Abstract
A method of manufacturing a light-emitting device includes: providing a substrate; forming a light-emitting structure comprising an active layer on the substrate; forming a protective layer having a first thickness on the light-emitting structure; etching the protective layer such that the protective layer has a second thickness less than the first thickness; and patterning the protective layer.
