    摘要: An integrated circuit device includes a semiconductor body fitted with a first electrode and a second electrode on opposite surfaces. A control electrode on an insulating layer controls channel regions of body zones for a current flow between the two electrodes. A drift section adjoining the channel regions comprises drift zones and charge compensation zones. A part of the charge compensation zones includes conductively connected charge compensation zones electrically connected to the first electrode. Another part includes nearly-floating charge compensation zones, so that an increased control electrode surface has a monolithically integrated additional capacitance CZGD in a cell region of the semiconductor device.

    摘要: A lateral power semiconductor component has a front side, a rear side and a lateral edge. The component further includes a drift zone of a first conductivity type, a source zone of the first conductivity type, a body zone of a second conductivity type opposite the first conductivity type, and a drain zone of the first conductivity type. A gate forms a MOS structure with the drift zone, the source zone and the body zone. A horizontally extending field plate above each semiconductor region of the power semiconductor component forms a plate capacitor structure with an edge plate lying under the field plate. The edge plate includes a highly doped semiconductor material and is electrically connected to one of a source potential and a drain potential of the power semiconductor component.

    摘要: A semiconductor component includes a semiconductor body having an edge with an edge zone of a first conductivity type. Charge compensation regions of a second conductivity type are embedded into the edge zone, with the charge compensation regions extending from a top side of the semiconductor component vertically into the semiconductor body. For the number Ns of charge carriers present in a volume Vs between two charge compensation regions that are adjacent in a direction perpendicular to the edge, and for the number Np of charge carriers present in a volume Vp between two charge compensation regions that are adjacent in a direction parallel to the edge, Np>Ns holds true.
