Abstract:
A laser processing method includes a step of holding a film side of a workpiece which has been divided into chips and whose reverse side carries an adhesive film stuck thereto, a step of detecting widths of grooves in the workpiece at predetermined chip intervals and central coordinates of the widths of the grooves, a step of calculating laser beam irradiation lines based on the detected widths of the grooves and the detected central coordinates, a step of determining misalignment levels of the calculated laser beam irradiation lines according to misalignments of the grooves in widthwise directions thereof, and a step of processing the adhesive film with a laser beam by applying the laser beam to the adhesive film at bottoms of the grooves along the laser beam irradiation lines, thereby separating the adhesive film.

Claim (Index 3):
The laser processing method according to  claim 1 ,\n wherein a tape is stuck to a lower surface of the adhesive film on the reverse side of the workpiece; and the laser processing step includes a step of applying the laser beam to the tape along the grooves beyond an outer peripheral edge of the workpiece, thereby forming processing marks on the tape, the processing marks having lengths corresponding to the misalignment levels.
