Abstract
An optoelectronic device including a semiconductor substrate including first and second opposing faces, a first set of first light-emitting diodes resting on a first portion of the substrate and including conical or frustoconical wire-like semiconductor elements, a first electrode covering each first light-emitting diode, a first conductive portion insulated from the substrate, extending through the substrate and connected to the first electrode; a second set of second light-emitting diodes resting on a second portion of the substrate and including conical or frustoconical wire-like semiconductor elements, a second electrode covering each second light-emitting diode, a second conductive portion insulated from the substrate and connected to the second electrode, and a first conductive element connecting the first conductive portion to the second portion of the substrate on the side of the second face.
