ABSTRACT:
A footprint (an area on a plane necessary for processing) of a laser irradiation apparatus for moving a stage supporting thereon a substrate in X and Y direction becomes unavoidably large when the substrate becomes greater in size, and the apparatus becomes very great as a whole. In a laser irradiation apparatus of the invention, a galvanomirror or a polygon mirror irradiates and scans a laser beam to and on a semiconductor film and always keeps an angle θ of incidence of the laser beam to the semiconductor film at a certain angle.
