Abstract:
A apparatus includes a susceptor and a non-reactive gas source. The susceptor has through holes and a wafer support surface. Each through hole includes a lift pin and a lift pin head. The lift pin has a vertical degree of motion in the through hole to lift up or place a wafer on the susceptor. The lift pin head has at least one flow channel structure running from its first surface at least partially exposed to a bottom side of the susceptor through its second surface exposed to a top side of the susceptor wherein the lift pin. The non-reactive gas source is configured to flow a gas to a backside of the wafer through the flow channel structure through the bottom side of the susceptor.

Claim (Index 11):
An apparatus, comprising:\n a holder having a plurality of through holes and a wafer support surface, wherein each of the through holes is a step through hole, and each of the plurality of through holes includes:\n a lift pin having a vertical degree of motion; and \n a lift pin head on the lift pin, the lift pin head having an outer bottom surface, a top surface, an outer sidewall connected between the outer bottom surface and the top surface, and at least one flow channel structure, one of the at least one flow channel structure is disposed near or on the outer sidewall and runs from the outer bottom surface that is at least partially exposed to a bottom side of the holder via the through hole of the holder through the top surface or the outer sidewall that is exposed to a top side of the holder, wherein the lift pin is operable to lift up or place a wafer on the holder via the lift pin head contacting the wafer, an outer diameter of the lift pin head is greater than an outer diameter of the lift pin, and the one of the at least one flow channel structure includes a groove extending from the outer bottom surface of the lift pin head through a surface of the outer sidewall of the lift pin head to the top surface of the lift pin head; and \n a non-reactive gas source configured to flow a gas to the bottom side of the holder.
