摘要:
A compact plasma generating apparatus providing high efficiency of plasma excitation is presented. A plasma generating apparatus (100) comprises a microwave generating apparatus (10) for generating microwaves, a coaxial waveguide (20) having a coaxial structure comprising an inner tube (20a) and an outer tube (20b), a monopole antenna (21) being attached to one end of said inner tube (20a), for directing the microwaves generated by said microwave generating apparatus (10) to the monopole antenna (21), a resonator (22) composed of dielectric material for holding the monopole antenna (21), and a chamber (23) in which a specific process gas is fed for plasma excitation. The chamber (23) has an open surface and the resonator (22) is placed on this open surface, and the process gas is excited by the microwaves radiated from the monopole antenna (21) through the resonator (22) into the interior of the chamber (23) to generate plasma.
