Abstract
A method of manufacturing an optoelectronic device, comprising the successive steps of: providing a substrate at least partially made of a semiconductor material and having first and second opposite faces; forming a stack of semiconductor layers on the first face, said stack including third and fourth opposite faces, the fourth face being on the side of the substrate, said stack including light-emitting diodes; forming through openings in the substrate from the side of the second face, said openings being opposite at least part of the light-emitting diodes and delimiting walls in the substrate; forming conductive pads on the fourth face in at least some of the openings in contact with the stack; and forming photoluminescent blocks in at least some of the openings.
