Abstract
A wafer support, comprising, a baseplate with an aperture therein and a hing ring rotatably positioned in the aperture. A platform is defined in the holding ring for supporting the peripheral edges of a wafer disposed therein and the holding ring includes a plurality of spaced slots extending parallel to the platform and spaced therefrom. A plurality of retaining rods are connected to the baseplate and extend into the slots to engage over the wafer positioned on the platform. A portion of the holding ring adjacent each slot defines a retaining rod abutment for urging each retaining rod out of its respective slot when the holding rod is rotated in the baseplate to release the supported wafer.
