Abstract
A semiconductor device includes a semiconductor layer, first and second electrodes, one or more gate electrodes, and an array of structures. The semiconductor layer has first and second sides opposite to each other in a first direction. The semiconductor layer is single crystal silicon. The array of structures is in the semiconductor layer and arranged in a second direction perpendicular to the first direction and along a [100] direction of the single crystal silicon and in a third direction that is perpendicular to the first direction and not perpendicular to the second direction. A first distance between first and second ones of the structures adjacent to each other in the third direction is less than a second distance between the first one and a third one of the structures adjacent to the first one in the second direction.
