Abstract
This laser processing method irradiates a substratewith laser light L while locating a light-converging point P within the substrate, so as to form a quality modified regionto become a starting point region for cutting within the substratealong a line to cut. Here, the laser light L is oscillated pulsewise along a desirable part RP in the line to cut, and continuously in a predetermined part RC in the line to cut. Consequently, the quality modified regionis formed within the substratealong the desirable part RP in the line to cut, whereas no quality modified regionis formed within the substratealong the predetermined part RC in the line to cut
