Abstract: The disclosure relates to a semiconductor die with a semiconductor device in a semiconductor body, the semiconductor body comprising a silicon carbide substrate; an epitaxial silicon carbide layer system on a first side of the silicon carbide substrate; an interruption layer; wherein the interruption layer is embedded either into the silicon carbide substrate or into the epitaxial silicon carbide layer system, in each case at a vertical distance from the first side of the silicon carbide substrate.

Abstract: Representative implementations of devices and techniques provide an optimized layer for a semiconductor component. In an example, a doped portion of a wafer, forming a substrate layer may be transferred from the wafer to an acceptor, or handle wafer. A component layer may be applied to the substrate layer. The acceptor wafer is detached from the substrate layer. In some examples, further processing may be executed with regard to the substrate and/or component layers.
