Patent ID: 10319879

Abstract:
A semiconductor structure includes a first-type semiconductor layer, a second-type semiconductor layer, a light emitting layer and a hole supply layer. The light emitting layer is disposed between the first-type semiconductor layer and the second-type semiconductor layer. The hole supply layer is disposed between the light emitting layer and the second-type semiconductor layer, and the hole supply layer includes a first hole supply layer and a second hole supply layer. The first hole supply layer is disposed between the light emitting layer and the second hole supply layer, and a chemical formula of the first hole supply layer is Alx1Iny1Ga1-x1-y1N, wherein 0≤x1<0.4, and 0≤y1<0.4. The second hole supply layer is disposed between the first hole supply layer and the second-type semiconductor layer, a chemical formula of the second hole supply layer is Alx2Iny2Ga1-x2-y2N, wherein 0≤x2<0.4, 0≤y2<0.4, and x1>x2.
