摘要： A knife edge is disposed at a height corresponding to a section on which a sectional image (light intensity distribution) is picked up in such a manner as to intercept a part of the section of the laser light. The knife edge is irradiated with the laser light, and the sectional image of the laser light is enlarged with an image forming optics, and is picked up by a CCD. While picking up the sectional image in this manner, focusing of the image forming optics is performed. Next, the knife edge is retracted from the optical path of the laser light, the laser light is allowed to enter the CCD via the image forming optics, and the sectional image of the laser light is picked up.

摘要： Exact alignment of a recrystallized region, which is to be formed in an amorphous or polycrystalline film, is facilitated. An alignment mark is formed, which is usable in a step of forming an electronic device, such as a thin-film transistor, in the recrystallized region. In addition, in a step of obtaining a large-grain-sized crystal-phase semiconductor from a semiconductor film, a mark structure that is usable as an alignment mark in a subsequent step is formed on the semiconductor film in the same exposure step. Thus, the invention includes a light intensity modulation structure that modulates light and forms a light intensity distribution for crystallization, and a mark forming structure that modulates light and forms a light intensity distribution including a pattern with a predetermined shape, and also forms a mark indicative of a predetermined position on a crystallized region.
