Abstract

Nanoscale metrology is an important factor in the microchip industry, setting the limit to the degree of complexity of manufactured circuits. Atomic Force Microscopy (AFM) is a central method of nanoscale metrology, which utilizes Van der Waals (VdW) interaction forces between a tip connected to a beam and the measured specimen. One of AFM metrology's limitations is its inability to reproduce complex topographies due to the size of the interacting tip. The present research proposes to substitute the AFM tip with a nanowire, allowing the insertion of the nanowire into complex topographies and the measurement of the VdW interactions. By incrementally moving the nanowire and resonating it, it is possible to reproduce the distributed VdW interactions between the beam and the specimen, and consequently, accurately approximate the specimen's topography. This method is validated on an up-scaled magnetic experimental system, which substitutes the VdW potential with magnetic forces.
