Abstract:
1. A system comprising: a semiconductor wafer including opposing, major front and back surfaces joined by a circumferential side, the wafer undergoing processing including electroplating a damascene layer on the wafer; and an arrangement configured to apply a polymer coating to the side of the wafer before electroplating the damascene layer, the polymer coating being applied to the side but not at least a portion of the front and back surfaces of the wafer, the polymer coating providing a barrier to formation of the damascene layer on the side of the wafer, wherein the system is configured to apply the polymer coating in accordance with an electrophoresis technique, wherein the arrangement comprises a holder and a bath container filled with polymer fluid, wherein the holder comprises one or more rollers configured to rotate the wafer about an axis generally perpendicular to the front and back surfaces of the wafer, and wherein the one or more rollers are in direct contact with the wafer.
