A semiconductor component comprising:
- a drift zone of a first conduction type;
- and
- at least one Schottky metal zone arranged in the drift zone.
An integrated circuit comprising:
- a semiconductor body;
- a drift zone of a first conduction type, said drift zone being arranged in the semiconductor body;
- a plurality of Schottky metal zones arranged at a distance from one another in a current flow direction of the component in the drift zone;
- and
