Abstract
The invention provides methods of nanolithography and products therefor and produced thereby. In particular, the invention provides a nanolithographic method referred to as high force nanografting (HFN). HFN utilizes a tip (e.g., a scanning probe microscope (SPM) tip such as an atomic force microscope (AFM) tip) to pattern a substrate passivated with a resist. In the presence of a patterning compound, the tip is used to apply a high force to the substrate to remove molecules of the resist from the substrate, whereupon molecules of the patterning compound are able to attach to the substrate the form the desired pattern.
