Abstract

Embodiments of the present invention are directed to a pallet assembly which facilitates direct cooling of the wafer carrier. In one embodiment, the pallet assembly comprises a frame which holds at least one carrier of a component. The pallet assembly further comprises a tray which is operable for being mechanically coupled with the frame. The tray comprises at least one discreet region which corresponds with the carrier when the tray is coupled with the frame. In embodiments of the present invention, the discreet region comprises at least one hole extending through the tray for permitting a coolant medium to dissipate heat from the carrier.
