Filed: 1992-12-25
Abstract: PURPOSE:To provide a scanning type probe microscope device for easily executing accurate setting and estimation of the interval between a sample and a probe, and for carrying out probe scanning at a fixed interval between the sample and the probe. CONSTITUTION:The expanding operation of an XYZ driving piezoelectric body 27 on which a sample 26 is loaded, is controlled by a microcomputer 21, and the body can be moved in any directions X, Y, Z in a very fine mode. The front end part of a cantilever 31 is moved closer to the surface of the sample, and scanning is carried out at predetermined vibration (an amplitude signal S2) or non-vibration (a displacement signal S1) by means of an excitation piezoelectric body 32. The central value of the displacement of the probe detected by an MFM (scanning type magnetic microscope), and a dependency curve of the interval between the vibration amplitude value of the probe and the sample probe is measured. The two curves are processed into image, and the vibration amplitude value in the measurement of an isodynamic force grading image is set, while the interval between the sample and the probe in measurement of a constant-height image is set and estimated, and the displacement thus obtained is displayed on an image screen by a host computer 22.
