  • Patent number: 8735233
    Abstract: A crystalline silicon thin film is formed by irradiating a silicon thin film with a laser beam. The laser beam is a continuous wave laser beam. An intensity distribution of the laser beam in a first region about a center of the intensity distribution is symmetric on an anterior side and a posterior side of the center. The intensity distribution in a second region about the center is asymmetric on the anterior side and the posterior side. The first region is from the maximum intensity of the laser beam at the center to an intensity half of the maximum intensity. The second region is at most equal to the half of the maximum intensity of the laser beam. In the second region, an integral intensity value on the posterior side is larger than on the anterior side.
