Abstract: In a system and method to reduce wafer breakages in a wafer handling system, the position of a wafer on a platen is monitored and closing of the platen on a vacuum chamber is prevented if a misaligned wafer is detected. In one embodiment the wafer position is monitored by monitoring the air pressure in vacuum channels of a platen faceplate.
