    摘要: In producing a thin film transistor, after an amorphous silicon film is formed on a substrate, a nickel silicide layer is formed by spin coating with a solution (nickel acetate solution) containing nickel as the metal element which accelerates (promotes) the crystallization of silicon and by heat treating. The nickel silicide layer is selectively patterned to form island-like nickel silicide layer. The amorphous silicon film is patterned. A laser light is irradiated while moving the laser, so that crystal growth occurs from the region in which the nickel silicide layer is formed and a region equivalent to a single crystal (a monodomain region) is obtained.

    摘要: In a producing a thin film transistor, a solution containing a metal element for promoting crystallization of silicon is added in contact with an amorphous silicon film, and then a silicide layer is formed by heating process. Further, after a region as crystal growth nucleus-is formed by patterning the silicide layer, laser light is irradiated during heating process. As a result, crystal-growth is performed from the region as crystal growth nucleus in the amorphous silicon film, thereby to form monodomain regions corresponding to a single crystal. Also, before the solution is added, the amorphous silicon film may be subjected to plasma treatment 30.

    摘要: Thin-film transistors (TFTs) having characteristics comparable to those of a single-crystal silicon wafer are provided. A buffer film made from silicon oxide is formed on a first amorphous silicon film. A nickel acetate solution containing a metal element such as nickel for promoting crystallization of silicon is applied to the first amorphous silicon film. The laminate is heat-treated to form a nickel silicide layer. The nickel silicide layer is then patterned. A second amorphous silicon film is formed and heat-treated to grow crystals. Thus, monodomain regions which can be regarded as single crystals are formed. Active layers of TFTs are formed from these monodomain regions.
