Abstract:
1. A method for production of a semiconductor wafer, wherein the method comprises the following method steps: production of a semiconductor wafer with a plurality of semiconductor chip positions arranged in rows and columns, wherein the rear face of the semiconductor wafer comprises a dopant concentration in areas close to the rear face for corresponding flat resistive junctions; deposition of a conductive self-supporting substrate layer on the rear face of the semiconductor wafer, wherein the substrate layer comprises a ternary carbide and/or a ternary nitride and/or carbon; thinning of the semiconductor wafer from the upper face of the semiconductor wafer, and polishing of its upper face; introduction of circuit structures into the semiconductor chip positions in areas close to a surface of the upper face of the semiconductor wafer; application of wiring structures and isolation structures to the upper face of the semiconductor wafer at the semiconductor chip positions; application of a passivation layer to the wiring structures and isolation structures, leaving metallic contact pads free.
