Patent ID: 11611003

Abstract:
A semiconductor component, in particular for a varactor, having at least one first semiconductor layer and a second semiconductor layer. At least two identical surface electrodes are arranged directly or indirectly on the second semiconductor layer facing away from the first semiconductor layer in order to form two anti-serially connected diodes. The surface electrodes are arranged in an interacting manner such that a load carrier zone which forms the common counter electrode for the surface electrodes is arranged in the first semiconductor layer at least in the operating state, and at least one control contact for controlling the potential of the load carrier zone is provided in a region of the load carrier zone on the second semiconductor layer face facing away from the first semiconductor layer. The load carrier zone produces a continuous electric connection from the counter electrode to the at least one control contact at least in the operating state, and the load carrier zone protrudes beyond the surface electrodes in a projection onto the rear face of the semiconductor component.
