Original Abstract Submitted
Disclosed herein is a junction barrier Schottky diode includes a semiconductor substrate made of gallium oxide, a drift layer made of gallium oxide and provided on the semiconductor substrate, an anode electrode brought into Schottky contact with the drift layer, and a cathode electrode brought into ohmic contact with the semiconductor substrate. The drift layer has a center trench filled with the anode electrode and a semiconductor material having a conductivity type opposite to that of the drift layer. A bottom surface of the center trench contacts the semiconductor material without being in contact with the anode electrode. At least a part of a side surface of the center trench is brought into Schottky contact with the anode electrode.
