The invention provides a composite structure for microelectronic components having a self-supporting metal plate, an electrically insulating layer adhering to the metal plate, and a functional layer adhering to the insulating layer for the application of at least one microelectronic component. An at least largely monocrystalline information layer which covers the metal plate at points is applied to the self-supporting metal plate. The regions of the surface of the metal plate which are free of the information layer are provided with the insulating layer. When the surface of the information layer is exposed at least in regions, the functional layer is deposited on the insulating layer and on the exposed information layer. The crystal information required for an epitaxial deposition of the functional layer is taken from the information layer.
