Abstract:
A method for fabricating a semiconductor device, comprising the steps of:(a) forming an amorphous semiconductor film on a substrate having an insulating surface;(b) forming a predetermined layer containing a catalyst element for accelerating crystallization of the amorphous semiconductor film, on at least a portion of a surface of the amorphous semiconductor film; and(c) conducting a heat treatment so as to introduce the catalyst element into the amorphous semiconductor film in a diffused manner and to polycrystallize at least a portion of the amorphous semiconductor film,wherein the predetermined layer is a photosensitive material layer containing the catalyst element formed in an island pattern on the surface of the amorphous semiconductor film, and the catalyst element is selectively introduced from the island of the photosensitive material layer in the step (c).
