Method for manufacturing a semiconductor thin film |
摘要 |
A little amount of nickel is introduced into an amorphous silicon film formed on a glass substrate to crystallize the amorphous silicon film by heating. In this situation, nickel elements remain in a crystallized silicon film. An amorphous silicon film is formed on the surface of the crystallized silicon film and then subjected to a heat treatment. With this heat treatment, the nickel elements are diffused in the amorphous silicon film, thereby being capable of lowering the concentration of nickel in the crystallized silicon film.
