A method for manufacturing an indium gallium nitride/gallium nitride quantum-well pyramid is provided to improve upon the complexity of the conventional method for manufacturing light-emitting diode die. The method for manufacturing an indium gallium nitride/gallium nitride quantum-well pyramid includes performing a first epitaxial reaction and then a second epitaxial reaction on a substrate under 600-650&#xb0; C. to form a gallium nitride pyramid, growing an first indium gallium nitride layer on an end face of the gallium nitride pyramid, where the end face is away from the substrate, and growing a first gallium nitride layer on the first indium gallium nitride layer. A flux ratio of nitrogen to gallium of the first epitaxial reaction is 25:1-35:1, and a flux ratio of nitrogen to gallium of the second epitaxial reaction is 130:1-150:1.
