Abstract
The invention relates to a method for creating a detachment zone () in a solid () in order to detach a solid portion (), especially a solid layer (), from the solid (), said solid portion () that is to be detached being thinner than the solid from which the solid portion () has been removed. The method according to the invention preferably comprises at least the steps of: providing a solid () which is to be processed and which is made of a chemical compound; providing a LASER light source; and subjecting the solid () to LASER radiation from the LASER light source so that the laser beams penetrate into the solid () via a surface () of the solid portion () that is to be cut off; the LASER radiation controlling the temperature of a predefined portion of the solid () inside the solid () in a defined manner such that a detachment zone () or a plurality of partial detachment zones () is formed; characterized in that the temperature produced by the laser beams in a predefined portion of the solid () is so high that the material forming the predefined portion is subject to modifications () in the form of a predetermined conversion of material.
