| Outline of Final Research Achievements |
In this research, a precision measurement system by using a microprobe has been developed for dimensional measurement of micrometric features. The microprobe can detect local attractive force owing to thin water layer that exists at the measuring surface. Since the thickness of the water layer is several tens nanometer in general, the probe can realize dimensional measurement with nanometric resolution. In order to reduce the influence of the difference of thickness of water layer, on-line qualification of the effective diameter of the probe tip ball has introduced. With respect to the assurance of the measurement results, error analysis was carried out based on the geometrical model of the measurement system. Consequently, nanometric measurement uncertainty could be achieved for the dimensional measurement of micro-features.
