Asher: March Instruments PX-250 Plasma Asher
Overview
The March Instruments PX-250 Plasma Asher is used to treat samples with an oxygen plasma for various purposes, such as “descumming” (removing invisible layers of organic residue), etching away visible organic films, and for chemically modifying the surface of materials such as PDMS and glass to allow for better adhesion, or to change the surface’s hydrophobic/hydrophilic properties. It can also be used for general cleaning, such as to clean invisible hydrocarbon films that may have condensed onto a brand-new wafer out of the box prior to further processing.
It is a pretty simple machine to learn to use, with fully automatic operation once you go through a simple programming procedure.
