Embodiments disclosed herein include a plasma source, an abatement system and a vacuum processing system for abating compounds produced in semiconductor processes. In one embodiment, a plasma source includes a dielectric tube and a coil antenna surrounding the tube. The coil antenna includes a plurality of turns, and at least one turn is shorted. Selectively shorting one or more turns of the coil antenna helps reduce the inductance of the coil antenna, allowing higher power to be supplied to the coil antenna that covers more processing volume. Higher power supplied to the coil antenna and larger processing volume lead to an improved DRE.

Method and apparatus for gas abatement

Apparatus for treating a gas in a conduit of a substrate processing system are provided. In some embodiments, an apparatus for treating a gas in a conduit of a substrate processing system includes: a dielectric tube configured to be coupled to a conduit of a substrate processing system to allow a flow of gases through the dielectric tube, wherein the dielectric tube has a conical sidewall; and a radio frequency (RF) coil wound about an outer surface of the conical sidewall of the dielectric tube. In some embodiments, the RF coil is hollow and includes coolant fittings to couple the hollow RF coil to a coolant supply.
