A method and system for material processing employing extracting equivalent fluxes of positive and negative ions at two surfaces from an ion-ion plasma without substantially altering the plasma potential. The extraction is achieved by applying a continuously applied bias to the substrate being processed, in order to attract the ions to the substrate surface to facilitate materials processing such as etching, deposition and chemical modification at the surface. The continuously applied bias is applied via a power source coupled to the plate, also referred to as a stage or chuck, holding the substrate.
