Abstract
A workpiece transfer assembly for manipulating one or more workpieces, such as semiconductor wafers includes a plurality of coacting arms that include one or more arcuate portions corresponding to an outer diameter of a workpiece. The arcuate portion has a workpiece engaging surface adapted to engage an outer edge of the workpiece. At least one of the coacting arms includes a flexure assembly that allows deformation of the workpiece engaging surface in a direction away from the workpiece in response to pressure on the outer edge of the workpiece from the workpiece engaging surface.
