Abstract:
1. A plasma processing apparatus in which an object to be subjected to plasma processing is loaded for subjecting the loaded object to plasma processing, comprising: a chamber in which plasma processing is performed; a parallel plate type cathode electrode and anode electrode disposed horizontally in said chamber such that respective discharge surfaces thereof are opposed to one another; a holding assembly holding the object on said cathode electrode or said anode electrode; an introduction port for supplying a gas for processing into a plasma generation space between said cathode electrode and said anode electrode where plasma is generated; and a first exhaust port for exhausting gas from within said chamber, said first exhaust port being disposed in an upper wall portion of said chamber above a center of said anode electrode such that said gas supplied through said introduction port and flowing toward a side in said chamber from between said cathode electrode and said anode electrode can be exhausted in an upward direction.
