Abstract: A peel-off layer is finally formed in an area, i.e., a first inner area or a second inner area, in a workpiece that is closer to the center of the workpiece among a plurality of areas. The workpiece has a cylindrical shape, so that the second inner area is wider than the other areas, e.g., the second outer area, in which the peel-off layers are formed. Consequently, when the peel-off layer is finally formed in the second inner area, the internal stresses in the workpiece are dispersed in a wider range than when the peel-off layer is finally formed in the second outer area. Thus, large cracks thicknesswise of the workpiece are prevented from being developed from modified regions contained in the peel-off layer. Therefore, the amount of workpiece material to be disposed of in subsequent steps is reduced, resulting in increased manufacturing productivity.
