Patent ID: 7838970

Claim:
A semiconductor component comprising: contact-making regions including first and second contact-making regions; a semiconductor volume disposed between the first and the second contact-making regions, the semiconductor volume comprising first and second emitter zones, a base zones and a field stop zones, and configured to provide a current flow between the first contact-making region and the second contact-making region, the semiconductor volume including a doped zone, said doped zone being embedded in said first emitter zone, so as to adjoin a first region and a second region of the first emitter zone, the first and second regions of the first emitter zone being of the same dopant type as said doped zone and the doping concentration of said doped zone being higher than the doping concentrations of the first and second regions of the first emitter zone, the first emitter zone being provided on the base zone and on the second emitter zone the base zone and the second emitter zone being of a different dopant type than said doped zone, the doped zone configured such that a ratio of a conductivity in one or more directions which are different from a main current flow direction to a conductivity of the main current flow direction is increased, and such that a local flow cross-section of a locally elevated current flow caused by current splitting is increased at least in partial regions of the semiconductor volume, and said doped zone extending to all regions of the semiconductor volume that are intended to be included by the current flow such that the current flow reaches regions of the semiconductor volume which it would not reach or would reach only in a low concentration without the provision of the doped zone.
