Outline of Final Research Achievements

This project started with the scope of development of micro-sensing device to simultaneously investigate the conductivity of multiple-electrodes of Integrated-Circuit (IC) or Micro-electro-mechanical systems (MEMS). However, throughout the research activities in the whole period, it has turned out that with the same mechanisms and/or structures, the usage as the device for measuring the surface potential of the specimen should be more feasible and effective rather than that for the conductivity. Thus, in the last research period, focusing on the usage of simultaneous measurement of the surface potential, the influence of mutual electrostatic interaction among multiple probes has been investigated, and then the calibration method to reduce the excessive influence is suggested according to the experimental and theoretical discussions.
