Semiconductor component and method for manufacturing semiconductor component

Abstract

The present invention relates to a semiconductor component and a method for manufacturing the same. The semiconductor component comprises a semiconductor body, which includes a substrate of a first conducting type, a buried semiconductor layer of a second conducting type being arranged on the substrate, a functional cell semiconductor layer of a third conducting type being arranged on the buried semiconductor layer. The functional cell semiconductor layer provides at least two semiconductor functional cells being arranged landscape orientation in a row. The buried semiconductor layer is part of at least one semiconductor functional cell. The semiconductor functional cells are electrically insulated with each other by means of the functional semiconductor layer, the buried semiconductor layer and the separating structure of the substrate. The separating structure comprises at least a trench and a conducting contact with the substrate, the contact is electrically insulated with the functional cell semiconductor layer and the buried layer by means of at least one trench.
