    Abstract: A method for producing a composite component (100) and a composite component (100) comprising a plurality of components (10), a removable sacrificial layer (4), an anchoring structure (3) and a common intermediate carrier (90) are specified. The components each have a semiconductor body (2) comprising an active zone (23), are configured to generate coherent electromagnetic radiation and are arranged on the common intermediate carrier. The sacrificial layer is arranged in a vertical direction between the intermediate carrier and the components. The anchoring structure comprises a plurality of anchoring elements (3A, 3B), wherein the anchoring structure and the sacrificial layer provide a mechanical connection between the intermediate carrier and the components. Without the sacrificial layer, the components are mechanically connected to the intermediate carrier solely via the anchoring elements, wherein the anchoring elements are formed in such a way that under mechanical load they release the components so that the components are detachable from the intermediate carrier and are thus formed to be transferable.
