Abstract: A method of manufacturing an optoelectronic device including assemblies of light-emitting diodes (LED) having first and second assemblies and first blocks made of a first photoluminescent material, each covering one of the first assemblies. The method includes the forming of a layer covering the first and second assemblies, the delimiting of first openings in the layer to expose the first assemblies, the filling of the first openings with the first material, and the performing of a chemical-mechanical polishing to delimit the first blocks.

Abstract: A method for transferring a device from a first substrate to a second substrate by way of a manipulation substrate. The method includes bonding the device to the manipulation substrate by way of an assembly layer at a bonding surface, partially etching the assembly layer so as to conserve a narrow portion interposed between the device and the manipulation substrate, the narrow portion having a cross section strictly smaller than the bonding surface, the method being characterized in that the assembly layer is formed beforehand on the manipulation substrate and exclusively on the manipulation substrate.

Abstract: A method for selectively filling, with a filling liquid, a first cavity from among a plurality of cavities, each cavity opening out at a front face of a substrate. The method includes a processing step for altering the surface energy of the first internal surface of the first cavity or the surface energy of the second internal surfaces of the other cavities, such that the first surface has a first surface energy and the second surfaces have a second surface energy and a step including a sequence for spreading the filling liquid, the first energy and the second energy being adjusted such that the first and the second surfaces exert an attracting effect and a repelling effect, respectively, on the liquid.
