  • Publication number: 20090155988
    Abstract: A low temperature poly-silicon thin film element, method of making poly-silicon thin film by direct deposition at low temperature, and the inductively-coupled plasma chemical vapor deposition equipment utilized, wherein the poly-silicon material is induced to crystallize into a poly-silicon thin film at low temperature by means of high density plasma and substrate bias voltage. Furthermore, the atom structure of the poly-silicon thin film is aligned in regular arrangement by making use of the induction layer having optimal orientation and lattice constant close to that of the silicon, thus raising the crystallization quality of the poly-silicon thin film and reducing the thickness of the incubation layer.

  • Patent number: 7361566
    Abstract: A method of forming poly-silicon thin film transistors is described. An amorphous silicon thin film transistor is formed on a substrate, and then the Infrared (IR) heating process is used. A gate metal and source/drain metal are heated rapidly, and conduct heat energy to an amorphous silicon layer. Next, crystallization occurs in the amorphous silicon layer to form poly-silicon. Therefore a poly-silicon thin film transistor is produced.

  • 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.
