An optoelectronic device including a substrate having a surface, openings which extend in the substrate from the surface, and semiconductor elements, each semiconductor element partially extending into one of the openings and partially outside said opening, the height of each opening being at least 25 nm and at most 5 &#x3bc;m and the ratio of the height to the smallest diameter of each opening being at least 0.5 and at most 15.

Optoelectronic device having semiconductor elements

An optoelectronic device comprises a substrate; pads on a surface of the substrate; semiconductor elements, each element resting on a pad; a portion covering at least the lateral sides of each pad, the portion preventing the growth of the semiconductor elements on the lateral sides; and a dielectric region extending in the substrate from the surface and connecting, for each pair of pads, one of the pads in the pair to the other pad in the pair. A method of manufacturing an optoelectronic device is also disclosed.
