    Abstract: A withdrawn electrode is formed on a silicon substrate with intervention of upper and lower silicon oxide films each having circular openings corresponding to regions in which cathodes are to be formed. Tower-shaped cathodes are formed in the respective openings of the upper and lower silicon oxide films and of the withdrawn electrode. Each of the cathodes has a sharply tapered tip portion having a radius of 2 nm or less, which has been formed by crystal anisotropic etching and thermal oxidation process for silicon. The region of the silicon substrate exposed in the openings of the upper and lower silicon oxide films and the cathode have their surfaces coated with a thin surface coating film made of a material having a low work function.

    Abstract: A field emitter element comprising a bottom layer of material shaping the overall emitter element, and a top layer of low work function material or otherwise of high electron emissivity characteristic. The low work function top layer preferably is shaped to a sharp point. The bottom layer may be formed of a material such as tantalum, molybdenum, gold, or silicon (or alloys thereof), and the top layer may be formed of a material such as Cr.sub.3 Si, Cr.sub.3 Si.sub.2, CrSI.sub.2, Nb.sub.3 Si.sub.2, Nb, Cr.sub.2 O.sub.3 or SiC. In a specific aspect, at least one of the first and second emitter materials is chromium oxide (Cr.sub.2 O.sub.3). In another variant, the first emitter material is an insulator of leaky dielectric, e.g., SiO with a 10-60% Cr by weight based on the weight of SiO, and the second emitter material is SiO+50-90% Cr by weight, based on the weight of SiO.

    Abstract: A matrix addressable flat panel display includes a flat cathode operable for emitting electrons to an anode when an electric field is produced across the surface of the flat cathode by two electrodes placed on each side of the flat cathode. The flat cathode may consist of a cermet or amorphic diamond or some other combination of a conducting material and an insulating material such as a low effective work function material. The electric field produced causes electrons to hop on the surface of the cathode at the conducting-insulating interfaces. An electric field produced between the anode and the cathode causes these electrons to bombard a phosphor layer on the anode.

    Abstract: In a field emission type cathode structure for a CRT, a grid electrode has an opening at a position corresponding to a position of a bonding wire for connecting a gate electrode to a lead connected to a power supply for a gate voltage. A bonding tool moves vertically through the opening of the grid electrode to bond the bonding wire on the gate electrode and the lead.

    Abstract: A field emission element including a gate and an emitter and capable of preventing any of the element oxide layer from being formed on a tip of the emitter to prevent a decrease in emission current, unstable operation and an increase in noise. The gate has a surface formed of a material of oxygen bonding strength higher than that of a material for at least a tip surface of the emitter, so that oxygen atoms and molecules containing oxygen entering the gate may be captured by adsorption on the gate to prevent formation of any oxide layer on the emitter. When a portion of the emitter other than the tip surface is formed of a material of oxygen bonding strength higher than that of the material for the tip surface, formation of any oxide layer on the tip surface of the emitter is minimized.
