Abstract:
1. A semiconductor wafer handling device, comprising: a first process tank having a fluid supply line for supplying fluid to the tank; a lift control apparatus; a lifting member positionable within the process tank using the lift control apparatus, the lifting member comprising a horizontal wafer engaging portion for engaging a semiconductor wafer and a vertical lifting portion for engaging the lift control apparatus, the vertical lifting portion having a front surface and a back surface, the horizontal wafer engaging portion and the vertical lifting portion oriented such that a side surface of a semiconductor wafer engaged by the horizontal wafer engaging portion is positioned adjacent to, and parallel with, the front surface of the vertical lifting portion, wherein at least one fluid-flow bore is disposed within the vertical lifting portion in communication with said front and back surfaces; wherein when the lifting member is positioned within the tank and fluid is supplied to the tank via the fluid supply line, the fluid is movable through the fluid-flow bore to contact the side surface of the semiconductor wafer; and wherein the fluid-flow bore has a bore axis oriented substantially non-perpendicular to at least one of the front and back surfaces of the lifting member.
