Abstract:
The invention relates to a method of processing a substrate. The substrate has on a first surface a device area with a plurality of devices partitioned by a plurality of division lines. A pulsed laser beam is applied to the substrate at least in a plurality of positions along each of the division lines, with a focal point located at a distance from the first surface in the direction from the first surface towards a second, opposite surface, so as to form a plurality of modified regions in the substrate along each of the division lines. The second surface of the substrate is then ground to adjust the substrate thickness. After forming modified regions and/or hole regions in the substrate, a plasma can be applied to the substrate so as to form a plurality of grooves extending along the division lines.

Claim (Index 12):
A method of processing a substrate, having a first surface and a second surface opposite the first surface, wherein\n the substrate has on the first surface a device area with a plurality of devices partitioned by a plurality of division lines; and the method comprises: applying a pulsed laser beam to the substrate from the side of the first surface or the side of the second surface, wherein the pulsed laser beam is applied to the substrate at least in a plurality of positions along each of the division lines so as to form a plurality of modified regions and/or a plurality of hole regions in the substrate along each of the division lines; and after forming the modified regions and/or the hole regions in the substrate, applying a plasma to the substrate so as to form a plurality of grooves in the substrate extending along the division lines where the plurality of modified regions and/or the plurality of hole regions has been formed.
