Abstract:
1. A plasma processing apparatus characterized by comprising: a process chamber; base material holding means for arranging a base material at a predetermined position in said process chamber; and a plasma source to selectively irradiate a base material with at least one of a plasma, charged particle, and radical, wherein said plasma source includes at least a chamber to which a gas should be supplied; and a hollow cathode electrode member which is arranged on a gas flow-out side of said chamber and has a plurality of electrode holes through which the gas can flow, and said hollow cathode electrode member comprises a plurality of stacked porous hollow cathode electrode members, to which voltage is applied independently and individually, and which are combined through dielectric porous spacers, and microcathode plasma discharge is performed in the electrode holes of said hollow cathode electrode member.
