Abstract
The invention relates to a method for producing a plurality of components (), wherein a carrier composite () is provided with a coherent base body () and a wafer composite () is provided with a coherent semiconductor body composite () and a substrate (). The wafer composite is connected to the carrier composite to form a common composite. In a subsequent method step, a plurality of separation channels () are generated at least through the base body () to form a grid structure (), which determines the dimensions of the components () to be produced. A passivation layer () is shaped in such a way that it covers the side surfaces of the separation channels (). Finally, the common composite is separated, wherein the substrate () is removed from the semiconductor body composite () and the common composite is separated along the separation channels () to form a plurality of components ().
