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.

Abstract: A method and a scanning probe microscope (SPM) for scanning a surface of a material. The method and SPM have a cantilever sensor configured to exhibit both a first spring behavior and a second, stiffer spring behavior. While operating the SPM in contact mode, the sensor is scanned on the material surface and a first spring behavior of the sensor (e.g. a fundamental mode of flexure thereof) is excited by deflection of the sensor by the material surface. Also while operating the SPM in contact mode, excitation means are used to excite a second spring behavior of the sensor at a resonance frequency thereof (e.g. one or more higher-order resonant modes) of the cantilever sensor to modulate an interaction of the sensor and the material surface and thereby reduce the wearing of the material surface.

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.
