Abstract
A semiconductor component includes a semiconductor body, in which are formed: a substrate of a first conduction type, a buried semiconductor layer of a second conduction type arranged on the substrate, and a functional unit semiconductor layer of a third conduction type arranged on the buried semiconductor layer, in which at least two semiconductor functional units arranged laterally alongside one another are provided. The buried semiconductor layer is part of at least one semiconductor functional unit, the semiconductor functional units being electrically insulated from one another by an isolation structure which permeates the functional unit semiconductor layer, the buried semiconductor layer, and the substrate. The isolation structure includes at least one trench and an electrically conductive contact to the substrate, the contact to the substrate being electrically insulated from the functional unit semiconductor layer and the buried layer by the at least one trench.
