  • Patent number: 8957427
    Abstract: A method of forming a ZnO layer on a substrate and an LED including a ZnO layer formed by the method are provided. The ZnO layer is formed by using a Successive Ionic Layer Adsorption and Reaction (SILAR) process. The SILAR process includes: applying a first solution to a substrate comprising GaN, to form an inner ionic layer on the substrate and an outer ionic layer on the inner ionic layer; performing a first washing operation on the substrate to remove the outer ionic layer; and applying a second solution to the washed substrate to convert the inner ionic layer into a ZnO oxide layer.
