Beschreibung
Zusammenfassung:	A substrate support having heat transfer enhancing topography. Generally, the substrate support includes a first side that supports the substrate and a second side. A ring and a plurality of substrate support pads project from the first side. The ring is disposed proximate the perimeter of the substrate support. A fluid passage is disposed through the substrate support and is coupled to a well disposed in the first side. A plurality of gas flow channels are disposed in the first side and orientated radially outward from the well to a perimeter channel disposed radially inward and adjacent to the ring.
