Abstract
A nitride semiconductor device includes: a conductive layer; a protruding region of a nitride semiconductor provided on at least a part of an upper surface of the conductive layer; and an n-type drift layer provided above the conductive layer. The drift layer includes a tapered region having an upward tapered shape above the protruding region. The nitride semiconductor device further includes a p-type body layer adjacent to the tapered region of the drift layer. The drift layer and the body layer are an epitaxial layer.
