PLASMA PROCESSING APPARATUS

摘要

A plasma processing apparatus of the present disclosure includes a processing container provided with an opening to carry an object to be processed (“workpiece”) into or out of a chamber adjacent to the processing container; a microwave introducing mechanism configured to introduce microwaves into the processing container; an exhaust device configured to evacuate the processing container; and a thermal insulating member provided between an outer surface of a gate valve that is provided near the opening and the chamber adjacent to the processing container. The thermal insulating member is coated with a conductive film at least on a surface of the thermal insulating member facing the outer surface of the gate valve, a surface of the thermal insulating member facing the chamber adjacent to the processing container, and a surface of the thermal insulating member exposed to outer air.
