Claim 16:
17. A method of processing a substrate, comprising:
positioning a substrate supported on a blade over a pedestal plate of a pedestal disposed within a processing chamber, the pedestal plate having substantially parallel flat edges disposed between adjacent cut outs of a plurality of cut outs disposed along a perimeter of the pedestal plate, wherein each cut out of the plurality of cut outs is between about 90 degrees and about 125 degrees along the perimeter away from each adjacent cut out of the plurality of cut outs on the perimeter of the pedestal plate, wherein the pedestal plate has recesses disposed in a bottom surface of the pedestal plate;
lifting the substrate from tabs positioned on the blade;
transferring the substrate from the blade to a top surface of the pedestal plate, wherein the tabs are lowered beneath the top surface of the pedestal plate upon transferring the substrate, and wherein blade has substantially parallel forks having a uniform thickness, the uniform thickness extending from the tabs to a base of the blade; and
retracting the blade from the pedestal by passing tabs extending from the blade beneath the recesses.
