| Outline of Final Research Achievements |
We have developed a novel and simple technique of three-dimension structure fabrication using a nanopipette filled with a metal colloidal solution. As for fabrication of the pillar, the pipette edge is contacted on the substrate, and then it was moved upward while keeping deposition of the metal colloidal solution. The diameter of the pillar is dependent on the aperture size of the pipette. To improve the reproducibility of the formation, the amount of deposition of the Au colloidal solution was controlled by feedback loop that maintains the pre-defined constant current under electrophoresis deposition. This technique would be expected as a fabrication method for micro and nanometer-scale devices.
