Production of fixed structure division of high spatial resolution

摘要

Topic This invention the fixed structure division regards the method of producing with high spatial resolution. The substance which is modification possible the entry territory (7) is prepared inside by the optical signal (5). The optical signal (5), irradiates the part territory which is limited spatially appropriately, in order the entry territory which is detected by the optical signal (5) (7) inside the part territory another state of the substance which is different (C), to be set inside this part territory uniformly, this optical signal (5) the entry territory (7) is irradiated on. In this case, as for the part territory which is irradiated appropriately by the optical signal (5), the optical signal (5) the smallest strength of section (9) thing, and the saturation which are, in order to be obtained when modifying the substance by the optical signal, appropriately is irradiated the optical signal outside the part territory which is limited spatially (5) is irradiated. In this way, the diffraction limit of the structure division which is produced can be decreased.
