Abstract:
A laser processing method for a wafer that is segmented by plural planned dividing lines set on a surface in a lattice manner uses a laser processing apparatus including a laser beam irradiation unit that irradiates, through a collecting lens, the wafer held by a chuck table, with plural laser beams formed by being oscillated by a laser beam oscillator and being split by a laser beam splitting unit. The method includes a processed groove forming step of irradiating the wafer with the plural laser beams along the planned dividing lines and forming a processed groove along the planned dividing lines. The plural laser beams split by the laser beam splitting unit are arranged in a line manner along a direction that is non-parallel to an extension direction of the planned dividing line irradiated with the plural laser beams.

Claim (Index 2):
The laser processing method of a wafer according to  claim 1 , wherein\n in the processed groove forming step, the wafer is irradiated with the plurality of laser beams along each of the plurality of planned dividing lines two or more times and the wafer is divided by the processed grooves.
