Zusammenfassung:	In an example, a showerhead pedestal assembly for a substrate processing chamber is provided. The showerhead pedestal assembly includes a faceplate. A platen is disposed within the faceplate and includes a heater element extending through at least one groove in the faceplate. The at least one groove is profiled to accept at least one portion of the heater element. A periphery of the platen is joined to an interior surface of the faceplate by a friction stir welded joint.
