摘要： In order to provide a scanning probe microscope capable of measuring with high throughput distribution information relating to local characteristics of a sample concurrently with accurate three-dimensional shape information of the sample without damaging the sample, the speed of approach to each measurement location is increased by controlling the approach of the sample and probe by the provision of a high-sensitivity proximity sensor of the optical type. Also, additional information relating to the distribution of material quality on the sample can be obtained without lowering the scanning speed by: applying a voltage to the probe, or measuring the response on vibrating the probe, or detecting the local optical intensity of the sample surface concurrently with obtaining sample height data and concurrently with the contact period with the sample, whilst ensuring that the probe is not dragged over the sample, by bringing the probe into contact with the sample intermittently.

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： In a displacement measurement apparatus using light interference, a probe light path is spatially separated from a reference light path. Therefore, when a temperature or refractive index distribution by a fluctuation of air or the like, or a mechanical vibration is generated, an optical path difference fluctuates between both of the optical paths, and a measurement error is generated. In the solution, an optical axis of probe light is brought close to that of reference light by a distance which is not influenced by any disturbance, a sample is irradiated with the probe light, a reference surface is irradiated with the reference light, reflected light beams are allowed to interfere with each other, and a displacement of the sample is obtained from the resultant interference light to thereby prevent the measurement error from being generated by the fluctuation of the optical path difference.
