Abstract
Disclosed are a Schottky diode and a manufacturing method thereof. The Schottky diode includes a substrate, a first semiconductor layer, a heterostructure layer, and a passivation layer, where the passivation layer includes a first groove and a second groove, and the first groove and the second groove penetrate the passivation layer and expose the heterostructure layer; a second semiconductor layer, where the second semiconductor layer is located in the first groove, and the second semiconductor layer does not fully fill the first groove in a horizontal direction; a first electrode, where the first electrode is at least located on a heterostructure layer and the second semiconductor layer that are corresponding to the first groove; and a second electrode located in the second groove.
