摘要： The present invention discloses a method for lift-off of an LED substrate. By eroding the sidewall of a GaN epitaxial layer, cavity structures are formed, which may act in cooperation with a non-fully filled patterned sapphire substrate from epitaxial growth to cause the GaN epitaxial layer to separate from the sapphire substrate.

摘要： The invention discloses a light-emitting diode. In an embodiment, the light-emitting diode includes a substrate, a first doping type semiconductor layer, a second doping type semiconductor layer, a light-emitting layer and plural laminated structures. The first doping type semiconductor layer, the light-emitting layer and the second doping type semiconductor layer are formed on the substrate in sequence. The plural laminated structures are formed on the top surface of the second doping type semiconductor layer such that the top surface is partially exposed. Each laminated structure consists of plural transparent insulating layers which have their respective refractive indices. Additionally, each of the laminated structures is formed in a way of upwardly stacking the transparent insulating layers in sequence with the refractive indices of the transparent insulating layers decreasing gradually, so as to enhance the light-extraction efficiency and the lighting efficiency of the light-emitting diode.

摘要： The invention discloses a light-emitting diode, including a substrate, a first conductive type semiconductor layer, a second conductive type semiconductor layer, a light-emitting layer and plural laminated structures. The first conductive type semiconductor layer, the light-emitting layer and the second conductive type semiconductor layer are formed on the substrate in sequence. The plural laminated structures are formed on the upper surface of the second conductive type semiconductor layer such that the upper surface is partially exposed. Each laminated structure consists of at least one first insulated layer with a high refractive index and at least one second insulated layer with a low refractive index, where the at least one first insulated layer and the at least one second insulated layer are alternately formed to obtain said each laminated structure. Thereby, light emitted from the light-emitting layer can be reflected by the laminated structures to enhance the light-extraction efficiency.
