Patent attributes
A device (1) for holding a planar substrate (4), in particular for a wafer or an eWLB, is shown, with a support (2) which forms a supporting surface (3) for the substrate (2) and has at least one recess (5) provided in the region of the supporting surface (3) for the substrate (2), and with at least one holding means which is connected in terms of flow to said recess (6) and is intended for fixing the substrate (2) on the device (1) with the aid of a vacuum generated between the support (2) and substrate (4). In order to be able to grip a multiplicity of substrates of geometrically differing profile, it is proposed that the support (2) has at least one recess (6) with an elastic seal (7) which is designed to be movable from a position (9) protruding over the edge (8) of the recess (6) into a position (10) pulled back in relation to the edge (8) of the recess (6) or at most corresponding to said edge and which interacts with the recess (5) for sucking the full area of the substrate (4) onto the support (2).
