Abstract
A method for producing optoelectronic devices, including the following successive steps: providing a substrate having a first face; on the first face, forming sets of light-emitting diodes including wire-like, conical or frustoconical semiconductor elements; covering all of the first face with a layer encapsulating the light-emitting diodes; forming a conductive element that is insulated from the substrate and extends through the substrate from the second face to at least the first face; reducing the thickness of the substrate; and cutting the resulting structure in order to separate each set of light-emitting diodes.
