Filed: 2017-10-26
Abstract: To provide a Schottky barrier diode that is less likely to generate dielectric breakdown caused by electric field concentration.SOLUTION: A Schottky barrier diode comprises: a semiconductor substrate 20 formed of gallium oxide; a drift layer 30 provided on the semiconductor substrate 20 and formed of gallium oxide; an anode electrode 40 Schottky-contacted with the drift layer 30; and a cathode electrode 50 ohmic-contacted with the semiconductor substrate 20. The drift layer 30 has a plurality of trenches 60 provided at positions overlapped with the anode electrode 40 in a plan view. A width W2 of a trench 60a located at an end part, among the plurality of trenches 60, is selectively enlarged. Thereby, a curvature radius of a bottom part of the trench 60a is enlarged, or an edge part configured by the bottom part is separated into two parts in a cross sectional view of the trench 60a. As a result, an electric field applied to the bottom part of the trench 60a located at the end part is alleviated, and thus, dielectric breakdown is less likely to be generated.SELECTED DRAWING: Figure 1
