An image exposure device includes an exposure head for forming a desired pattern on a photosensitive material. The exposure head is equipped with a light source for emitting a great number of light beams, a spatial light modulator in which a great number of pixel portions are arranged for independently modulating the light beams emitted from the light source, a micro lens array in which a great number of micro lenses are arranged for individually converging the great number of light beams modulated by the pixel portions, and a total of two or more aperture arrays arranged in the stage before the micro lens array and/or the stage after the micro lens array.

An imaging head faces an imaging surface and is relatively moved along the scanning surface in a predetermined scanning direction. The imaging head includes an imaging element group and an alteration section. The imaging element group is structured by a plurality of imaging elements, which are arranged two-dimensionally in a plane substantially parallel to the imaging surface. The imaging element group generates a group of image pixels at the imaging surface in a two-dimensional arrangement which is inclined, as a whole, at a predetermined inclination angle with respect to the scanning direction. The alteration section alters a number of image pixels in a direction which is inclined from the scanning direction by the inclination angle, on the basis of a difference between the predetermined inclination angle of the imaging element group and an actual inclination angle of the image pixel group.

Imaging head, imaging device and imaging method

An optical wiring substrate fabrication method capable of simple formation, by maskless exposure, of an inclined face shape at an end portion of a core layer structuring an optical waveguide. Using an exposure apparatus, image exposure is carried out with a light beam which is modulated by a spatial modulation element in accordance with image information. A predetermined area of a photosensitive material (a photoresist), which is coated on the core layer which is a material of the optical wiring substrate, is exposed by a light beam (UV) and patterned to form an etching mask. A region corresponding to the inclined face, which is to be formed at the end portion of the core layer, is exposed and patterned by the light beam, exposure amounts of which are controlled in accordance with the inclined form of the inclined face, such that an end portion of the etching mask has an inclined face structure. When the core layer is worked by etching using this etching mask, working of the core layer at the end portion of the core layer progresses in proportion to film thickness of the etching mask, and the inclined face is formed.

Optical wiring substrate fabrication process and optical wiring substrate device

In an exposure head of the invention, plural first micro-focusing elements are arranged in a first microlens array so as to correspond to plural micromirrors in a DMD. An aperture array that includes plural apertures arranged so as to respectively correspond to the plural first micro-focusing elements is disposed. The apertures allow only main portions of Fraunhofer diffraction images to be transmitted therethrough. The main portions of the Fraunhofer diffraction images transmitted through the apertures are imaged on an exposure plane by second micro-focusing elements of a second microlens array. According to the exposure head of the invention, cross-talk light and scattered light can be effectively reduced, and beam diameters of beam spots projected on the exposure plane through the apertures can be adjusted to a required size.

Each micro lens of the micro lens array has an aspherical surface or a refractive index profile which corrects aberration due to distortion of the pixel portions or has a shape of lens aperture which does not permit light from a periphery of each of the pixel portions of the spatial light modulator element.

Image exposure system

A spatial light modulating method performs spatial light modulation of light produced by a light source. The method includes forming an image of a two-dimensional pattern of the light, which has been obtained from the spatial light modulation, on a photosensitive material, using an image-sided telecentric optical system. The method further includes altering an axial air separation, upstream of the photosensitive material, to thereby adjust a focusing point at the time of the formation of the image of the two-dimensional pattern of the light.

Projecting exposure method

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.
