Abstract

See full text

According to an embodiment, a semiconductor device includes at least two control electrodes, a plurality of semiconductor layers and an insulating film. Each control electrode extends in a first direction. The semiconductor layers are provided between the control electrodes, and arranged in the first direction. Each semiconductor layer extends in a second direction orthogonal to the first direction. The insulating film covers side surfaces of the semiconductor layers, and is disposed between the control electrodes. Each semiconductor layer has a side surface that includes at least one curved surface swelling in a direction from a center of the semiconductor layer to the insulating film.
