  • Publication number: 20050199046
    Abstract: A scanning probe microscope is capable of not only avoiding contact between a sample and a probe but also capable of shortening the time from detection of the sample during scanning by the probe to raising the probe to the top surface of the sample. A Z-axis controlling amount calculating mechanism controls a displacement amount of a cantilever or an oscillation amount in oscillating the cantilever so as to be constant, and a Z-axis driving mechanism drives in a Z direction the cantilever or a sample based on the controlling signal from the Z-axis controlling amount calculating mechanism. A driving range limiting device limits a driving range of the Z-axis driving mechanism, and a driving range setting device optionally sets the driving range so that the probe is lowered to a set position even in an area with no sample.

  • Patent number: 6941798
    Abstract: A scanning probe is microscope has a cantilever having a probe at a disal end thereof and an oscillator for generating a resonance signal near a resonance of the cantilever. A vibrating device receives the resonance signal as a driving signal for vibrating the cantilever.

  • Patent number: 6596992
    Abstract: In the first operation, the cantilever is oscillated at a frequency which is at opposite sides of a frequency band having a half value of an oscillation frequency f and amplitude A on a dependent curve (Q-curve). The cantilever oscillating frequency is far from an oscillation frequency (near a resonance point) where the cantilever is slow to damp, which enables the cantilever to quickly damp in accordance with a variation of a transient oscillation frequency after the probe comes into contact with the specimen, and allows the probe to follow the uneven surface state of the specimen.
