Abstract
A nitride semiconductor device includes a horizontal switching device that includes a substrate, a channel forming layer, a source region, a drain region and a gate region. The source region and the drain region are arranged apart from each other in one direction along a plane of the substrate. The gate region is formed of a p-type semiconductor layer and is arranged between the source region and the drain region. The gate region is divided into multiple parts in a perpendicular direction along the plane of the substrate, the perpendicular direction being perpendicular to an arrangement direction in which the source region and the drain region are arranged. Accordingly, on-resistance is decreased while securing high breakdown voltage.
