Abstract:
1. A method for manufacturing a light-emitting diode (LED), comprising: forming a first semiconductor layer; forming a light-emitting layer on the first semiconductor layer; forming a second semiconductor layer on the light-emitting layer; forming a first electrode and a second electrode on top of said first semiconductor layer and said second semiconductor layer respectively, so as to form a LED die, wherein the first electrode is thicker than the second electrode; forming metal pads on top of said first electrode and said second electrode of said LED die, wherein each of the metal pads has a side surface; and forming a fluorescent layer on a surface of said LED die and on the periphery of said metal pads and filling a gap between said metal pads with the fluorescent layer, said fluorescent layer failing to cover said metal pads, said fluorescent layer being in direct contact with the side surfaces of the metal pads; wherein the top surfaces of the metal pads are formed on the same plane in a section view of the light-emitting diode, wherein the thickness of the fluorescent layer is greater than 30 μm, and wherein the step of forming said fluorescent layer on said LED die is performed by first forming a mask on said metal pads, the material of the mask is an organic polymer material, and the mask is manufactured by lithography or screen-printing.
