    摘要: The present invention discloses a junction barrier Schottky (JBS) diode and a manufacturing method thereof. The JBS diode includes: an N-type gallium nitride (GaN) substrate; an aluminum gallium nitride (AlGaN) barrier layer, which is formed on the N-type GaN substrate; a P-type gallium nitride (GaN) layer, which is formed on or above the N-type GaN substrate; an anode conductive layer, which is formed at least partially on the AlGaN barrier layer, wherein a Schottky contact is formed between part of the anode conductive layer and the AlGaN barrier layer; and a cathode conductive layer, which is formed on the N-type GaN substrate, wherein an ohmic contact is formed between the cathode conductive layer and the N-type GaN substrate, and the cathode conductive layer is not directly connected to the anode conductive layer.
