Abstract:
One embodiment provides a semiconductor component including a semiconductor body having a first side and a second side and a drift zone; a first semiconductor zone doped complementarily to the drift zone and adjacent to the drift zone in a direction of the first side; a second semiconductor zone of the same conduction type as the drift zone adjacent to the drift zone in a direction of the second side; at least two trenches arranged in the semiconductor body and extending into the semiconductor body and arranged at a distance from one another; and a field electrode arranged in the at least two trenches adjacent to the drift zone. The at least two trenches are arranged at a distance from the second semiconductor zone in the vertical direction, a distance between the trenches and the second semiconductor zone is greater than 1.5 times the mutual distance between the trenches, and a doping concentration of the drift zone in a section between the trenches and the second semiconductor zone differs by at most 35% from a minimum doping concentration in a section between the trenches.
