ABSTRACT:
An LED chip includes a substrate, a semiconductor device layer, a wall structure, and a number of electrodes. The semiconductor device layer is disposed on the substrate and includes a first-type doped semiconductor layer disposed on the substrate, an active layer disposed on a portion of the first-type doped semiconductor layer, and a second-type doped semiconductor layer disposed on the active layer and having a first top surface. The wall structure is disposed on the first-type doped semiconductor layer that is not covered by the active layer and surrounds the active layer. Besides, the wall structure has a second top surface higher than the first top surface of the second-type doped semiconductor layer. Additionally, the electrodes are disposed on and electrically connected with the first-type doped semiconductor layer and the second-type doped semiconductor layer.
