LASER-PROCESSING METHOD |
摘要 |
<p>A laser processing method comprises the steps of generating a pulsed laser beam having a substantially circular shape; modifying the beam to a substantially rectangular shape; and scribing the surface of a workpiece with the rectangular beam to form grooves therein. The scribing step may include scanning the surface with the beam in a predetermined pattern, and aligning two parallel sides of the rectangular beam in parallel with the direction of the scanning. The beam may be made square, or may have unequal sides with the longer sides preferably arranged in parallel with the scanning direction.</p> |
