Plasma processing system and surface processing method
First Claim
1. A plasma processing system in which gas is introduced into a plasma processing chamber, and a microwave is supplied to said plasma processing chamber through an annular waveguide having a plurality of slots provided at predetermined intervals in a circumferential direction on the same plane facing a surface to be processed of an object to be processed on the plasma processing chamber side to generate the plasma within said plasma processing chamber, wherein said annular waveguide includes an input side waveguide and an output side waveguide, and said slots are bored to be provided between said waveguides at predetermined intervals in a circumferential direction.

Abstract
To provide a plasma processing system capable of introducing a uniform microwave into a plasma processing chamber irrespective of conditions, and a surface processing method using the same. A plasma processing system in which air in a plasma processing chamber is exhausted by an exhaust unit, a microwave is supplied to the plasma processing chamber through an annular waveguide which is bored to be provided at predetermined intervals in a circumferential direction on the same plane facing a surface to be processed of an object to be processed on the plasma processing chamber side to generate plasma within the plasma processing chamber, wherein the annular waveguide is separated into two layers of an input side waveguide and an output side waveguide, and the slots are bored to be provided between these waveguides at predetermined intervals in a circumferential direction.
