Abstract:
1. A method for fabricating a light emitting diode chip, comprising: forming a semiconductor device layer on a substrate and a current spreading layer on the semiconductor device layer, wherein forming the semiconductor device layer and the current spreading layer comprises; forming a dielectric layer on the substrate to cover the semiconductor device layer and the current spreading layer: forming a patterned photoresist layer on the dielectric layer, wherein the 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 the dielectric layer to form a patterned dielectric layer with the patterned photoresist layer as a mask, wherein the patterned dielectric layer exposes a portion of the semiconductor device layer and a portion of the current spreading layer; reducing a thickness of the patterned photoresist layer until the first photoresist block is removed completely; forming an electrode material layer entirely; and removing the patterned photoresist layer to strip the electrode material layer thereon and form a plurality of electrodes, wherein the electrodes are electrically connected with the semiconductor device layer and the current spreading layer.
