Abstract
A process for fabricating an array of nanowires on the surface of a substrate, the nanowires comprising a portion capable of emitting radiation under action of an electrical or optical control and at least partially connected to one another electrically via a conductive upper layer, comprises steps allowing a subset of defective nanowires to be identified among active nanowires, the steps comprising: producing a layer of negative photoresist sensitive to the emission wavelength, covering the array of the nanowires; activating the array of the nanowires under electrical control or optical control so the active nanowires emit the radiation, the radiation decreasing the solubility of the negative resist; developing the resist level with the defective nanowires, leaving zones made less soluble and encircling the active nanowires; and removing the conductive layer above the defective nanowires. A process for fabricating one or more light-emitting diodes using the process is provided.
