Abstract:
1. A plasma processing apparatus comprising: a sample stand, which is disposed in an inside of a vacuum container, on which a sample to be processed is placed; an inner wall member which is disposed inside of an outer side wall member of the vacuum container arranged through a space with the outer side wall member, and surrounds a side of the sample stand through space, wherein the inner wall member has an approximately cylindrical shape and faces to a plasma generated in a chamber inside of the inner wall member; a flange portion of the inner wall member, which is formed at an upper periphery portion of the inner wall member and is extended toward an outer direction outside of the chamber; an exhaust device which exhausts and reduces pressure inside the vacuum container; an upper member arranged in the vacuum container above the flange portion of the inner wall member, contacting with an upper surface of the flange portion and transmitting a force pressing downwardly in the state where the inside of the vacuum container is reduced in pressure; and a lower member arranged in the vacuum container, contacted with an outer peripheral portion of the inner wall member at a lower end of the inner wall member and extended toward an outer direction outside of the chamber, wherein the inner wall member is thermally connected with a temperature adjusting device which controls temperature of the inner wall member through the upper surface of the flange portion and the upper member which are brought into contact with each other.
