摘要 |
A plasma processing system is described for generating plasma with a ballistic electron beam using a surface wave plasma (SWP) source, such as a radial line slot antenna (RLSA) during semiconductor device fabrication. The antenna comprises a resonator plate having a partially open, electrically conductive layer coupled to a surface of the resonator plate. For example, the electrically conductive layer is formed at an interface between the resonator plate and the plasma, and a direct current (DC) voltage is applied to the electrically conductive layer.
