    • PURPOSE: A crystallizing apparatus is provided to form a crystallized semiconductor layer of a large diameter by adjusting the light intensity distribution acquired by a phase shifter to have a relatively arranged and continued V shape and by embodying a crystal growth of a sufficient lateral length from a crystal nucleus. CONSTITUTION: An illumination optical system(2) is prepared. A phase shifter(1) optically modulates the optical beam from the illumination optical system into a predetermined light intensity distribution. The optically modulated light beam is irradiated to a polycrystalline semiconductor layer or an amorphous semiconductor layer(4) to form a crystallized semiconductor layer. The illumination optical system irradiates a light beam whose cross section is not circular. The light beam from the illumination optical system and the phase shifter are optically and relatively rotated with respect to the optical axis of the light beam by a rotation unit(3).
