Abstract:
1. A plasma processing apparatus for performing plasma processing with respect to a sample to be processed in a reaction vessel, comprising: microwave generating means that generates microwaves; a first dielectric that is connected to the microwave generating means, the first dielectric having a rectangular section that extends along the surface of the sample to be processed, and which makes an electric field strength distribution of the microwaves generated from the microwave generating means substantially uniform along the surface to be processed of the sample; a slot plate that is provided between the reaction vessel and the first dielectric and having a plurality of first slots formed therein, the slot plate maintaining or further enhancing the uniformity of the electric field strength distribution of the microwaves in the first dielectric; a second dielectric that is provided between the slot plate and the reaction vessel and which maintains or further enhances the uniformity of the electric field strength distribution of the microwaves supplied from the slot plate; and processing means that processes the sample using plasma generated in the reaction vessel by the microwaves.
