Abstract:
1. A substrate support assembly adapted to support a large area substrate inside a process chamber, comprising: a unitary, thermally conductive body comprising a metal or metal alloy, the thermally conductive body having one or more substrate support pin holes and one or more cooling channels within the thermally conductive body, wherein the one or more cooling channels are configured to form one or more inner cooling loops and one or more outer cooling loops, the inner and outer cooling loops being configured to flow cooling fluid in opposite flow directions, and wherein the inner cooling loops and the outer cooling loops are spaced apart from the one or more substrate support pin holes; a substrate support surface on the surface of the thermally conductive body and adapted to support the large area substrate thereon; and one or more heating elements embedded within the thermally conductive body, wherein one of the one or more inner cooling loops and one of the one or more outer cooling loops are disposed parallel to each other and parallel to one of the one or more heating elements.
