Patent abstract

Provided are a light-emitting element and a light-emitting device, and methods of fabricating the same. The method of fabricating a light-emitting element includes forming a buffer layer on a substrate and forming photonic crystal patterns and a pad pattern on the buffer layer. Each of the pad pattern and the photonic crystal patterns are made of a metal material, and the pad pattern is physically connected to the photonic crystal patterns. Forming a light-emitting structure includes sequentially stacking a first conductive pattern of a first conductivity type, a light-emitting pattern, and a second conductive pattern of a second conductivity type on the buffer layer. And the method also includes forming a first electrode that is electrically connected to the first conductive pattern and forming a second electrode that is electrically connected to the second conductive pattern.
