ABSTRACT:
Gated electron emitters are fabricated by processes in which charged particles are passed through a track layer (24, 48, or 144) to form charged-particle tracks (26.sub.1, 50.sub.1, or 146.sub.1). The track layer is etched along the tracks to create open spaces (28.sub.1, 52.sub.1, or 148.sub.1). Electron-emissive elements (30 or 142D) can then be formed at locations respectively centered on the open spaces after which a patterned gate layer (34B, 40B, or 158C) is provided. Alternatively, the open spaces in the track layer can be employed to etch corresponding apertures (54.sub.1) through an underlying non-insulating layer (46) which typically serves as the gate layer. An etch is performed through the apertures to form dielectric open spaces (56.sub.1, 96.sub.1, or 114.sub.1) in an insulating layer (24) that lies below the non-insulating layer. Electron-emissive elements (30B, 30/88D.sub.1, 98/102.sub.1, or 118.sub.1) can subsequently be provided, typically in the dielectric open spaces.
