Abstract: A plasma producing apparatus for plasma processing a substrate Includes a chamber having an interior surface, a plasma production device for producing an inductively coupled plasma within the chamber, a substrate support for supporting the substrate during plasma processing, and a Faraday shield disposed within the chamber for shielding at least part of the interior surface from material removed from the substrate by the plasma processing. The plasma production device includes an antenna and a RF power supply for supplying RF power to the antenna with a polarity which is alternated at a frequency of less than or equal to 1000 Hz.
