Patent ID: 11923464
Assignee: NOVEL CRYSTAL TECHNOLOGY, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A Schottky barrier diode, comprising:
a semiconductor layer comprising a Ga2O3-based single crystal;
an anode electrode that forms a Schottky junction with the semiconductor layer and is configured so that a portion in contact with a surface of the semiconductor layer comprises Mo or W; and
a cathode electrode,
wherein the surface of the semiconductor layer in contact with the anode electrode is configured such that a turn-on voltage of the Schottky barrier diode is not less than 0.3 V and not more than 0.5 V, and
wherein the surface of the semiconductor layer in contact with the portion of the anode electrode comprising Mo or W is treated with a sulfuric acid/hydrogen peroxide mixture.
