  • Patent number: 7045441
    Abstract: A method for forming a, single-crystal silicon layer on a transparent substrate. A transparent substrate having an amorphous silicon layer formed thereon and a silicon wafer having a hydrogen ion layer formed therein are provided. The silicon wafer is then reversed and laminated onto the amorphous silicon layer so that a layer of single-crystal silicon is between the hydrogen ion layer and the amorphous silicon layer. The laminated silicon wafer and the amorphous silicon layer are then subjected to laser or infrared light to cause chemical bonding of the single crystal silicon layer and the amorphous silicon layer and inducing a hydro-cracking reaction thereby separating the silicon wafer is and the transparent substrate at the hydrogen ion layer, and leaving the single-crystal silicon layer on the transparent substrate.

  • Patent number: 6640403
    Abstract: A method for forming a dielectric-constant-enhanced capacitor is provided. A wafer in a reaction chamber is provided, wherein said wafer comprises a first conductive layer. Then, a first dielectric layer is formed above said first conductive layer to prevent said first conductive layer from growing silicon oxide and to diminish leakage current. Next a precursor is transmitted to a vaporizer. Then said precursor is transformed to a gas and said gas is transmitted to said reaction chamber. Next, a second dielectric layer is deposited above said first dielectric layer. Then a heat treatment is proceeded and a second conductive layer is formed on said second dielectric layer.

  • Publication number: 20030186074
    Abstract: This specification discloses a metal electrode that uses MoW (molybdenum-tungsten) alloy as its barrier layers and the method for making the same. Using MoW alloy as the barrier layer of a metal electrode can effectively solve the spiking and hillock problems occurred in aluminum electrodes. The MoW alloy barrier layer is thermally stable, preventing the resistance from rising due to the high-temperature manufacturing process. The metal electrode using the MoW alloy as the barrier layer can be prepared using the dry etching process. The resulting resistance is lower than other kinds of barrier layers. The MoW alloy barrier layer can be used in TFT metal electrodes for high-resolution and large-area displays.
