Abstract
A wafer handling device includes multiple quartets of retention fingers, each having a resting flexure at a distal end that is vertically and torsionally compliant, a housing to which the retention fingers are mounted, a first pair of the retention fingers from a first quartet, the first pair configured to rotate to a first angular position to receive a wafer by the resting flexures, a second pair of the retention fingers from the first quartet configured to rotate to the first angular position after the first pair receives the wafer, and configured to vertically move towards the wafer in the first angular position, where the device grips the wafer at a second side by the second pair and at a first side by the first pair, and a bearing to which the housing is mounted for turning the housing to overturn the wafer 180 degrees.
