Abstract: A wafer manufacturing method for obtaining a wafer from an ingot includes the following procedure, steps or processes. A surface of one end side of the ingot in a height direction thereof is irradiated with a laser beam to which the ingot has transparency, thereby forming a peeling layer at a depth position corresponding to a thickness of the wafer from the surface. At this moment, the laser beam is irradiated such that a frequency of irradiation in a facet region is higher than that in a non-facet region. A wafer precursor as a portion between the surface of the ingot and the peeling layer is peeled from the ingot at the peeling layer. A major surface of a peeling body having a plate like shape, the peeling body being obtained by the wafer peeling step, is planarized electrically, chemically and mechanically, thereby obtaining a wafer.

Abstract: A surface of one end side of an ingot in a height direction thereof is irradiated with a laser beam having a permeability to the ingot, thereby forming a peeling layer at a depth position corresponding to a thickness of the wafer from the surface. A laser scanning irradiating the laser beam is performed for a plurality of times changing the irradiation position in a second direction while causing an irradiation position of the laser beam to move in a first direction. With a single laser scanning, a plurality of laser beams are irradiated in which irradiation positions are different in the first direction and the second direction.

The ingot has a given degree of transmittance to the laser beam. The wafer precursor is created by a portion of the ingot between the top surface of the ingot and the separation layer.
