Abstract
A method for producing a thin-film layer includes providing a layer stack on a carrier substrate, wherein the layer stack includes a carrier layer and a sacrificial layer, and wherein the sacrificial layer includes areas in which the carrier layer is exposed. The method includes providing the thin-film layer on the layer stack, such that the thin-film layer bears on the sacrificial layer and, in the areas of the sacrificial layer in which the carrier layer is exposed, against the carrier layer. The method includes at least partly removing the sacrificial layer from the thin-film layer in order to eliminate a contact between the thin-film layer and the sacrificial layer in some areas. The method also includes detaching the thin-film layer from the carrier layer.
