Abstract
Ashing rates of encapsulants exposed to an oxygen plasma in a reactor are increased by simultaneously exposing a solid halogen-substituted hydrocarbon polymer to a plasma jet formed within a cavity in a grounded conductive surface of the reactor. Advantageously the solid reactant may be polyvinyl chloride or polytetrafluorethylene in solid form.
