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 1):
A laser processing method for applying a laser beam to an adhesive film applied to a reverse side of a workpiece, which has been divided into individual chips along a plurality of intersecting streets on a face side of the workpiece, with grooves formed in the workpiece along the streets and the adhesive film disposed at the bottoms of the grooves, comprising:\n a holding step of holding an adhesive film side of the workpiece on a holding table; a groove width detecting step of detecting widths of the grooves in the workpiece held in the holding step at predetermined chip intervals and detecting central coordinates of the widths of the grooves; a laser beam irradiation line calculating step of calculating laser beam irradiation lines along which the laser beam is to be applied to the adhesive film, based on the widths of the grooves and the central coordinates thereof detected in the groove width detecting step; a level determining step of determining misalignment levels of the laser beam irradiation lines calculated in the laser beam irradiation line calculating step according to misalignments of the grooves in widthwise directions thereof; and a laser processing step of processing the adhesive film with the laser beam by applying the laser beam to the adhesive film at the bottoms of the grooves along the laser beam irradiation lines calculated in the laser beam irradiation line calculating step, thereby separating the adhesive film; wherein the laser processing step includes a step of processing the adhesive film with the laser beam under processing conditions corresponding to the misalignment levels determined in the level determining step.
