Abstract
A semiconductor device includes a semiconductor layer of a first conductivity type, a plurality of first regions that are spaced apart from each other along a first direction by portions of the semiconductor layer, each of the first regions including a first semiconductor region of a second conductivity type, a second region between the first regions in the first direction, the second region including a second semiconductor region of the first conductivity type and a first insulator between the second semiconductor region and the semiconductor layer, and a third region between the first region and the second region, the third region including a third semiconductor region of the first conductivity type and a second insulator.
