Abstract: To sustain uniform generation of plasma constantly over a large area. In the surface wave excitation plasma processing device, a plasma source includes: a microwave generator, a microwave waveguide and a dielectric block; and a plasma source also includes: a microwave generator, a microwave waveguide and a dielectric block. The lid of a chamber is fixed onto the microwave waveguides in parallel, and the dielectric blocks disposed in the chamber.

Consequently, the plasma sources are controlled independently. Furthermore, a side reflector is disposed at outer circumference of each of the dielectric blocks so that a standing waves of the electromagnetic waves propagating through the dielectric blocks is formed thus forming a large area standing wave mode of surface waves uniformly.
