    Abstract: An HEMT includes a gallium nitride layer. An aluminum gallium nitride layer is disposed on the gallium nitride layer. A gate is disposed on the aluminum gallium nitride layer. The gate includes a P-type gallium nitride and a schottky contact layer. The P-type gallium nitride contacts the schottky contact layer, and a top surface of the P-type gallium nitride entirely overlaps a bottom surface of the schottky contact layer. A protective layer covers the aluminum gallium nitride layer and the gate. A source electrode is disposed at one side of the gate, penetrates the protective layer and contacts the aluminum gallium nitride layer. A drain electrode is disposed at another side of the gate, penetrates the protective layer and contacts the aluminum gallium nitride layer. A gate electrode is disposed directly on the gate, penetrates the protective layer and contacts the schottky contact layer.
