- phase feedback system will be described as a reference example of the present invention.
- FIG. 5 is a system configuration diagram of a scanning probe microscope apparatus (phase feedback method) showing a reference example of the present invention.
- the phase feedback system has a configuration in which the second controller 7 in FIG. 4 is not required, and is a system that monitors only the phase difference signal. That is, only the phase difference signal is input to the first controller 21, and the frequency control signal is not input to the signal generator 22, but the signal is generated independently.
- the distance between the cantilever 4 and the sample 1 (Z-axis position) is controlled so that the phase difference detected by the phase difference detection means 6 becomes zero.
- This control means that the interaction force is controlled to be constant.

- a second switch 32 that can turn off the signal is arranged to switch between the phase feedback method and the tracking separate excitation method shown in FIG.
- the distance between cantilever 4 and sample 1 must be close to a nanometer order distance. Since the movable range of a Z-axis scanner (usually a piezoelectric element) is only about a micrometer, a coarse motion mechanism with a movable range on the order of millimeters is required.
- the frequency of the signal generator 9 is changed in order to change the distance between the cantilever 4 and the sample 1, and as a result, the distance is controlled so that the frequency matches the resonance frequency. Therefore, this control method is valid only within the movable range of the Z-axis scanner. In other words, the phase feedback method does not hold in situations where distance is given first. Therefore, the phase feedback method cannot be used when the Z-axis coarse movement mechanism is used.
- this problem is solved by using the tracking separate excitation method while the cantilever 4 and the sample 1 are brought close to a predetermined distance using the coarse motion mechanism, and then the control method is phase feedback. It can be solved by switching to the method.
- the vibration amplitude can be stabilized even if the Q value of the cantilever 4 is low.
- the phase difference between the drive signal and the detection signal reflects the difference between the frequency of the drive signal and the resonance frequency of the cantilever 4, and if the phase difference changes when the cantilever 4 is scanned with respect to the sample 1 This means that the interaction force between cantilever 4 and sample 1 has changed.
- the resonance frequency always matches the driving frequency by changing the distance between the cantilever 4 and the sample 1 so that the phase difference becomes zero (in other words, the cantilever 4 and the sample 1 can be matched).
- 1) The distance between cantilever 4 and sample 1 is acquired as a concavo-convex image.
- Get The distance between the cantilever 4 and the sample 1 is changed so that the interaction force is constant by forming another force or another feedback loop, and this change in distance is acquired as an uneven image.
