Abstract | Apparatus for controlling thermal uniformity of a substrate-facing surface of a showerhead are provided herein. In some embodiments, a heat transfer system includes a heat transfer plate having a first diameter and a plurality of independent flow paths disposed within the heat transfer plate, each flow path having a first inlet and a first outlet; a supply conduit system having a second inlet fluidly coupled to a plurality of second outlets, wherein each second outlet is fluidly coupled to a corresponding first inlet of the heat transfer plate; and a return conduit system having a third outlet fluidly coupled to a plurality of third inlets, wherein each third inlet is fluidly coupled to a corresponding first outlet of the heat transfer plate, wherein the supply conduit system and the return conduit system are each disposed within an imaginary cylindrical projection above the heat transfer plate. |
