Patent ID: 8222056

Claim:
A manufacturing method of a light-emitting diode, comprising: successively growing a first clad layer, an active layer and a second clad layer on a substrate; and patterning the first clad layer, the active layer and the second clad layer into a specified plane shape, and causing at least a part of an outer peripheral part of the active layer to protrude to an outside from at least one of the first clad layer and the second clad layer; wherein the first clad layer, the active layer and the second clad layer are patterned by dry etching; wherein at least one of the first clad layer and the second clad layer is side-etched with respect to the active layer, and at least the part of the outer peripheral part of the active layer protrudes to the outside from at least one of the first clad layer and the second clad layer; and wherein the side etching is performed by wet etching.
