摘要
A method for enhancing electrical injection efficiency and light extraction efficiency of a light-emitting device is disclosed. The method includes the steps of: providing a site layer on the light-emitting device; placing a protection layer on the site layer; forming a cavity through the protection layer and the site layer; and growing a window layer in the cavity. The shape of the window layer can be well controlled by adjusting reactive temperature, reactive time, and N2/H2 concentration ratio of atmosphere such that light escape angle of the window layer can be changed.
