PLASMA PROCESSING APPARATUS
First Claim
1. A plasma processing apparatus comprising:
- a processing chamber;
a gas supply unit for supplying a processing gas into the processing chamber;
a microwave generator for generating microwave;
an antenna for introducing the microwave for plasma excitation into the processing chamber;
a coaxial waveguide provided between the microwave generator and the antenna;
a holding unit, disposed to face the antenna in a direction of a central axis line of the coaxial waveguide, for holding a processing target substrate;
a dielectric window, provided between the antenna and the holding unit, for transmitting the microwave from the antenna into the processing chamber; and
a dielectric rod provided in a region between the holding unit and the dielectric window along the central axis line.
