Abstract

See full text

A method for cutting off at least one portion, in particular a wafer, from a solid body is contemplated. The method includes: modifying the crystal lattice of the solid body by means of a modifier, wherein a number of modifications are produced to form a nonplanar, in particular convex, detachment region in the interior of the solid body, wherein the modifications are produced in accordance with predetermined parameters, wherein the predetermined parameters describe a relationship between a deformation of the portion and a defined further treatment of the portion, detaching the portion from the solid body.
