Claim Text:
1. A conductive atomic force microscope comprising: a plurality of probe structures, each of which including a probe and a cantilever connected thereto; a power supply unit configured to apply a bias voltage to each of a sample object and a measurement object; a current detecting unit configured to detect a first current flowing between the sample object and each of the plurality of probe structures, detect a second current flowing between the measurement object and each of the plurality of probe structures, and calculate representative currents with respect to the sample object and the measurement object based on the first and second currents, respectively; and a control unit configured to calculate a ratio between representative currents of the sample object measured by each of the plurality of probe structures, calculate a scaling factor for scaling the representative current with respect to the measurement object measured by each of the plurality of probe structures, and determine a reproducible current measurement value based on the second current and the scaling factor.
