Abstract: The generation of a projecting intensity distribution in an irradiation laser beam used for forming a polycrystalline semiconductor film is prevented by irradiating the laser beam onto an amorphous semiconductor film to crystallize it while it is being scanned. A dog-ear removing filter for eliminating diffracted light that occurs at boundaries of lenses and acts as a cause of development of dog-ears in the light intensity distribution is disposed in an optical system to cause the light intensity distribution in the irradiation laser beam to be uniform. As a result, by removing the dog ear distributions, the necessity for making the light intensity distribution of the laser beam blur is eliminated, and, consequently, a distribution of high energy efficiency can be maintained and the throughput is improved.

Abstract: A surface roughness of a polycrystalline semiconductor film to be formed by a laser annealing method is reduced. A transmittance distribution filter is disposed at the optical system of a laser annealing apparatus. The transmittance distribution filter controls an irradiation light intensity distribution along a scanning direction of a substrate formed with an amorphous silicon semiconductor thin film to have a distribution having an energy part equal to or higher than a fine crystal threshold on a high energy light intensity side and an energy part for melting and combining only a surface layer. This transmittance distribution filter is applied to an excimer laser annealing method, a phase shift stripe method or an SLS method respectively using a general line beam to thereby reduce the height of protrusions on a polycrystalline surface.

Abstract: The average film thickness of an amorphous silicon film formed on a substrate is measured. Then, the amorphous silicon film is irradiated with a laser beam to form a polysilicon film. The grain size distribution of the polysilicon film is measured. An optimum value of energy density of laser beam irradiation is calculated on the basis of grain size values measured at two points A and B of the polysilicon film. Then, the average film thickness of a next amorphous silicon film is measured. A value of energy density of laser beam irradiation is calculated on the basis of the average film thickness of the next amorphous silicon film and the average film thickness of the previous amorphous silicon film. The value of energy density is fed back to a laser beam irradiation system.
