Abstract:
1. A method of manufacturing a light emitting diode, comprising: forming a laser lift-off (LLO) layer comprising at least one of GaN, InGaN, AlGaN and InAlGaN on a nitride semiconductor substrate; forming a first semiconductor layer on the laser lift-off layer; forming an active layer and a second semiconductor layer on the first semiconductor layer; bonding a carrier to a surface of the second semiconductor layer; carrying out a laser lift-off process in which the laser beam is irradiated on the LLO layer through the nitride semiconductor substrate to separate the nitride semiconductor substrate; forming a metallic support on of the first semiconductor layer on which the nitride semiconductor substrate is separated; removing the carrier formed on the surface of the second semiconductor layer; forming a first electrode on the surface of the second semiconductor layer on which the carrier is removed; and forming a second electrode on the metallic support, wherein the LLO layer is completely removed by irradiating the laser beam, wherein the carrier comprises any one of a glass substrate, a sapphire substrate, a silicon substrate, a ZnO substrate, and a nitride semiconductor substrate, or a template substrate in which at least one of GaN, InGaN, AlGaN, and AlInGaN is laminated on anyone of a glass substrate, a sapphire substrate, a silicon substrate, a ZnO substrate, and a nitride semiconductor substrate.
