1. Method of manufacturing an optoelectronic device comprising light-emitting diodes comprising the forming of three-dimensional semiconductor elements made of a III-V compound, each comprising a lower portion and an upper portion, and, for each semiconductor element, the forming of an active area covering the top of the upper portion and the forming of at least one semiconductor layer of the III-V compound covering the active area, characterized in that the upper portions are formed by vapor deposition at a pressure smaller than 1.33 mPa.
