PLASMA CREATION DEVICE AND PLASMA PROCESSING DEVICE

摘要

There is provided a plasma generation device, comprising: a waveguide configured to propagate a microwave; a plasma generation vessel connected to the waveguide; and a dielectric window interposed between the waveguide and the plasma generation vessel to introduce the microwave propagated by the waveguide into the plasma generation vessel. The plasma generation vessel is sphere-shaped and is disposed adjacent to a processing vessel configured to accommodate a substrate, and an interior of the plasma generation vessel is in communication with an interior of the processing vessel.
