An optoelectronic device including a substrate having opposite first and second surfaces; insulation trenches extending through the substrate, surrounding portions of the substrate and electrically insulating the portions from each other, each insulation trench being filled with at least one electrically insulating block and a gaseous volume or being filled with an electrically conductive element electrically isolated from the substrate; at least one light-emitting diode resting on the first surface for each portion of the substrate, the light-emitting diodes comprising wired, conical, or frustoconical semiconductor elements; an electrode layer covering at least one of the light-emitting diodes and a conductive layer overlying the electrode layer around the light-emitting diodes; and a layer encapsulating the light-emitting diodes and covering the entire first surface.

Optoelectronic device comprising light-emitting diodes

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.
