Patent ID: 8436355

Claim:
A method of manufacturing a thin-film transistor, said method comprising: forming a gate electrode on a substrate, forming an insulation layer so as to cover the gate electrode, forming a semiconductor layer on the insulation layer, and forming a crystallization-inducing metal layer on the semiconductor layer; removing at least a part of the crystallization-inducing metal layer, the part being over a channel region of the semiconductor layer; forming source and drain electrodes at positions on the crystallization-inducing metal layer which are over source and drain regions respectively, the source and drain regions being located at respectively opposite sides with respect to the channel region of the semiconductor layer; and heating the crystallization-inducing metal layer to form a silicide layer of a crystallization-inducing metal, wherein, in said forming of an insulation layer, a semiconductor layer, and a crystallization-inducing metal layer, outer circumferences of the insulation layer, the semiconductor layer, and the crystallization-inducing metal layer are not located inwards of an outer circumference of the gate electrode and are formed to extend outside the outer circumference of the gate electrode, so as to form curved planes or slanted planes, each of which faces the channel region of the semiconductor layer, in the semiconductor layer and the crystallization-inducing metal layer outside the outer circumference of the gate electrode, and in said heating, the crystallization-inducing metal layer is heated in a state in which the curved planes or the slanted planes are formed in the semiconductor layer and the crystallization-inducing metal layer.
