Provided are a method of fabricating a light-emitting apparatus with improved light extraction efficiency and a light-emitting apparatus fabricated using the method. The method includes: preparing a monocrystalline substrate; forming an intermediate structure on the substrate, the intermediate structure comprising a light-emitting structure which comprises a first conductive pattern of a first conductivity type, a light-emitting pattern, and a second conductive pattern of a second conductivity type stacked sequentially, a first electrode which is electrically connected to the first conductive pattern, and a second electrode which is electrically connected to the second conductive pattern; forming a polycrystalline region, which extends in a horizontal direction, by irradiating a laser beam to the substrate in the horizontal direction such that the laser beam is focused on a beam-focusing point within the substrate; and cutting the substrate in the horizontal direction along the polycrystalline region.
