Device for irradiating a laser beam |
摘要 |
A device for irradiating a laser beam onto an amorphous silicon thin film formed on a substrate. 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. |
