    Abstract: A platen for polishing a surface of a wafer has a reaction plate, a polishing plate, and a bladder. The reaction plate has a top and bottom surface, and defines a longitudinal axis. The polishing plate is positioned coaxially with the reaction plate. The polishing plate has a second top surface and a second bottom surface. The second top surface is adjacent to the bottom surface of the reaction plate. The bladder is coaxially located along a radially outer portion of either the top or bottom surface of the reaction plate. The bladder is connected with the polishing plate and able to expand to deform the polishing plate with respect to the bottom surface of the reaction plate.
