Abstract

The whole surface of a polycrystalline or amorphous semiconductor film deposited so as to continuously cover the surface of a single-crystal substrate and an insulating film is irradiated with a laser beam or electron beam, thereby to selectively melt only those parts of the polycrystalline or amorphous semiconductor film which overlie the insulating film. Thus, a single-crystal semiconductor film is formed only the insular insulating film formed on the single-crystal substrate.
