To provide a laser irradiation apparatus and a laser irradiation method in which a region formed with microcrystals in a region irradiated with laser beams is decreased by disposing a slit in an optical system using a deflector, and laser processing can be favorably conducted to a semiconductor film. Further to provide a semiconductor manufacturing apparatus using the above-described laser irradiation apparatus and the laser irradiation method. In the optical system, an f-θ lens having an image space telecentric characteristic or a slit the shape of which is changed in accordance with the incidence angle of a laser beam, is used. The slit is disposed between the f-θ lens and an irradiation surface, and an image at a slit opening portion is projected onto the irradiation surface by a projection lens. By the above-described structure, laser irradiation can be uniformly conducted to a whole region scanned with laser beams.

A near-field light generator plate 36 of the present invention is arranged to face a medium 10, and one portion 36b and other portion 36a in a medium-facing surface S thereof are made of their respective electroconductive materials different from each other. Since the one portion and the other portion in the medium-facing surface are made of the electroconductive materials different from each other, this medium-facing surface is formed by a surface removing step such as polishing or etching from the medium-facing surface side so that a difference between heights of the one portion and the other portion is readily made based on the difference of the materials.
