摘要: A semiconductor structure includes a III-nitride substrate having a top surface and an opposing bottom surface and a first III-nitride layer of a first conductivity type coupled to the top surface of the III-nitride substrate. The semiconductor structure also includes a second III-nitride layer of a second conductivity type coupled to the first III-nitride layer along a vertical direction and a third III-nitride layer of a third conductivity type coupled to the second III-nitride layer along the vertical direction. The semiconductor structure further includes a first trench extending through a portion of the third III-nitride layer to the first III-nitride layer, a second trench extending through another portion of the third III-nitride layer to the second III-nitride layer, and a first metal layer coupled to the second and the third III-nitride layers.
