Patent ID: 8535962

Claim:
A method for making a light-emitting microelectronic device, the method comprising: growing, on a continuous substrate metal layer having a thickness between 10 μm and 10 mm and belonging to a metal support, a plurality of wires based on one or plural semi-conducting materials, each wire being individually configured to emit light radiation and being formed of a first portion that is based on GaN and n-doped, said first portion being in contact with the continuous substrate metal layer, each wire being further formed of a second portion on said first portion, said second portion being a quantum well portion forming a light emitting active zone, and of a third portion on said second portion, said third portion being based on GaN and p-doped, wherein the continuous substrate metal layer reflects the light radiation emitted by the plurality of wires; and forming at least one electrically conducting contact area on at least one of the wires.
