Abstract: Wafer cassettes and methods of use that provide heating a cooling to a plurality of wafers to decrease time between wafer switching in a processing chamber. Wafers are supported on a wafer lift which can move all wafers together or on independent lift pins which can move individual wafers for heating and cooling.
