Abstract
The invention relates to a gripper for handling frames () that are covered with a film () that is intended for the transport of wafers (). The gripper comprises at least two flat fingers () that carry flattened finger tips (). This construction allows to insert the gripper between two frames () that are mounted in a cassette () without complication. The fingers () support in subsections both the frame () and the film (). The film is attached to the frame due to the suction effect exerted by vacuum openings () configured on the frame, thereby fixating the film on the gripper.
