METHOD AND SYSTEM FOR GALLIUM NITRIDE VERTICAL JFET WITH SEPARATED GATE AND SOURCE

摘要

A semiconductor structure includes a III-nitride substrate and a first III-nitride epitaxial layer of a first conductivity type coupled to the III-nitride substrate. The semiconductor structure also includes a first III-nitride epitaxial structure of the first conductivity type coupled to the first III-nitride epitaxial layer and a second III-nitride epitaxial structure of the first conductivity type coupled to the first III-nitride epitaxial structure. The semiconductor structure further includes a second III-nitride epitaxial layer coupled to the first III-nitride epitaxial structure. The second III-nitride epitaxial layer is of a second conductivity type and is not electrically connected to the second III-nitride epitaxial structure.
