Abstract
A vacuum processing system has a wafer cooling system disposed on a lid of a transfer chamber so that heated wafers are cooled inside the transfer chamber. The wafer cooling system has a wafer lift assembly and a wafer cooler. The wafer cooler has a cooling plate and a coolant tank disposed through the transfer chamber lid. The wafer lift assembly has a lift actuator disposed on the top of the transfer chamber lid, guide rods to translate the lifting motion through the lid, and wafer supports inside the lid to raise the wafer to a position proximate to the cooling plate. The wafer cools by radiating heat up to the cooling plate, and the coolant tank transfers the heat from the cooling plate.
