Abstract:
1. A fabricating method of a light emitting diode chip, the fabricating method comprising: sequentially forming a first-type doped semiconductor material layer, a light emitting material layer, and a second-type doped semiconductor material layer on a substrate; patterning the second-type doped semiconductor material layer, the light emitting material layer, and the first-type doped semiconductor material layer, so as to form a first-type doped semiconductor layer, an active layer, and a second-type doped semiconductor layer, wherein the active layer is disposed on a portion of the first-type doped semiconductor layer, the second-type doped semiconductor layer is disposed on the active layer, and the second-type doped semiconductor layer has a first top surface; forming a wall structure in a form of a continuous pattern on the first-type doped semiconductor layer that is not covered by the active layer, wherein the wall structure surrounds the active layer and has a second top surface higher than the first top surface of the second-type doped semiconductor layer; and forming a plurality of electrodes on the first-type doped semiconductor layer and the second-type doped semiconductor layer.
