More Information
Summary:A semiconductor device cell includes a semiconductor layer having a surface defining a series of parallel striations extending in a first direction. The semiconductor layer surface has a lower electrical resistance in the first direction than in a second direction orthogonal to the first direction. A channel region defines a set of first channel region segments extending in the first direction, and a set of second channel region segments extending in the second direction. The first channel region segments and the second channel region segments are arranged to maximize portions of the channel region extending in the first direction across the surface, and minimize portions of the channel region extending in the second direction, to reduce or minimize the effective electrical resistance of the channel region in operation.
