Claim 10:
11. A support assembly comprising:
a rotatable center base defining a rotational axis;
at least two support arms extending from the center base orthogonal to the rotational axis, each of the support arms having an inner end in contact with the center base and an outer end;
a heater positioned on the outer end of each of the support arms, each of the heaters having a support surface configured to support a substrate during processing and each of the support surfaces are substantially coplanar, the heaters comprising an electrostatic chuck, each heater having a ring shaped sealing platform positioned around the heater, the sealing platforms having a top surface forming a plane that is substantially parallel with a plane formed by the support surface of the heaters;
a channel formed in the rotatable center base and the support arms, the channel configured to route electrical connections to the plurality of heaters;
a first motor connected to the rotatable center base to rotate the rotatable center base, support arms and heaters around the rotational axis; and
a second motor connected to the rotatable center base to move the rotatable center base, support arms and heaters in a direction along the rotational axis.
