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