Abstract
The invention relates to a composite component made of a plurality of components, a modified sacrificial layer and a common intermediate carrier, in which the components each have a semiconductor body with an active zone, the semiconductor bodies being arranged on the intermediate carrier and being laterally spaced apart from one another by means of isolating trenches. The sacrificial layer is arranged in the vertical direction between the intermediate carrier and the semiconductor bodies, the sacrificial layer having a plurality of retaining elements between the semiconductor bodies and the common intermediate carrier, and the semiconductor bodies being mechanically connected to the intermediate carrier only by means of the retaining elements. The retaining elements are surrounded by cavities in lateral directions. The semiconductor bodies are designed to be detachable from the intermediate carrier, wherein the retaining elements release the semiconductor bodies from the intermediate carrier under mechanical strain or by means of irradiation or by means of etching. The invention further relates to a component having a semiconductor body which is detached from a composite component of this type, and to a method for producing a plurality of components of this type.
