Scanning probe microscope nano-oxidation is carried out on H-passivated Si(001) surfaces using a humidity control atomic force microscope (AFM) in contact and dynamic modes. To achieve high precision nano-oxidation at large scale, the original tube-scanner-based AFM unit is modified: horizontal movement of the whole sample block (sample stage and the scanner) is operated by an additional XY piezo stage, whilst its vertical movement is controlled by a piezo tube-scanner. The high linearity of the horizontal movement is demonstrated by high resolution oxide patterns which are fabricated after the instrumental modification using standard AFM cantilevers and a modified AFM cantilever with an added carbon nano-tube on tip. © 2004 Elsevier B.V.
