A receiver has a receiving unit including a PLL, a mixer, and a filter, and demodulating unit including a frequency error detector for detecting a frequency error in a signal from a filter. The PLL includes a local oscillator for supplying a local oscillation signal to a mixer, a variable frequency divider for frequency-dividing the local oscillation signal based on a signal from the frequency error detector, and a phase comparator for comparing a signal from the variable frequency divider with a signal from a crystal oscillator. The PLL can reduce the frequency error of the local oscillation signal.

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.

An inexpensive and highly productive exposure device for directly scanning and exposing a photosensitive material sensitive to at least a UV region, based on digital data. As a motor controller moves an exposure head at a fixed speed in Y direction, image data is read one line of image data, each GLV element of a light modulator array is switched on/off by the read image data, and laser light from a high power light source of the exposure head is switched on/off. A UV-sensitive object to be exposed is exposed in X direction in a number of pixel units that substantially corresponds to the number of the GLV elements. The image data is scanned and exposed by one line in Y direction (main-scan). The motor controller moves a flat stage by one step in X direction (sub-scan). The object to be exposed is imagewise-exposed by repeating such scans.

A writing device is provided which, in simple processes, can write in two dimensions and three dimensions, and which can form highly accurate patterns. An exposure head, a conductive material discharging head, and an insulating material discharging head are disposed at one scanning stage. At the one scanning stage, a pattern can be formed on a printed board which is on the scanning stage. As a result, processes can be simplified, time between patternings can be shortened, and pattern formation can be made to be faster. Moreover, positional offset of the exposure head and the discharging heads with respect to the printed board does not arise. Thus, it is easy to increase a density of a pattern, and a highly accurate pattern is formed.

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.
