Patent ID: 8389894

Claim:
A laser processing apparatus for processing a multitude of portions to be processed in an area to be processed in a subject to be processed, comprising a laser device; a focusing or imaging means for simultaneously outputting multiple laser beams using a laser beam emitted from the laser device; and a position adjusting mechanism configured to adjust a position of the subject to be processed, wherein: the laser devise emits the laser beam in a beam area that comprises the area to be processed and an area outside the area to be processed; the position adjusting mechanism is configured to move a unit from outside to inside of the beam area and passes the unit through the beam area, wherein the unit comprises the subject to be processed and said unit also comprises the focusing or imaging means, the subject and the focusing or imaging means being moved in a manner in a fixed relation to each other so that cumulative laser beam irradiation time during the processing of each of the multitude of portions to be processed is equalized; and the laser processing apparatus processes the subject to be processed while the position adjusting mechanism relatively moves the subject to be processed and the focusing or imaging means in relation to the laser beam.
