Abstract:
1. An integrated snubber device on a semiconductor basis for wiring an electric network for absorbing electric energy from an electric energy store of an electric network, comprising: at least two terminals for connecting to the electric network to be wired, an electric resistor structure and a capacitor structure which are connected between the terminals, wherein the capacitor structure comprises a doped semiconductor substrate area forming a first electrode of the capacitor structure, the doped semiconductor substrate area having a dielectric layer arranged thereon which conformingly covers the semiconductor substrate area, and the dielectric layer having a conductive layer arranged thereon which forms a second electrode of the capacitor structure, and wherein an electric resistance of the resistor structure is adjusted via a specific conductivity of the semiconductor substrate area of the first electrode of the capacitor structure.
