Abstract

An optoelectronic device including a support having a rear surface and a front surface opposite each other, a plurality of nucleation conductive strips forming first polarization electrodes, an intermediate insulating layer covering the nucleation conductive strips, a plurality of diodes, each of which having a first, three-dimensional doped region and a second doped region, and a plurality of top conductive strips forming second polarization electrodes and resting on the intermediate insulating layer, each top conductive strip being disposed in such a way as to be in contact with the second doped regions of a set of diodes of which the first doped regions are in contact with different nucleation conductive strips.
