Abstract:
A semiconductor component includes a body with a drift zone, a source zone, a body zone, and a drain zone. A gate forms a MOS structure with the drift zone, with the source zone and with the body zone. An edge termination between the lateral edge and the MOS structure includes a plurality of field rings which enclose the MOS structure. The lateral edge is at the same potential as the drift zone, and the edge termination reduces voltage between the lateral edge and the source zone. A horizontally extending edge plate is disposed at the front side between the lateral edge and the edge termination. The edge plate is at the same potential as the drift zone and forms a plate capacitor structure including a field plate lying above the edge plate.
