Abstract
Internal components of plasma reactors are composed of a toleratable, ceramic filled plasma-useful polymer such as a high temperature engineering thermoplastic, preferably a polyamideimide or polybenzimidazole. The parts exhibit a low erosion rate upon exposure to plasma at low pressure.
Claims2
A plasma treating apparatus having a vacuum chamber adapted to receive a substrate to be plasma treated, and at least one apparatus component which is exposed to plasma in an interior of the apparatus, wherein the apparatus component is constructed of a plasma-useful polymer filled with from 5 to 40 weight percent of toleratable ceramic particles based on the total weight of plasma-useful polymer and toleratable ceramic, wherein the plasma-useful polymer comprises a recured polyamideimide polymer, and wherein the toleratable ceramic filler comprises boron nitride.
