The invention relates to a method for manufacturing an optoelectronic device () including wire-like, conical, or frustoconical semiconductor elements () predominantly comprising a III-V compound. Each semiconductor element extends along an axis and includes a portion (), the side surfaces () of which are covered with a shell () including at least one active region (), wherein the portions are created by continuous growth in a reactor, and wherein the temperature in the reactor varies in an uninterrupted manner from a first temperature value that favors growth of first crystallographic planes perpendicular to said axis, to a second temperature value that is strictly lower than the first temperature value and favors growth of second crystallographic planes parallel to said axis.

Optoelectronic device comprising three-dimensional semiconductor elements, and method for manufacturing said device

An optoelectronic device including a first integrated circuit that includes:&#x2014;a substrate, having first and second opposite surfaces; and&#x2014;groups of sets of light-emitting diodes resting on the first surface. The integrated circuit also includes:&#x2014;in the substrate, first side elements for electrically insulating portions of the substrate around each set; and&#x2014;for each group on the second surface, at least one first conductive contact, connected to the first terminal of the group, and one second conductive contact, connected to the second terminal of the group. The device includes a second integrated circuit containing:&#x2014;third and fourth opposite surfaces; and&#x2014;third conductive contacts, located on the third surface and electrically connected to the first and second conductive contacts. The first integrated circuit is attached onto the third surface of the second integrated circuit.
