The device includes: a stage mounting the substrate; a laser oscillator for generating a laser beam; a projection lens for focusing and guiding the laser beam onto the thin film; a reflector for reflecting the laser beam guided onto the thin film; a controller for controlling a position of the reflector; and an absorber for absorbing the laser beam reflected by the reflector.
Abstract:
A mask for forming polysilicon has a first slit region where a plurality of horizontal slit patterns are arranged in the vertical direction while bearing the same width, a second slit region where a plurality of horizontal slit patterns are arranged in the vertical direction while bearing the same width, a third slit region where a plurality of horizontal slit patterns are arranged in the vertical direction while bearing the same width, and a fourth slit region where a plurality of horizontal slit patterns are arranged in the vertical direction while bearing the same width. The slit patterns arranged at the first to fourth slit regions are sequentially enlarged in width in the horizontal direction in multiple proportion to the width d of the slit pattern at the first slit region. The centers of the slit patterns arranged at the first to fourth slit regions in the horizontal direction are placed at the same line. The slit patterns arranged at the respective slit regions in the vertical direction are spaced from each other with a distance of 8*d. Alternatively, the first to fourth slit regions may be arranged in reverse order, or in the vertical direction.

Disclosed is an illuminating device using light emitting elements. The illuminating device includes a plurality of focusing lens sets (2) including light emitting elements and a lens assembly for gathering light such that the light radiated from the light emitting elements is directed to a single focusing point within a predetermined incident angle, a light transfer unit (3) spaced apart from the focusing lens sets (2) by a predetermined distance and including an optical fiber or an optical waveguide having a light incident surface formed at the focusing point and a light emitting surface formed in opposition to the light incident surface, and a light radiating unit (4) connected to the light emitting surface of the light transfer unit (3) in order to radiate the light generated from the light emitting surface toward a predetermined area. The light emitting elements, such as laser diodes or LEDs, are used as light sources. Light generated from the light emitting element is focused onto the light incident surface of the optical fiber or the optical waveguide spaced apart from the light emitting element by a predetermine distance, so that the light emits through the light emitting surface by passing through the optical fiber or the optical waveguide, thereby illuminating a desired place. The illuminating device effectively illuminates a specific area located within a short distance or a long distance (more than 1 Km) from the illuminating device. If the light radiating unit (4) is fabricated in the form of a projection lens set equipped with a reverse-zoom lens, the illuminating device maximizes the light efficiency in cooperation with an external device, such as a camera using a zoom lens.
