ABSTRACT:
A field emission device and method of forming same, comprising a substrate on which at least one conical electrode is provided, which substrate, with the exception of the proximity of the tip of the electrode, is covered with a layer of a dielectric material on which a conductive layer is present at least locally, in which in order to form an integrated accelerating electrode the conductive layer extends in the direction of the punctiform tip of the electrode to beyond the dielectric layer and shows an aperture above the tip so that the conductive layer forms a cap-shaped accelerating electrode surrounding the conical electrode.
