Abstract
A semiconductor component has a semiconductor body zone, a first electrically conductive layer adjacent to the semiconductor body zone, a first dielectric layer with first dielectric properties and a second dielectric layer with second dielectric properties. The first dielectric properties differ from the second dielectric properties. The first dielectric layer and the second dielectric layer are arranged between the semiconductor body zone and the first electrically conductive layer. A second electrically conductive layer is applied between the first dielectric layer and the second dielectric layer. A first voltage divider is switched between the first electrically conductive layer and the semiconductor body zone. The second electrically conductive layer is electrically conductively connected only to the voltage divider.
