Abstract: A production method for chips, in which as many method steps as possible are carried out in the wafer composite, that is, in parallel for a plurality of chips disposed on a wafer. This is a method for producing a plurality of chips whose functionality is implemented on the basis of the surface layer of a substrate. In this method, the surface layer is patterned and at least one cavity is produced below the surface layer, so that the individual chip regions are connected to each other and/or to the rest of the substrate by suspension webs only, and/or so that the individual chip regions are connected to the substrate layer below the cavity via supporting elements in the region of the cavity. The suspension webs and/or supporting elements are cut when the chips are separated. The patterned and undercut surface layer of the substrate is embedded in a plastic mass before the chips are separated.
