Abstract
To provide a highly reliable semiconductor device having both an improved breakdown voltage and a reduced withstand voltage leakage current. An intermediate resistive field plate is comprised of a first intermediate resistive field plate coupled, at one end thereof, to an inner-circumferential-side resistive field plate and, at the other end, to an outer-circumferential-side resistive field plate and a plurality of second intermediate resistive field plates. The first intermediate resistive field plate has a planar pattern that is equipped with a plurality of first portions separated from each other in a first direction connecting the inner-circumferential resistive field plate to the outer-circumferential-side resistive field plate and linearly extending in a second direction orthogonal to the first direction, and repeats reciprocation along the second direction. The second intermediate resistive field plates are each connected with a first end portion on one side of the first portions and extend with a curvature.
