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.

摘要： Disclosed are apparatus for forming a semiconductor film having an excellent crystallinity from a non-single crystal semiconducting layer formed on a base layer made of an insulating material. The apparatus includes a light source, a homogenizer for homogenizing an intensity distribution of the emitted light, an amplitude-modulation means for performing the amplitude-modulation such that the amplitude of the light, of which the intensity distribution is homogenized, is increased in the direction of the relative motion of the light to the base layer, an optional light projection optical system for projecting the amplitude-modulated light onto the surface of the non-single crystal semiconductor such that a predetermined irradiation energy can be obtained, a phase shifter for providing a low temperature point in the surface irradiated by the light, and a substrate stage to move the light relative to the substrate thereby enabling scanning in the X and Y axis.
