Abstract

See full text

In one embodiment, a semiconductor device includes a semiconductor substrate, a device portion disposed in the semiconductor substrate, and a junction terminal portion disposed in the semiconductor substrate and having an annular shape surrounding the device portion. The junction terminal portion includes first semiconductor regions of a first conductivity type and second semiconductor regions of a second conductivity type. The first semiconductor regions are adjacent to each other in a circumferential direction of the annular shape of the junction terminal portion, and have a width decreasing with progressing in a direction away from the device portion. The second semiconductor regions are disposed between the first semiconductor regions, and have a width increasing with progressing in the direction away from the device portion.
