LASER-PROCESSING DEVICE

摘要

The present invention relates to a laser-processing device. More specifically, the present invention relates to a laser-processing device which is used during the work of laser lift-off in which a thin film is separated from a substrate. The laser-processing device according to the present invention comprises: a laser-beam light source for emitting a laser beam; an optical system for forming the laser beam emitted from the laser-beam light source, and for processing the energy distribution; a stage for irradiating the laser beam which has been processed by means of the optical system, and for receiving a processing object which is to be processed by means of the irradiated laser beam; and a suction unit which is placed on the propagation pathway of the laser beam in such a way as to allow the passage of the laser beam processed by means of the optical system, and which has the task of sucking in scattered material produced during the processing of the processing object.
