Title:
SURFACE WAVE EXCITATION PLASMA PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2006/120904
Kind Code:
A1
Abstract:
[PROBLEMS] To sustain uniform generation of plasma constantly over a large area. [MEANS FOR SOLVING PROBLEMS] A plasma source (10) comprises a microwave generator, a microwave waveguide (12) and a dielectric block (13), and a plasma source (20) also comprises a microwave generator, a microwave waveguide (22) and a dielectric block (23) similarly. The lid (3) of a chamber (1) is fixed with the microwave waveguides (12, 22) in parallel, and the dielectric blocks (13, 23) are arranged in the chamber (1). A reflector (30) is interposed between the dielectric blocks (13, 23) so that electromagnetic waves (microwaves) propagating through the dielectric blocks (13, 23) are prevented from advancing into counterpart dielectric blocks as reflection waves. Consequently, the plasma sources (10, 20) are controlled independently. Furthermore, a side reflector (40) is arranged at the outer circumference of each of dielectric blocks (23, 13) so that a standing wave of the electromagnetic wave propagating through the dielectric blocks (13, 23) is formed thus forming a large-area standing wave mode of surface wave SW uniformly.
