專利摘要(英)
A semiconductor power device and a manufacturing method thereof are provided. The semiconductor power device includes a substrate, a buffer layer, a nitride channel layer, a source, a drain, a barrier layer, a first etching stop layer, a first passivation layer, a second etching stop layer, a second passivation layer, a gate structure, a spacer, and a field plate structure. The buffer layer is disposed on the substrate. The nitride channel layer is disposed on the buffer layer. The source and the drain are disposed on the nitride channel layer. The barrier layer is disposed on the nitride channel layer between the source and the drain. The first etching stop layer is disposed on the barrier layer, the source and the drain. The first passivation layer is disposed on the first etching stop layer. The second etching stop layer is disposed on the first passivation layer. The second passivation layer is disposed on the second etching stop layer. The gate structure is disposed in the second passivation layer, the second etching stop layer and the first passivation layer. The spacer is disposed between the gate structure and the second passivation layer and the second etching stop layer. The field plate structure is disposed in the second passivation layer. A two-dimensional electron gas is located in the nitride channel layer between the source and the drain, and is adjacent to an interface between the nitride channel layer and the barrier layer.
