1. A plasma processing apparatus comprising:
- a microwave generation source;
a waveguide for supplying the microwaves from the microwave generation source;
a cavity resonator for resonating the microwaves supplied from the waveguide to increase the amplitude thereof;
a slit means having at least one slit provided on a wall of the cavity resonator which can transmit the microwaves; and
a plasma producing chamber in which plasma is produced by the microwaves introduced through the at least one slit and the wall separating the plasma producing chamber from said cavity resonator and by externally introduced processing gas, and a substrate is processed by the plasma.

Abstract
Microwaves supplied from a magnetron through a waveguide are resonated in a cavity resonator to increase their amplitude. The resonated microwaves are emitted into a plasma production chamber through slits and a wall. Then plasma is produced in the plasma production chamber into which plasma processing gas is introduced. The plasma is employed for uniformly processing a substrate.
