description Apparatus for supporting a workpiece and method of making same. The apparatus comprises a flex circuit laminated to a contoured support pedestal. The flex circuit includes a reinforced layer to improve puncture resistance of the flex circuit. The top surface of the chuck has a contoured topography that is achieved by machining the upper surface of the pedestal prior to lamination of the flex circuit to the pedestal. The contoured topography improves the flow of backside cooling gas resulting in a more uniform wafer temperature profile.
