A method and apparatus for a processing pad assembly for polishing a substrate is disclosed. The processing pad assembly has a conductive processing pad having a plurality of raised features made of a conductive composite disposed on a conductive carrier. The raised features are adapted to polish the feature surface of a substrate and define channels therebetween. The conductive processing pad may have lower features made of a conductive composite that extend into the sub-pad from the conductive carrier. The conductive processing pad is adhered to a sub-pad bound to an opposing conductive layer and the opposing conductive layer bound to a platen assembly.
