Abstract:
The semiconductor device of the present invention includes a first conductivity type semiconductor layer made of a wide bandgap semiconductor and a Schottky electrode formed to come into contact with a surface of the semiconductor layer, and has a threshold voltage V th  of 0.3 V to 0.7 V and a leakage current J r  of 1×10 −9  A/cm 2  to 1×10 −4  A/cm 2  in a rated voltage V R .

Claim (Index 10):
A semiconductor device, comprising:\n a first conductivity type semiconductor layer made of a wide bandgap semiconductor; a Schottky electrode formed to come into contact with a surface of the semiconductor layer; a field region surrounding the Schottky electrode; and an annular trench formed on the field region and surrounding the Schottky electrode, wherein the semiconductor layer has a first part of a first conductivity type to which a first electric field is applied when a reverse voltage is applied and a second part of the first conductivity type to which a second electric field relatively higher than the first electric field is applied, the Schottky electrode includes a first electrode that forms a first Schottky barrier with the first part and a second electrode that forms a second Schottky barrier with the second part, the second Schottky barrier being relatively higher than the first Schottky barrier, a plurality of the annular trenches are arranged at intervals, and a width of a part sandwiched between the annular trenches adjoining each other becomes greater in proportion to an approach to a far side from a near side with respect to the Schottky electrode.
