Patent ID: 8178377

Claim:
A method for fabricating a light emitting diode chip, comprising: forming a first patterned photoresist layer on a substrate, wherein the first patterned photoresist layer comprises a first photoresist block and a second photoresist block, and a thickness of the first photoresist block is thinner than a thickness of the second photoresist block; removing partially a surface of the substrate with the first patterned photoresist layer as a mask to form a first patterned substrate; reducing a thickness of the first patterned photoresist layer until the first photoresist block is removed completely, wherein the remaining second photoresist block partially exposes the first patterned substrate; removing partially the first patterned substrate with the remaining second photoresist block as a mask to form a second patterned substrate; and forming a semiconductor device layer including a first type semiconductor material layer, a light emitting layer and a second type semiconductor material layer, a current spreading layer and a plurality of electrodes sequentially on the second patterned substrate, wherein the plurality of electrodes are electrically connected with the semiconductor device layer and the current spreading layer.
