1. A method of producing self-supporting microstructures, thin flat parts, or membranes, which comprises:

  • a) providing a supporting frame with at least one opening;

    b) applying an adhesive film to the supporting frame such that the adhesive film spans the opening in the supporting frame flatly;

    c) applying an auxiliary layer to an underside of the adhesive film and adjacent regions of the supporting frame such that the auxiliary layer spans the opening in the supporting frame on one side flush with the supporting frame;

    d) removing the adhesive film;

    e) constructing component elements selected from the group consisting of microstructures, flat parts, and membranes on the common plane comprising the auxiliary layer and the supporting frame; and
