20090278060 | PHOTOIRRADIATION APPARATUS, CRYSTALLIZATION APPARATUS, CRYSTALLIZATION METHOD, AND DEVICE - A photoirradiation apparatus includes an optical modulation element which phase-modulates light, an illumination system to illuminate the optical modulation element, and an imaging optical system which applies the phase-modulated light to a non-single-crystal semiconductor film to form a predetermined light intensity distribution with a strip-like repetitive region having long sides adjacent to each other. The light intensity distribution has a distribution which is downwards convex along a center line in a short side direction and a center line in a long side direction of the repetitive region. The light intensity distribution includes isointensity lines each bent to form a projection from a center of the repetitive region outward in the long side direction. A radius of curvature of an end of at least one isointensity line is not more than 0.3 μm. A pitch of the repetitive region in the short side direction is not more than 2 μm. | 11-12-2009 |
