Abstract:
A semiconductor device includes a drift region of a first doping type, a junction between the drift region and a device region, a compensation region of a second doping type, and at least one field electrode structure arranged between the drift region and the compensation region. The at least one field electrode includes a field electrode and a field electrode dielectric adjoining the field electrode. The field electrode dielectric is arranged between the field electrode and the drift region and between the field electrode and the compensation. The field electrode dielectric includes a first opening through which the field electrode is coupled to drift region and a second opening through which the field electrode is coupled to the compensation region.
