Patent ID: 7872300

Claim:
A vertical power semiconductor component comprising a front side, a rear side and an edge, the power semiconductor component further comprising: a semiconductor body comprising at least one drift zone of the first conductivity type, a multiplicity of source zones of the first conductivity type, a multiplicity of body zones of the second conductivity type, and a drain zone of the first conductivity type, at least one gate which forms a MOS structure with a drift zone, with at least one of the source zones and with at least one of the body zones, compensation pillars of the second conductivity type, which project into the drift zone from above in contact with the body zones, between the edge and the MOS structure an edge termination, the edge being at the same potential as the drift zone, and the edge termination reducing voltage between the edge and the source zone, a horizontally extending edge plate provided at the front side between the edge and the edge termination, a field plate lying above the edge plate, the field plate being connected to an edge termination pillar of the edge termination and electrically isolated from a source electrode connected to the source zones; a first insulation layer arranged between the edge plate and the field plate, a second insulation layer arranged between the field plate and a conductive layer lying above the field plate, the conductive layer being isolated from the source electrode, wherein the field plate terminates before the edge and is covered laterally by an insulation layer, the conductive layer extends, at the edge, down onto the edge plate to form an electrical contact with the edge plate, the field plate forms a first plate of a plate capacitor structure and the edge plate and the conductive layer form a second plate of the plate capacitor structure.
