma Etch. It achieves this via a system of removable and reversible electrode shelves whereby the substrates to be etched can be placed on a grounded or powered or neutral shelf, thus producing the various plasma etch conditions. We have initially assigned this tool for oxygen plasma ashing of organic films mainly photoresist.
