METHOD FOR FABRICATING SEMICONDUCTOR LIGHTING CHIP

摘要

A method for fabricating a semiconductor lighting chip includes steps: providing a substrate with an epitaxial layer, the epitaxial layer comprising a first semiconductor layer, a second semiconductor layer and an active layer located between the first semiconductor layer and the second semiconductor layer; dipping the epitaxial layer into an electrolyte to etch surfaces of the epitaxial layer and form a number of holes on the epitaxial layer; and forming electrodes on the epitaxial layer.
