摘要: A wafer gripper assembly comprises first and second gripping members movably supported relative to each other. A motor propels the gripping members linearly towards and away from each other. Preferably both gripping members are movably supported, and a rotary-to-linear translator produces equal and opposite linear movement of the gripping members. Typically, at least six contactor elements are defined on the pair of gripping members. The contactor elements include a vertically extending portion having an inwardly facing convex surface for contacting an edge of a wafer, and an inwardly extending flange for supporting a lower surface of the wafer.
