| titleOfInvention | Flip LED chip and forming method thereof |
| abstract | The invention provides a flip LED chip and a forming method thereof, wherein the forming method comprises the following steps: providing a substrate; forming an N-type semiconductor layer, an active layer and a P-type semiconductor layer; forming an opening exposing a part of the N-type semiconductor layer; p, N forming an electrode layer and an insulating reflecting layer; forming P, N an electrode structure. The flip LED chip comprises a substrate, an N-type semiconductor layer, an active layer and a P-type semiconductor layer; a P electrode layer is arranged on the P type semiconductor layer, and an N electrode layer is arranged on the N type semiconductor layer in the opening; the insulating reflecting layer covers the P-type semiconductor layer, the P electrode layer, the N-type semiconductor layer and the N electrode layer; and the P electrode structure is formed in the insulating reflecting layer and is electrically connected with the P electrode layer, and the N electrode structure is electrically connected with the N electrode layer. The flip LED chip has the beneficial effects that the insulating reflecting layer can reflect part of light to the substrate while playing a role of insulating and isolating, so that the light transmittance of the flip LED chip is increased. |
