发明名称 Method for producing light-emitting diode
摘要 The present invention provides a method for producing a light-emitting diode, the method comprising a lamination step of forming a laminated semiconductor layer by sequentially laminating an n-type semiconductor layer, a light-emitting layer and a p-type semiconductor layer onto a substrate, as well as forming a plurality of reflective p-type electrodes on top of the p-type semiconductor layer, a plating step of forming a seed layer that covers the reflective p-type electrodes and the p-type semiconductor layer, and fowling a plating layer on top of the seed layer, a removal step of removing the substrate from the n-type semiconductor layer, thereby exposing a light extraction surface of the n-type semiconductor layer, and an electrode formation step of performing dry etching of the light extraction surface of the n-type semiconductor layer using an etching gas containing the same element as a dopant element within the n-type semiconductor layer, and subsequently forming an n-type electrode on the light extraction surface.
