Abstract
In one aspect, a method of nanolithography is provided, the method comprising providing a substrate; providing a scanning probe microscope tip; coating the tip with a deposition compound; and subjecting said coated tip to a driving force to deliver said deposition compound to said substrate so as to produce a desired pattern. Another aspect of the invention provides a tip for use in nanolithography having an internal cavity and an aperture restricting movement of a deposition compound from the tip to the substrate. The rate and extent of movement of the deposition compound through the aperture is controlled by a driving force.
