Patent ID: 10153394

Abstract:
A semiconductor structure includes a first-type doped semiconductor layer, a light emitting layer, a second-type doped semiconductor layer comprising AlxInyGa1-x-yN layers, at least one GaN based layer, and an ohmic contact layer. The light emitting layer is disposed on the first-type doped semiconductor layer, and the second-type doped semiconductor layer is disposed on the light emitting layer. The AlxInyGa1-x-yN layers stacked on the light emitting layer, where 0<x<1, 0≤y<1, and 0<x+y<1, and the GaN based layer interposed between two of the AlxInyGa1-x-yN layers, and the ohmic contact layer is disposed on the AlxInyGa1-x-yN layers.
