Abstract
The invention relates to a method for separating at least one solid-state layer () from at least one solid (). The method according to the invention includes the steps of: producing a plurality of modifications () by means of laser beams in the interior of the solid () in order to form a separation plane (); producing a composite structure by arranging or producing layers and/or components () on or above an initially exposed surface () of the solid (), the exposed surface () being part of the solid-state layer () to be separated; introducing an external force into the solid () in order to create stresses in the solid (), the external force being so great that the stresses cause a crack to propagate along the separation plane (), wherein the modifications for forming the separation plane () are produced before the composite structure is produced.
