Abstract:
1. A semiconductor device comprising: a first semiconductor layer which is formed above a substrate; a Schottky electrode and an ohmic electrode which are formed in direct contact with the first semiconductor layer to be spaced from each other; a second semiconductor layer which is formed in direct contact with a top surface of the first semiconductor layer to cover the first semiconductor layer with the Schottky electrode and the ohmic electrode exposed, and has a larger band gap than that of the first semiconductor layer; and an insulating film which is formed in direct contact with the second semiconductor layer; wherein the side of the Schottky electrode facing the ohmic electrode is configured to extend over the top surface of the second semiconductor layer toward the ohmic electrode, and is configured to extend over the top surface of the insulating film toward the ohmic electrode.
