Abstract:
1. An MPS diode comprising: a III-nitride substrate having a first side and a second side opposing the first side, wherein the III-nitride substrate is characterized by a first conductivity type; a first III-nitride epitaxial layer coupled to the III-nitride substrate and characterized by the first conductivity type; a plurality of dopant sources coupled to the first III-nitride epitaxial layer and characterized by a second conductivity type; a second III-nitride epitaxial layer overlying portions of the first III-nitride epitaxial layer and overlying the plurality of dopant sources, wherein the second III-nitride epitaxial layer includes first regions characterized by the first conductivity type and second regions characterized by the second conductivity type; and a first metallic structure electrically coupled to the second III-nitride epitaxial layer, wherein the first metallic structure comprises Schottky contacts to the first regions and ohmic contacts to the second regions.
