The invention provides a stage apparatus comprising an object support, a plurality of support members, a gripper and a control unit. The object support comprises a surface for mounting an object on, the surface extending in a plane. The plurality of support members are for supporting the object, and are arranged to receive the object from a gripper and to arrange the object on the surface and/or vice versa.
