Claim Text:
1. A wafer handling mechanism comprising: a spatulate body having a distal end and proximal end, the distance between the distal end and the proximal end being larger than the wafer that is to be handled; and, at least two wafer supports coupled to the spatulate body, a combined maximal height of the spatulate body, wafer, and wafer support being less than a distance between immediately adjacent wafers contained in a cassette of wafers, at least one of the wafer supports having a horizontal support surface at a height sufficiently different from the height of the horizontal support surface of the at least one other wafer support to ensure a non-zero distance between a wafer supported by the wafer supports and the spatulate body; wherein the at least two wafer supports includes a first wafer support and a second wafer support, and further wherein the first wafer support defines a maximum horizontal support surface distance of the first wafer support relative to the spatulate body, and further wherein the second wafer support defines a maximum horizontal support surface distance of the second wafer support relative to the spatulate body, and even further wherein the maximum horizontal support surface distance of the first wafer support is greater than the maximum horizontal support surface distance of the second wafer support.
