Abstract
A light emitting device and a method of fabricating thereof are provided. The method of fabricating the light emitting device comprises: providing a substrate having a first major surface and a second major surface; forming a plurality of light-emitting stacks on the first major surface; forming an etching protection layer on each of the light emitting stacks; forming a plurality of holes by a discontinuous laser beam on the substrate; etching the plurality of holes; and slicing off the substrate along the plurality of holes to form a light emitting device. The light emitting device has a substrate wherein the sidewall of the substrate comprising a first area with a substantially flat surface and a second area with substantially textured surface.
