Patent ID: 8513039

Claim:
A method for fabricating a semiconductor lighting chip, comprising steps: providing a substrate; forming a first etching layer on the substrate; forming a connecting layer on the first etching layer; forming a second etching layer on the connecting layer; forming a lighting structure on the second etching layer; and etching the first etching layer, the connecting layer, the second etching layer and the lighting structure, wherein an etching rate of the first etching layer and the second etching layer is larger than that of the connecting layer and the lighting structure, thereby to form the connecting layer and the lighting structure each having an inverted frustum-shaped structure; wherein when the second etching layer is etched, lateral sides of the second etching layer are etched to form first clearances between the lighting structure and the connecting layer, thereby to expose a bottom surface of the lighting structure; wherein when the first etching layer is etched, lateral sides of the first etching layer is etched to form second clearances between the substrate and the connecting layer, thereby to expose a bottom surface of the connecting layer.
