| Outline of Final Research Achievements |
By locally irradiating an atmospheric pressure plasma jet (APPJ), we have developed a nanofabrication/analysis system capable of surface microfabrication and composition spectroscopic analysis of the fabrication state. This system locally irradiates APPJ from the tip of the nanopipette, which is positioned with high precision by a scanning probe microscope that uses a nanopipette with a microscopic aperture at the tip. By adding a small amount of reactive gas to the plasma source gas, we have improved the processing efficiency due to active species. In addition, processing efficiency was improved by enabling irradiation with high-frequency plasma. Furthermore, we have developed a device that analyzes fabricating phenomena by plasma emission spectroscopy and demonstrated its effectiveness.
