Abstract:
1. A carrier wafer for mounting a disc-shaped semiconductor component, having a front side and a rear side situated opposite the front side, the carrier wafer comprising a first carrier layer, a first electrically insulating cover layer, a second electrically insulating cover layer which surrounds the first carrier layer, a third electrically conductive layer which is disposed on the second electrically insulating cover layer and includes at least two regions which are separated from each other electrically, each of the regions having an electrode on the front side of the carrier wafer and an electrical contact on the rear side of the carrier wafer, the electrical contact connected to the electrode in an electrically conductive manner, the first electrically insulating cover layer disposed on the third electrically conductive layer and covering at least the front side and an edge of the carrier wafer between the front side and the rear side, at least one of the at least two regions of the third electrically conductive layer having a conductor section which extends from the front side of the carrier wafer around an outer edge of the first carrier layer to the rear side of the carrier wafer and connects the electrode and the electrical contact of the at least one of the at least two regions in an electrically conductive manner.
