Abstract

A method for forming a semiconductor thin film comprises crystallizing an amorphous silicon thin film by a first thermal treatment at 700.degree. C. or lower for ten hours or longer and carrying out a second thermal treatment at 1200.degree. C. or higher in which a lamp light is radiated to the crystallized thin film.
