Patent ID: 8754468

Claim:
A lateral power semiconductor component comprising: a front side; a rear side; a lateral edge; an inner region with a MOS structure; an outer region interposed between the inner region and the lateral edge; a drift zone of a first conductivity type extending from the inner region into the outer region; a source zone of the first conductivity type disposed in the inner region; a body zone of a second conductivity type opposite the first conductivity type disposed in the inner region; a drain zone of the first conductivity type disposed in the inner region; a gate which forms the MOS structure with the drift zone, the source zone and the body zone; and a first horizontally extending field plate disposed above each semiconductor region of the power semiconductor component in the outer region, the first field plate forming a first plate capacitor structure with a first edge plate disposed under the first field plate in the outer region, wherein the first edge plate is a highly doped semiconductor material spaced apart from the drain zone and electrically connected to one of a source potential and a drain potential of the power semiconductor component.
