Abstract:
An embodiment relates to a light-emitting element, a method for producing same, a light-emitting element package, and a lighting system. A light-emitting element according to the embodiment may comprise: a first conductive semiconductor layer (112); a second conductive semiconductor layer (116) disposed below the first conductive semiconductor layer (112); an active layer (114) disposed between the first conductive semiconductor layer (112) and the second conductive semiconductor layer (116); a plurality of holes (H) exposing parts of the first conductive semiconductor layer (112) to the bottom surface of the second conductive semiconductor layer (116) by penetrating the second conductive semiconductor layer (116) and the active layer (114); first contact electrodes (160) electrically connected to the first conductive semiconductor layer (112) from the bottom surface of the second conductive semiconductor layer (116) through the plurality of holes (H); an insulation layer (140) disposed between the first contact electrode (160) and the plurality of holes (H); a bonding layer (156) electrically connected to the first contact electrodes (160); a support member (158) disposed below the bonding layer (156); a second contact electrode (132) electrically connected to the second conductive semiconductor layer (116); and a first current-spreading semiconductor layer (191) inside the first conductive semiconductor layer (112) above the first contact electrode (160).
