Claim Text:
1. A semiconductor component comprising: a semiconductor body comprising a first side and a second side, and a first semiconductor layer having a basic doping of a first conductivity type; at least one active component zone of a second conductivity type, which is complementary to the first conductivity type, in the first semiconductor layer; a cell array with a plurality of trenches, each trench including a field electrode and a field electrode dielectric, wherein in the cell array the at least one active component zone of the second conductivity type is electrically connected to an electrode, the cell array including an edge region, wherein the edge region of the cell array includes at least an outermost trench of the cell array and a trench of the cell array adjacent to the outermost trench; and at least one cell array edge zone of the second conductivity type, the at least one cell array edge zone arranged only in the edge region of the cell array at least partially below and having an interface with at least one trench in the edge region of the cell array, wherein the cell array edge zone is spaced apart from the first side of the semiconductor body, wherein the semiconductor component is implemented as a MOS transistor and comprising in the inner region a plurality of transistor cells, each transistor cell comprising: a source zone of a first conductivity type, a drift zone of the first conductivity type, and a body zone of the second conductivity type between the source zone and the drift zone; a gate electrode being disposed adjacent to the body zone and being insulated against the body zone by a gate dielectric, and wherein the gate electrodes of the transistor cells are arranged in the same trenches as the field electrodes, the field electrodes extending deeper into the semiconductor body than the gate electrodes.
