Abstract
A GaN-based diode may include an intrinsic GaN-based semiconductor layer, GaN-based semiconductor layers configured to have a first conductivity type and bonded to the intrinsic GaN-based semiconductor layer. A first electrode made of metal is placed on a surface opposite a surface bonded to the GaN-based semiconductor layers of the intrinsic GaN-based semiconductor layer; a second electrode is placed on a surface opposite to a surface bonded to the intrinsic GaN-based semiconductor layer of the GaN-based semiconductor layers of the first conductivity type. Voltage-resistant layers configured to have a second conductivity type are formed in regions of the intrinsic GaN-based semiconductor layer that come in contact with edges of the first electrode.
