Abstract:
A substrate dividing method which can thin and divide a substrate while preventing chipping and cracking from occurring. This substrate dividing method comprises the steps of irradiating a semiconductor substrate  1  having a front face  3  formed with functional devices  19  with laser light while positioning a light-converging point within the substrate, so as to form a modified region including a molten processed region due to multiphoton absorption within the semiconductor substrate  1 , and causing the modified region including the molten processed region to form a starting point region for cutting; and grinding a rear face  21  of the semiconductor substrate  1  after the step of forming the starting point region for cutting such that the semiconductor substrate  1  attains a predetermined thickness.

Claim (Index 11):
The method of manufacturing a semiconductor chip according to  claim 7 , wherein the method comprises a step of attaching a protective film on the front face of the semiconductor wafer before forming the plurality of a modified regions.
