Abstract

A single piece ceramic platen is disclosed. This platen may be manufactured using additive manufacturing. The single piece ceramic platen may be manufactured using additive manufacturing processes. As such, the single piece ceramic platen may include a plurality of embedded features. Electrodes, cooling channels, heating elements, temperature sensors, strain gauges and back side gas channels may each be embedded in the electrode. Incorporation of cooling channels and heating elements allows the platen to operate over a wider range of temperatures. Further, these features may be disposed on a plurality of different depths following a planar or non-planar pathway. For example, the heating elements may be configured such that heating element in one region of the platen, such as an outer edge, are disposed closer to the top surface of the platen.
