A method for manufacturing a semiconductor device that can prevent short-circuiting between gate electrodes and increases in the leakage current of a capacitive insulating film caused by the bottom electrode of the capacitor is provided. The method for manufacturing a semiconductor device according to the present invention comprises a first step for forming an amorphous silicon film on a semiconductor substrate; a second step for forming a stopper film on a surface of the amorphous silicon film to prevent migration of the surface of the amorphous silicon film; and a third step for removing the stopper film from the surface of the amorphous silicon film.
