Abstract
A composite substrate () comprising a substrate body () and a utility layer () fixed on the substrate body (). A planarization layer () is arranged between the utility layer () and the substrate body (). A method for producing a composite substrate () applies a planarization layer () on a provided utility substrate (). The utility substrate () is fixed on a substrate body () for the composite substrate (). The utility substrate () is subsequently separated, wherein a utility layer () of the utility substrate () remains for the composite substrate () on the substrate body ().
