Abstract
Placing a conductive member between a plasma chamber in a remote plasma reactor and a substrate to shield the substrate from irradiation of undesirable electromagnetic radiation, ions or electrons. The conductive member blocks the electromagnetic radiation, neutralizes ions and absorbs the electrons. Radicals generated in the plasma chambers flows to the substrate despite the placement of the conductive member. In this way, the substrate is exposed to the radicals whereas damages to the substrate due to electromagnetic radiations, ions or electrons are reduced or removed.
