The second laser beam may be irradiated to the thin-film in such a way as to overlap with the first irradiated region, where an alignment mark is formed by using an optical constant difference between the first and second irradiated regions or between the second irradiated region and the non-irradiated region. Preferably, the thin-film is made of a-Si or poly-Si.
