Abstract

See full text

A method for fabricating a semiconductor light-emitting device includes fabricating a multilayer semiconductor structure on a first substrate, wherein the multilayer semiconductor structure comprises a first doped semiconductor layer, an MQW active layer, a second doped semiconductor layer, and a first passivation layer. The method further involves patterning and etching part of the first passivation layer to expose the first doped semiconductor layer. A first electrode is then formed, which is coupled to the first doped semiconductor layer. Next, the multilayer structure is bonded to a second substrate; and the first substrate is removed. A second electrode is formed, which is coupled to the second doped semiconductor layer. Further, a second passivation layer is formed, which substantially covers the sidewalls of multilayer structure and part of the surface of the second doped semiconductor layer which is not covered by the second electrode.
