摘要：
A semiconductor device includes a III-nitride substrate of a first conductivity type, a first III-nitride epitaxial layer of the first conductivity type coupled to the III-nitride substrate, and a first III-nitride epitaxial structure coupled to a first portion of a surface of the first III-nitride epitaxial layer. The first III-nitride epitaxial structure has a sidewall. The semiconductor device further includes a second III-nitride epitaxial structure of the first conductivity type coupled to the first III-nitride epitaxial structure, a second III-nitride epitaxial layer of the first conductivity type coupled to the sidewall of the second III-nitride epitaxial layer and a second portion of the surface of the first III-nitride epitaxial layer, and a third III-nitride epitaxial layer of a second conductivity type coupled to the second III-nitride epitaxial layer. The semiconductor device also includes one or more dielectric structures coupled to a surface of the third III-nitride epitaxial layer.
