    摘要: The invention provides a plurality of plasma tuning rod subsystems. The plasma tuning rod subsystems can comprise one or more microwave cavities configured to couple electromagnetic (EM) energy in a desired EM wave mode to a plasma by generating resonant microwave energy in one or more plasma tuning rods within and/or adjacent to the plasma. One or more microwave cavity assemblies can be coupled to a process chamber, and can comprise one or more tuning spaces/cavities. Each tuning space/cavity can have one or more plasma tuning rods coupled thereto. Some of the plasma tuning rods can be configured to couple the EM energy from one or more of the resonant cavities to the process space within the process chamber and thereby create uniform plasma within the process space.

    摘要: A surface wave plasma (SWP) source couples pulsed microwave (MW) energy into a processing chamber through, for example, a radial line slot antenna, to result in a low mean electron energy (Te). To prevent impingement of the microwave energy onto the surface of a substrate when plasma density is low between pulses, an ICP source, such as a helical inductive source, a planar RF coil, or other inductively coupled source, is provided between the SWP source and the substrate to produce plasma that is opaque to microwave energy. The ICP source can also be pulsed in synchronism with the pulsing of the MW plasma in phase with the ramping up of the MW pulses. The ICP also adds an edge dense distribution of plasma to a generally chamber centric MW plasma to improve plasma uniformity.
