  • Patent number: 7105443
    Abstract: A method for fabricating epitaxial cobalt disilicide layers uses a cobalt-nitride thin film. Epitaxial cobalt disilicide (CoSi2) layers are fabricated using a cobalt-nitride thin film in a salicide process, wherein a silicide is formed on source/drain regions and a polysilicon gate electrode of a nanoscale MOS transistor. Epitaxial CoSi2 layers can be fabricated on source/drain regions and a gate electrode of a silicon substrate using a cobalt-nitride thin film, without the formation of an interlayer between a cobalt layer and the silicon substrate.

  • Publication number: 20060017368
    Abstract: A transparent light-emitting conductive layer includes a Transparent Conductive Oxide (TCO) and a dopant. An electron emission device having the transparent light-emitting conductive layer includes: a front substrate; a first electrode arranged on the front surface, the first electrode having a transparent light-emitting conductive layer including a Transparent Conductive Oxide (TCO) and a dopant; a fluorescent layer arranged on the first electrode; a rear substrate spaced apart from and facing the front substrate; an electron emission region arranged on the rear substrate; and a second electrode adapted to control electron emission in the electron emission region. The electron emission device can be used as an electron emission display device or a back-light unit.

  • Patent number: 6528361
    Abstract: The present invention relates to a process for preparing a polycrystalline silicon thin film comprising a step of microwave annealing and crystallization of an amorphous thin film of silicon semiconductor, silicon semiconductor added with impurities, IV family semiconductor comprising Si alloy such as Si1−xGex, III-V family and II-VI family semiconductor. The process for preparing polycrystalline silicon thin film of the present invention comprises the steps of: immersing a washed substrate into a deposition equipment and heating the substrate; depositing an amorphous or microcrystalline silicon thin film on the substrate; and, annealing the deposited thin film employing microwave for crystallization.
