First Claim
1. A laser processing device, comprising:
- a laser light source for radiating laser light;
a laser-processing stage having an installation surface on which a plurality of objects are arranged;
a plurality of reflecting members arranged at fixed intervals along a predetermined direction on the installation surface of the laser-processing stage such that the plurality of objects are separated from each other in a laser scanning direction, the plurality of reflecting members respectively having reflecting surfaces inclined relative to the installation surface; and
radiation optics for scanning with the laser light emitted from the laser light source over the objects arranged on the laser-processing stage and over irradiated locations in the periphery thereof while radiating the laser light from a direction perpendicular to the installation surface,wherein each of the plurality of reflecting members adjacent to objects positioned at both sides thereof is positioned on the installation surface of the laser-processing stage such that the reflecting surfaces thereof reflect the laser light toward the adjacent objects positioned at both sides thereof when the laser light is irradiated from the direction perpendicular to the installation surface, andwherein laser light that has reached one of the reflecting members is reflected by the reflecting surface of the reflecting member reached by the laser light, and one lateral surface of the object among the plurality of objects that is adjacent to the reflecting member reached by the laser light is irradiated.

Abstract
The present invention relates to a laser processing method and the like provided with a structure for enabling realization of both preferable processing of locations not easily reached by laser light and effective inhibition of damage caused to locations easily reached by laser light during laser processing. Radiation optics scan locations irradiated with laser light from a laser light source while radiating laser light onto a plurality of objects arranged on a stage and the periphery thereof from a direction perpendicular to the stage. On the stage reflecting members are respectively arranged adjacent to the plurality of objects. The reflecting members reflect laser light radiated from the radiation optics towards lateral surfaces of the objects. Since laser light reflected by the reflecting members is radiated onto the lateral surfaces of the objects, laser light also reaches the lateral surfaces of the objects not easily reached by laser light without having to increase the intensity of the laser light.
