  • Patent number: 10209630
    Abstract: 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.

  • Patent number: 9921486
    Abstract: 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.

  • Patent number: 9121108
    Abstract: A method for positioning nano-objects on a surface and an apparatus for implementing the method. The method includes: providing a first surface and a second surface in a position facing each other, where one or more of the surfaces exhibits one or more position structures having dimensions on the nanoscale; providing an ionic liquid suspension of the nano-objects between the two surfaces, where the suspension comprises two electrical double layers each formed at an interface with a respective one of the two surfaces, and the surfaces have electrical charges of the same sign; enabling the nano-objects in the suspension to position according to a potential energy resulting from the electrical charge of the two surfaces; and depositing one or more of the nano-objects on the first surface according to the positioning structures by shifting the minima of the potential energy towards the first surface.

  • Patent number: 8821965
    Abstract: The invention notably concerns a method for depositing nano-objects on a surface. The method includes: providing a substrate with surface patterns on one face thereof; providing a transfer layer on said face of the substrate; functionalizing areas on a surface of the transfer layer parallel to said face of the substrate, at locations defined with respect to said surface patterns, such as to exhibit enhanced binding interactions with nano-objects; depositing nano-objects and letting them get captured at the functionalized areas; and thinning down the transfer layer by energetic stimulation to decompose the polymer into evaporating units, until the nano-objects reach the surface of the substrate.
