Claim:
1. Transport and handing-over arrangement for disc-shaped substrates, comprising: a carrier with a carrier surface; a tray-shaped substrate carrier held on the carrier surface due to its weight, wherein the substrate carrier includes at least one planar recess accommodation for a substrate, a peripheral protruding rim surrounding the at least one planar recess accommodation such that the substrate lies in the planar recess accommodation below the peripheral protruding rim, and at least one part of magnetisable material; a take-over arrangement with a take-over surface opposite and spaced from the carrier surface, at least one permanent magnet at the take-over arrangement; wherein the substrate carrier and the take-over arrangement are controllably movable relative and parallel to each other, and thereby the at least one part of magnetisable material of the substrate carrier is configured to align with the at least one permanent magnet at the take-over surface and create a magnetic force perpendicular to the substrate carrier during take-over of the substrate carrier by the take-over arrangement, thereby avoiding lateral shifting; wherein further: the distance between the at least one permanent magnet and the at least one part of magnetisable material is controllably variable into first and second predefined distance positions, such that in the first distance position the magnetic force acting on the substrate carrier is larger than the weight of the substrate carrier, and in the second distance position, the magnetic force acting on the substrate carrier is smaller than the weight of the substrate carrier, and wherein the peripheral protruding rim prevents exposure of the substrate to the take-over surface of the take-over arrangement.
