    Abstract: A microminiature X-ray tube with a triode structure using a nano emitter is provided, which can increase a field emission region as much as possible by means of nano emitters fine-patterned in a cathode to not only increase an emission current per unit area as much as possible but secure high electrical characteristics, reliability, and structural stability by means of a cover and a bonding material. In addition, gate holes having a macro structure can be formed in the gate to promote electron beam focusing by means of the gate without using a separate focusing electrode and to prevent a leakage current from occurring on the gate. Further, an auxiliary electrode can be formed on a top or an inner surface of a cover applied for structural stability to further promote the electron beam focusing and to control the output amounts per individual X-ray tubes output according to current switching to be equal to each other.

    Abstract: Provided is a micro stage comprising: a body having a vertically perforated through-hole passing through a central portion thereof; a bobbin including a tip portion with an electron emission tip embedded in the center thereof, and passing through the through-hole of the body to be moved in the through-hole along a first axis perpendicular to a vertical direction; a first piezoelectric element disposed on the body and lengthened when a voltage is applied thereto to push the bobbin in one direction along the first axis; a second piezoelectric element disposed on the body and lengthened when a voltage is applied thereto to push the bobbin in the other direction along the first axis; and an upper cover that is coupled to an upper portion of the body and has a through-hole, through which the bobbin passes and communicates with the through-hole of the body, wherein the bobbin can be positioned as desired along the first axis by adjusting the voltages applied to the first piezoelectric element and the second piezoelectric element. Accordingly, the emission tip can be exactly and stably positioned using only the movable piezoelectric elements.

    Abstract: Provided is a method of manufacturing a carbon nano-tube (CNT) for a field emission device (FED) into which a nano-sized metal particle is added to thereby highly increase reliability of an electron emission source ("emitter"). The method of manufacturing a CNT emitter includes the steps of: (a) dispersing a CNT powder, an organic binder, a photosensitive material, a monomer, and a nano-sized metal particle in a solvent to thereby manufacture a CNT paste; (b) coating the CNT paste onto an electrode formed over a substrate; (c) exposing the CNT paste coated on the electrode to thereby perform fine-patterning; (d) plasticizing the finely patterned CNT paste; and (e) processing a surface of the CNT paste such that the surface of the plasticized CNT paste is activated. According to the above configuration, the CNT emitter can be finely patterned to several µm. Also, since a plurality of CNT emitter regions may be formed within a single pixel, uniformity of the electron emission can be improved. In addition, the nano-sized metal particle is added as a metal filler of the CNT paste, so that the metal can be melted at a low temperature where the CNT does not deteriorate. Furthermore, adhesion to a cathode electrode of the CNT is enhanced, so that the reliability of the CNT emitter can be improved.

    Abstract: Provided are methods of manufacturing carbon nanotube (CNT) paste, to which a nano-sized particle is added, and a CNT emitter with high reliability for a field emission display (FED). The method includes the steps of: (i) dispersing CNT powder in a solvent; (ii) adding an organic binder to the solution in which the CNT powder is dispersed; and (iii) performing a milling process to adjust viscosity of the dispersion solution to which the organic binder is added, wherein a nano-sized metal particle is added in step (i) or (iii). Accordingly, the nano-sized metal particle is added as a metal filler of the CNT paste, and thus a metal may be melted at a low temperature at which CNTs do not deteriorate. Thus, adhesion between the CNT paste and a cathode may be improved, and resistance between the cathode and the CNT or between CNTs may be reduced. Further, the CNT paste manufactured by the above method is employed in manufacturing the CNT emitter to thereby obtain uniform emission of electrons from the CNT emitter and increase electron emission sites, and thus the reliability of the CNT emitter may be further improved.
