A manufacturing method of a semiconductor thin film decreases the number of and controls the direction of crystal grain boundaries. A first beam irradiated onto amorphous silicon produces a radial temperature gradient centered on a tip of a concave. This forms a crystal grain in the concave tip, which grows in both the beam width and length direction. After the second beam and on, growth is repeated using the crystal grain formed in the tip of the concave as the seed. This forms a band-form crystal grain with a wider than that of the conventional narrow-line beam, with the tip of the concave being the start point. Further, by setting the periphery of the concave pattern to be equal or less than the crystal grain diameter in the direction vertical to the beam scanning direction, it is possible to form the band-form crystal grain being lined continuously.
