摘要： A laser annealer has a laser light source with at least one GaN-type semiconductor laser and is configured so as to form emission points that emit laser beams having a wavelength of 350 to 450 nm, and a scanning device for scanning an annealing surface with the laser beams. The laser annealer may have a spatial light modulator for modulating the laser beams, and in which pixel portions whose light modulating states change in accordance with control signals are arranged on a substrate. The invention is applied to a laser thin-film forming apparatus. The apparatus has a laser source that has at least one semiconductor laser and is configured so as to form emission points, and an optical system for focusing laser beams into a single beam in the width direction of a substrate.

摘要： An optical fiber of a bundled fiber light source is an optical fiber whose core diameter is uniform but whose emission end cladding diameter is smaller than an incidence end cladding diameter thereof, and a light emission region thereof is made smaller. An angle of luminous flux from this higher luminance bundled fiber light source, which passes through a lens system and is incident on a DMD, is smaller, i.e., an illumination NA is made smaller. Thus, an angle of flux which is incident on a surface that is to be exposed is smaller. That is, a minute image formation beam can be obtained without increasing the image formation NA, focal depth is lengthen.
