Claim Text:
1. A mounting apparatus for mounting and holding one structure side of a substrate, the one structure side having structures thereon and the structures having an upper surface that is displaced from the structure side of the substrate such that a structure gap is formed between the upper surface of the structures and the structure side of the substrate, said mounting apparatus comprised of: a mounting element having a substantially circular mounting surface, the mounting surface having suction channels that are formed through the mounting surface and located on an outer ring surface of the mounting surface, the mounting surface being formed as a planar flat mounting surface for supporting the structures on said one structure side, the suction channels opening at suction holes such that when the substrate is mounted and held by the mounting apparatus the structures are in contact with the mounting surface and the suction holes are located at least partially radially outward from the structures relative to a rotational center of the mounting surface, the suction holes being displaced from the structure side of the substrate such that a ring gap is formed between the structure side of the substrate and the suction holes, and the ring gap being formed such that a continuous fluid flow through the ring gap and the suction channels is maintained while the substrate is being held by the mounting apparatus.
