Abstract:
A processing system for processing a substrate with a plasma, the system comprising:a processing chamber defining a processing space and including a substrate support therein for supporting a substrate in the processing space;a gas inlet for introducing a process gas into said processing space;a plasma source operable for creating a plasma in the processing space from process gas introduced therein, the plasma source comprising:a dielectric window having a generally planar surface, the dielectric window interfacing with the processing chamber proximate the processing space;an inductive element positioned outside of the chamber and proximate the dielectric window, the inductive element operable for coupling electrical energy through the dielectric window and into the processing space to create a plasma therein;the inductive element comprising a coil having multiple coil turns disposed successively along the length of the coil, at least one of said coil turns being oriented in a first plane, at least one of said coil turns being oriented in a second plane which is angled from the first plane.
