  • Publication number: 20130008784
    Abstract: Provided is a CoCrPt-based alloy sputtering target containing cobalt (Co), chromium (Cr), platinum (Pt), cobalt oxide and non-magnetic oxide composition, wherein the lengths of ceramic phases of Cr2O3 and Co(Cr)—X—O formed in the sputtering targets are respectively less than 3 ?m (“X” represents the metal element of the non-magnetic oxide). The sputtering target is obtained via controlling suitable composition proportion of the prealloy powder with Cr and the sintering factor to decrease the size of ceramic phases of Cr2O3 and Co(Cr)—X—O. Sputtering targets made by the methods of the present invention decrease the arcing effects and unnecessary formation of particles upon sputtering in addition to making the components of the sputtering targets distribute more uniformly therein.

  • Publication number: 20120114976
    Abstract: The present invention provides a sputtering target essentially consisting of cobalt-platinum-copper oxide-oxide (CoPt—CuO-oxide), cobalt-chrome-platinum-copper oxide-oxide (CoCrPt—CuO-oxide), or cobalt-chrome-platinum-boron-copper oxide-oxide (CoCrPtB—CuO-oxide) with addition of CuO. The sputtering target is applied to a recording material of a magnetic recording medium. The thickness of the oxide grain boundary in the sputtering target is reduced, resulting from the decreased amount of oxide in the sputtering target, to allow a sputtering process utilizing the same to become more stable. Further, the volume of the magnetic grains per unit area is increased, whereby a better thermal stability and a high recording density are acquired.

  • Publication number: 20120114975
    Abstract: Disclosed is a sputtering target and its application to the recording material of hard disks wherein the sputtering target comprises cobalt-platinum (CoPt), cobalt-chrome-platinum (CoCrPt) or cobalt-chrome-platinum-boron (CoCrPtB) and a combination of oxides. A recording material is formed by the sputtering target through the sputtering process as a high areal recording density hard disk, which essentially has silica oxide (SiO2) and Cr2O3, wherein the amount of silica oxide (SiO2) ranges from 4 to 8 atomic % and the amount of chromium oxide (Cr2O3) ranges from 0.8 atomic % to 5 atomic %. The present invention is characterized by Cr2O3 as an oxygen supplier during sputtering process to donate oxygen to the oxygen defects. The sputtering target containing the combination of oxides is used to form a recording material applied as a recording layer of magnetic recording medium of hard disks, resulting in enhancement of the areal recording density of medium storage.

  • Publication number: 20060131568
    Abstract: A device having an organic transistor device integrated with an organic light-emitting diode's heterojunctions. This device at least comprises: a transparent substrate, an organic transistor and an organic light-emitting diode. The organic transistor at least includes an organic semiconductor layer, one of the organic semiconductor layers serves as the organic active layer of the organic light-emitting diode, and the organic active layer and the other organic semiconductor layers form heterojunctions. The present invention uses the organic semiconductor layer to simultaneously form the organic active layer of the organic transistor, so that the organic light-emitting diode and the organic transistor can be easily integrated together so as to solve the problem of the poor luminance efficiency of a conventional integrated organic transistor and organic light-emitting diode and the problem of its high manufacturing cost.

  • Patent number: 6672926
    Abstract: A method of fabricating an emitter of a field emission display. A mixture of metal and silver paste with glass material is screen printed on a substrate as a silver electrode. The metal is selected from a hard solder alloy such as Al/Si alloy containing tin, zinc, aluminum or other low melting point metal. Alternatively, the metal and the silver paste with the glass material are separately screen printed on the substrate. The metal is selected from tin, zinc, aluminum, or an alloy with a low melting point such as aluminum/silicon alloy. A carbon nano-tube layer is formed on the silver electrode by coating the carbon nano-tube material with the electric arc. Alternately a catalyst layer can be formed on the silver electrode prior to the formation of the carbon nano-tube layer. A metal layer such as nickel and copper is formed on the carbon nano-tube layer to prevent the carbon nano-tube layer from absorbing gas.
