Abstract

A plasma generator for the fabrication of integrated circuit devices is described. The generator includes a separate plasma igniter electrode to apply the electrical power to a gas within a treatment chamber necessary to create a desired plasma. The plasma, once it is initiated, then is sustained by inductive coupling.
