Patent number: 10209630Abstract: A scanning probe nanolithography system comprising a probe to create nanostructures line (60) by line through writing said nanostructures (74) pixel by pixel along lines (61) on a sample. A positioning system is adapted to provide a positioning of the probe at a sequence of predetermined positions to the sample and its surface towards the probe and a control unit (50) is provided to control the positioning system for positioning the probe for a pixel-wise writing of said lines (61) through a writing unit. It further comprises a sensor unit adapted to detect a predetermined property of the written nanostructure (74), the sensor unit being connected to the control unit to adapt the control signals to be provided to the writing unit for writing the following line (61; 62) based on the measured signals (65; 66) of the predetermined property.Type: GrantFiled: September 16, 2014Date of Patent: February 19, 2019Assignee: SwissLitho AGInventors: Felix Holzner, Michael Zientek, Philip Paul, Armin Knoll, Colin Rawlings

Patent number: 9921486Abstract: The present invention provides a method for multiscale patterning of a sample. The method includes: placing the sample in an apparatus having both thermo-optical lithography capability and thermal scanning probe lithography capability; and patterning two patterns onto the sample, respectively by: thermo-optical lithography, wherein light is emitted from a light source onto the sample to heat the latter and thereby write a first pattern that is the largest of the two patterns; and thermal scanning probe lithography, wherein the sample and a heated probe tip are brought in contact for writing a second pattern that has substantially smaller critical dimensions than the first pattern. There is also provided an apparatus for multiscale patterning of a sample.Type: GrantFiled: November 13, 2014Date of Patent: March 20, 2018Assignee: SWISSLITHO AGInventors: Urs T Duerig, Stefan Fringes, Felix Holzner, Armin W Knoll
