ABSTRACT:
A method of forming thin-film semiconductor device is provided in which an island region of an isolated single-crystal thin-film is formed on an entire surface or within a specific region of an insulating film by utilizing cohesion phenomena due to the surface tension of a melted semiconductor, wherein more than one active region of a thin-film transistor is formed in the island region.
