Claim Text:
1. A semiconductor device, comprising: a semiconductor substrate comprising a plurality of switchable cells defining an active area of the semiconductor device, an outer rim, and an edge termination region arranged between the switchable cells and the outer rim, each of the switchable cells comprising a body region, a gate electrode structure and a source region; a source metallization in ohmic contact with the respective source region of the switchable cells; and a gate metallization in ohmic contact with the respective gate electrode structure of the switchable cells; wherein the active area defined by the switchable cells comprises at least a first switchable region and at least a second switchable region, wherein the switchable cells of the first switchable region have a first threshold voltage, and wherein the switchable cells of the second switchable region have a second threshold voltage which is higher than the first threshold voltage, and wherein an area occupied by the first switchable region is larger than an area occupied by the second switchable region.
