A method for producing optoelectronic devices, including the following successive steps: providing a substrate having a first face; on the first face, forming sets of light-emitting diodes including wire-like, conical or frustoconical semiconductor elements; covering all of the first face with a layer encapsulating the light-emitting diodes; forming a conductive element that is insulated from the substrate and extends through the substrate from the second face to at least the first face; reducing the thickness of the substrate; and cutting the resulting structure in order to separate each set of light-emitting diodes.

Method for producing optoelectronic devices comprising light-emitting diodes

An optoelectric device including microwires or nanowires on a support, each microwire or nanowire including at least one portion mainly containing a III-V compound in contact with the support, wherein the III-V compound is based on a first group-V element and on a second group-III element, wherein a surface of the support includes first areas of a first material promoting the growth of the III-V compound according to the polarity of the first element distributed in a second area of a second material promoting the growth of the compound according to the polarity of the second element, the microwires or nanowires being located on the first areas.

Optoelectric device with semiconductor microwires or nanowires and method for manufacturing the same

A stereolithography apparatus and an exposure system for a stereolithography apparatus, wherein light emitting diodes are used as light sources. The invention relates to aligning light from the light emitting diode and to the exchange and control of the light emitting diodes.
