The aim of the invention is to create a permanent structure with high three-dimensional resolution. Said aim is achieved by supplying a substance in a writing zone (7), which can be modified with the aid of an optical signal (5). Said optical signal (5) is applied to the writing area (7) so as to specifically leave out a spatially limited partial area wherein a state (C) of the substance, which is different from the state in the partial areas of the writing zone (7) reached by the optical signal (5), is permanently adjusted. The partial area specifically omitted by the optical signal (5) represents a minimum local intensity (9) of the optical signal (5) while the optical signal (5) is applied outside the specifically omitted spatially limited partial area in such a way that saturation is reached when the substance is modified by means of the optical signal (5). Hence, it is possible to fall below the diffraction limit in the created structure. |
