Abstract
A semiconductor substrate carrier for use during wet chemical processing may comprise a conductive flange to couple the carrier with processing equipment, a frame coupled with the conductive flange, where the frame is configured to hold a semiconductor substrate, and an integrated shield coupled with the frame. The integrated shield is configured to alter an electric field near at least a portion of a surface of the semiconductor substrate during the wet chemical processing.
