Claim:
1. A semiconductor substrate carrier in combination with a first semiconductor substrate and a second semiconductor substrate for continuous processing with low cost leadframe strip plating equipment and without semiconductor fabrication plant (fab) equipment 100-200 wafers per hour, comprising: a conductive flange configured to couple the carrier with the low cost leadframe strip plating equipment to provide a temporary electrical connection between the continuous processing equipment, the first semiconductor substrate, and the second semiconductor substrate, wherein the conductive flange comprises a flexibility to elastically bend in an arc comprising a radius of 60 centimeters during the continuous processing; a non-conductive frame coupled with the conductive flange, the frame comprising a first ring-shaped frame piece and a second ring-shaped frame piece positioned opposite the first ring-shaped frame piece, wherein the frame comprises an inside diameter; the first semiconductor substrate disposed within the frame, wherein the inside diameter of the frame is smaller than a diameter of the first semiconductor substrate and the conductive flange is in electrical contact with an outer 2.5 mm edge of the first semiconductor substrate in a radial direction; the second semiconductor substrate disposed back-to-back with the first semiconductor substrate within the frame, wherein the inside diameter of the frame is smaller than a diameter of the second semiconductor substrate and the conductive flange is in electrical contact with an outer 2.5 mm edge of the second semiconductor substrate in a radial direction; a first integrated shield in direct contact with the first ring-shaped frame piece, the first semiconductor substrate disposed in a fixed position between the first ring-shaped piece and the second ring-shaped piece, wherein the first integrated shield is operative to alter an electric field near a portion of a surface of the first semiconductor substrate during wet chemical processing; and a second integrated shield in direct contact with the second ring-shaped frame piece, the second semiconductor substrate disposed in a fixed position between the first ring-shaped piece and second ring-shaped piece, wherein the second integrated shield is operative to alter an electric field near at least a portion of a surface of the second semiconductor substrate during wet chemical processing.
