The invention relates to a method for cutting off at least one portion (4), in particular a wafer, from a solid body (2). The method comprises at least the following steps: modifying the crystal lattice of the solid body (2) by means of a modifier (18), wherein a number of modifications (19) are produced to form a nonplanar, in particular convex, detachment region (8) in the interior of the solid body, wherein the modifications (19) are produced in accordance with predetermined parameters, wherein the predetermined parameters describe a relationship between a deformation of the portion (4) and a defined further treatment of the portion (4), detaching the portion (4) from the solid body (2). |
