Patent number: 11630394Abstract: Disclosed is a method for lithographically producing a target structure on a non-planar initial structure by exposing a photoresist by means of a lithography beam. In the inventive method, the topography of a surface of the non-planar initial structure is detected. A test parameter for the lithography beam is used and an interaction of the lithography beam with the initial structure and the resultant change in the lithography beam and/or the target structure to be produced are determined. A correction parameter for the lithography beam is determined such that the change in the lithography beam and/or the target structure to be produced that is caused by the interaction of the lithography beam with the initial structure is reduced. The desired target structure on the initial structure is produced by exposing the photoresist by means of the lithography beam using the correction parameter.Type: GrantFiled: September 10, 2021Date of Patent: April 18, 2023Assignee: Karlsruhe Institute of TechnologyInventors: Christian Koos, Tobias Hoose, Philipp Dietrich, Matthias Blaicher, Maria Laura Gödecke, Nicole Lindenmann

Publication number: 20220350239Abstract: Method (and apparatus) for producing a 3D target structure in lithographic material. Focus region of a laser writing beam travels through a scanning manifold through the lithographic material. In the focus region of the laser writing beam, an exposure dose is irradiated into the lithographic material, and a structure region is locally defined. At least one exposure data set which represents a local exposure dose for the scan manifold as a function of location is determined. A structure which approximates the target structure is defined based on at least one exposure data set. This structure is analyzed and at least one analysis data set which represents the analyzed structure is determined. Deviation data set which represents deviations of the already defined structure from the target structure is determined. At least one correction exposure data set is determined. Correction structure based on the at least one correction exposure data set is defined.Type: ApplicationFiled: April 4, 2022Publication date: November 3, 2022Applicant: Nanoscribe Holding GmbHInventors: Nicole LINDENMANN, Matthias BLAICHER, Jörg HOFFMANN

Publication number: 20220011677Abstract: An optical system and a method for producing it is disclosed. The optical system has at least two separate optical components and an optical connection between them. In the inventive method, first and second optical component are provided, each having respective beam profiles. An arrangement of the first and second optical components and the form and target position of at least one beam-shaping element are specified. The beam-shaping element is produced using a three-dimensional direct-writing lithography method in situ at the target position to thereby obtain an optical component supplemented by the beam-shaping element. The supplemented optical component is placed and fixed on common base plate to thereby obtain the optical system. The optical systems produced with the present method can be used in optical data transfer, measurement technology and sensors, life sciences and medical technology, or optical signal processing.Type: ApplicationFiled: September 28, 2021Publication date: January 13, 2022Inventors: Philipp-Immanuel Dietrich, Christian Koos, Matthias Blaicher, Ingo Reuter, Yilin Xu
