The invention relates to a method for making a structure with at least a first polymer layer and a second polymer layer, each made from a polycarbonate polymer based on bisphenol A, between the polymer layers a component being arranged, comprising the following steps: a) the component is arranged on the first polymer layer or placed in a depression of the first polymer layer, b) the first polymer layer is coated on the side, on which or in which the component is arranged, at least in the region of the component with a liquid preparation comprising a solvent or a mixture of solvents and a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenyl cycloalkane, c) optionally a drying step is made after step b), d) after step b) or step c), the second polymer layer is placed on the first polymer layer, covering the component, e) the first polymer layer and the second polymer layer are laminated with each other under pressure, at a temperature from 120&#xb0; C. to 180&#xb0; C. and for a defined time.
