Patent ID: 7968919

Claim:
An integrated circuit including a charge compensation component comprising: a first electrode; a counterelectrode; and a vertically extending drift path between the electrodes with; drift zones of a first conduction type; and charge compensation zones of a complementary conduction type with respect to the first conduction type; and a drift path layer doping comprising a volume integral of doping locations of a horizontal drift path layer of the vertically extending drift path including the drift zone regions and charge compensation zone regions arranged in the drift path layer; and wherein the drift path layer defines a doping profile in which portions of the drift path layer adjacent the first electrode and the counterelectrode have a first doping level, and a portion of the drift path layer in a central region between the first electrode and the counterelectrode has a second doping level, and wherein the first doping level is higher than the second doping level such that doping levels at a beginning and an end of the drift path are higher than a doping level at a center of the drift path, wherein the doping profile linearly increases from the second doping level to the first doping level.
