Abstract

See full text

Methods and apparatuses for reducing taper of a laser scribe in a substrate are described. One method includes aiming a laser beam at a surface of the substrate in a first direction perpendicular to a first cutting direction of the beam and aiming it at the surface in a second direction perpendicular to the first cutting direction. In each position, the laser beam is tilted at a beam tilt angle with respect to a line perpendicular to the surface. A single scribe line is formed in the surface by applying the laser beam to the surface while aiming the laser beam in the first direction and cutting in the first cutting direction and applying the laser beam to the surface while aiming the laser beam in the second direction and cutting in one of the first cutting direction and a second cutting direction opposite the first cutting direction.
