    摘要: A scanning probe microscope has an XY scanner for making a probe scan a sample surface, an approach and separate drive element for making the probe approach to the sample surface at a sampling position and separate the probe from the sample surface during movement between the sampling positions, and a servo controller for holding the distance between the probe and the sample surface at a reference distance during measurement at the sampling position. A plurality of scattered measurement locations are set away from each other as sampling positions. The approach and separation movements are performed at each sampling position. When measuring the surface by the probe at a sampling position and while making the probe move between sampling positions, servo control by the servo controller is continued. This makes it possible to quickly measure the surface by a simple controller and possible to measure a wide area or measure a high aspect ratio. When making the probe approach to the sample surface for measurement at the sampling position, it is also possible to cause a scan motion for tandem movement at an equal speed and in the same direction as the scan motion by the XY scanner.

The Y fine movement mechanism arranged to the X moving section, has other two pairs of parallel-plate flexural sections, a Y moving section movable in the Y direction, connected to the X moving section through the other two pairs of parallel-plate flexural sections, and two Y direction piezoelectric actuators causing the Y moving section to move relatively to the X moving section.

    摘要: With a scanning probe microscope, if a plurality of sample properties are measured using a scanning scheme of allowing a probe to approach and withdraw from a sample, the sample properties need to be accurately and reliably detected in the minimum required measurement time. Further, the acting force between the probe and the sample varies depending on the type of the probe and the wear condition of a probe tip. Thus, disadvantageously, property values acquired using different probes cannot be compared with one another unless the artifactual effect of the measuring probes are eliminated. In accordance with the present invention, with a scanning probe microscope, the probe is brought into intermittent contact with the sample, while driving means repeatedly allows the probe to approach and withdraw from the sample with a variable amplitude. The sample property is thus acquired at a high speed. Further, a calibration sample is used in a given environment (given temperature and humidity) to acquire a force curve for at least one point. Information obtained from the force curve is used to correct measurements to display the distribution of the sample property.
