    Abstract: An atomic force microscope (2) is comprised of a microactuator (14) for preventing the transfer of any net forces from the microactuator (14) to a support structure (22). The net force transfer prevention can be achieved using either a multi-actuator assembly (230) including a primary microactuator (234) and a counteracting actuator (236) operating substantially out-of-phase with respect to the primary microactuator (234), or a single microactuator (332) mounted on the microactuator's support structure (314) to prevent momentum transfer to the support structure (22) during microactuator (14) operation.

    Abstract: An improvement to a phase controlled mechanical oscillator (111) consists of a balancing network (150) which generates a feedback signal from two different input signals with adjustable weights. One of these input signals is directly derived from the oscillator signal, the other is derived from a phase tracking loop (140). Using the balancing network, adjustments can be made to adapt the feedback to the mechanical properties, in particular to the Q factor, of the oscillator. In a preferred embodiment, all major components are working at an intermediate frequency level, generated by mixing the oscillator frequency with a reference frequency. As a major advantage of this (heterodyne) mixing, the bandwidth of any applied frequency detector can be narrowed, thus increasing the achievable signal-to-noise ratio.

    Abstract: The present invention describes an apparatus for nanolithography and a process for thermally controlling the deposition of a solid organic "ink" from the tip of an atomic force microscope to a substrate. The invention may be used to turn deposition of the ink to the substrate on or off by either raising its temperature above or lowing its temperature below the ink's melting temperature. This process may be useful as it allows ink deposition to be turned on and off and the deposition rate to change without the tip breaking contact with the substrate. The same tip can then be used for imaging purposes without fear of contamination. This invention can allow ink to be deposited in a vacuum enclosure, and can also allow for greater spatial resolution as the inks used have lower surface mobilities once cooled than those used in other nanolithography methods.
