Filed: 2020-01-20
Abstract: An objective of the present invention is to easily check the effect of a laser beam irradiation on a surface of a workpiece. A modified layer (T) is formed by forming two line-shaped processing marks (M1, M2) on a metal foil (5) of a wafer for verification and irradiating a laser beam to a reference position in the middle. Although the modified layer (T) formed inside the base material (2) is difficult to visually recognize, since the line-shaped processing marks (M1, M2) are clearly formed on a surface of the metal foil (5), the modified layer (T) can be easily and visually recognized. Therefore, based on the line-shaped processing marks (M1, M2), a position of the modified layer (T), that is, the irradiation position of the laser beam at the time of formation of the modified layer (T) can be grasped. For this reason, a user can acquire a positional relationship between the irradiation position of the laser beam and a surface damage (LD) formed by the laser beam reaching the surface of the base material (2), so that the influence of irradiation of the laser beam on the surface of the workpiece can be easily verified.
