摘要: In a method for anisotropic etching of a structure in an electrically conductive substance to be etched, use is made of an etchant which in concentrated solution is usable for isotopic etching of structures in the substance to be etched. The substance to be etched is contacted with the etchant in a solution which is so diluted that the etchant is unusable for isotropic etching. The etchant is subjected, adjacent to the substance to be etched, to an electric field of such a strength that anisotropic etching of the substance to be etched is accomplished. Moreover, an etching fluid is described, comprising an etchant in dilute solution, in which the etchant is present in a concentration of 200 mM at most, and use of such an etching fluid for making structures which are 50 &mgr;m or less is also described.

摘要: A method of making, by etching, depressions in selected portions of an etching surface of an electrically conductive etching material, the depressions forming an etching pattern, comprises the step of contacting the etching material with an etchant. A passivating layer is formed on the etching material which layer decreases or stops the etching capability of the etchant on the surface and which is dissolved in a chemical reaction when exposed to electromagnetic radiation. An electrode with electrically conductive electrode portions in selected portions of an electrode surface is provided, the electrode portions forming an electrode pattern corresponding to the etching pattern. The electrode is arranged in contact with the etchant and with the electrode portions facing the etching surface of the etching material, an electric voltage is applied between the electrode and the etching material, and the etching material is exposed to electromagnetic radiation essentially perpendicular to the etching surface.

摘要: An apparatus and a method in connection with the lithography of structures on a micro or nanometer scale. A nano-imprinting apparatus according to an embodiment of the invention comprises two rotatably mounted rollers for transferring a pattern of micro or nanometer size to the substrate to be patterned. A first rotatably mounted roller has a patterned circumferential surface for transferring a pattern from the first rotatably mounted roller to a deformable substrate by contacting the patterned surface with the substrate. A second rotatably mounted roller has a principally smooth circumferential surface which faces the patterned surface of the first rotatably mounted roller. Furthermore, the second rotatably mounted roller is rotatably coupled with the first rotatably mounted roller for synchronized rotation of the first and second rollers. The substrate is movable between the first and second rollers such that, when these rollers rotate with respect to each other, the patterned surface of the first rotatably mounted roller comes into contact with the substrate whereby this pattern is transferred from the patterned surface to the substrate.

摘要: The invention relates to a two-step process for transferring a pattern from a template (1) to a target surface of a substrate, by creating an intermediate flexible polymer stamp (5) from the template in a primary step, and then using the polymer stamp to make an imprint in a radiation-sensitive moldable layer on the target surface in a secondary step. In the secondary step, the process steps of pressing the polymer stamp and the substrate against each other, UV exposure of the moldable layer through the polymer stamp, and postbaking of the radiated moldable layer, are all performed at a control constant temperature, in order to eliminate damages to the pattern created in the moldable layer caused by thermal expansion effects.
