Abstract
PURPOSE:To manufacture a homogenous polycrystalline film in a large area with less film roughness by forming an intensity distribution of a laser beam uniformly in a longitudinal direction and in a trapezoidal or similar shape in a lateral direction, and irradiating a laser while scanning on a thin semiconductor film. CONSTITUTION:A hydrogenated amorphous silicon film 2 formed on a glass substrate 1 is polycrystallized by irradiating it with an excimer laser beam 4. In this case, the beam 4 from a laser device 7 is uniform in a longitudinal direction and has a trapezoidal intensity profile in a lateral direction, and it is laser-annealed by scanning it with the beam in this direction. As a result, it is annealed gradually in higher intensity at the same ground point, thereby obtaining a homogenous crystalline film 3 having no surface roughness.
