摘要： In the case of measuring a pattern having a steep side wall, a probe adheres to the side wall by the van der Waals forces acting between the probe and the side wall when approaching the pattern side wall, and an error occurs in a measured profile of the side wall portion. When a pattern having a groove width almost equal to a probe diameter is measured, the probe adheres to both side walls, the probe cannot reach the groove bottom, and the groove depth cannot be measured. When the probe adheres to a pattern side wall in measurements of a microscopic high-aspect ratio pattern using an elongated probe, the probe is caused to reach the side wall bottom by detecting the adhesion of the probe to the pattern side wall, and temporarily increasing a contact force between the probe and the sample. Also, by obtaining the data of the amount of torsion of a cantilever with the shape data of the pattern, a profile error of the side wall portion by the adhesion is corrected by the obtained data of the amount of torsion.

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.

摘要： This probe control method is applied to the scanning probe microscope having a probe section with a probe pointed at a sample, a detection section for detecting physical quantity between the sample and the probe, a measurement section for measuring the surface of the sample to obtain the surface information on the basis of the physical quantity when scanning the sample surface by the probe, and a movement mechanism with at least two degree of freedom. The probe control method has steps of moving the probe in a scanning direction different from the contact direction while making the probe come into contact with the sample surface, detecting the torsional state of the probe during the movement of the probe, and adjusting either or both of the rate in the scanning direction and the force in the contact direction on the basis of the detected value obtained by the detection step.
