  • Patent number: 8841151
    Abstract: A method of manufacturing a device based on LEDs includes the growth of semiconducting nanowires on a first electrode produced on an insulating face, and encapsulation thereof in planarizing material; the formation, on the planarizing material, of a second electrode with contact take-up areas. LEDs are formed by releasing a band of the first electrode around each take-up area, including forming a mask defining the bands on the second electrode, chemically etching the planarizing material, stopped so as to preserve planarizing material, chemically etching the portion of nanowires thus released, and then chemically etching the remaining planarizing material. A trench is formed along each of the bands as far as the insulating face and the LEDs are placed in series by connecting the take-up areas and bands of the first electrode.
