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： A photoacoustic signal detecting method and apparatus for intensity-modulating light having a wavelength penetrating a sample such as a semiconductor device at a desired frequency, the light being emitted from a first light source, focusing the intensity-modulated light on the sample as a light spot, by changing the position of the sample and the optical constant of the means for focusing, scanning the light spot inside the sample in a depth direction thereof to detect the photoacoustic effect generated in the sample, and extracting information relative to the surface and inside of the sample and defect information therein. The photoacoustic effect is detected using an interferometer. Light incident on the sample surface for a second light source in order to obtain interference light and the interference light reflected from the sample surface are adjusted in response to a signal indicative of the depth of the light spot to detect optimum interference light. Light reflected from the sample surface when light emitted from a third light source is incident on the surface is detected through the focusing optical system to generate the signal indicative of the depth of the light spot.

摘要： A method and apparatus are disclosed for detection of surface defects and internal defect information of a sample, such as a semiconductor device, using the photoacoustic effect. Operationally, an intensity-modulated laser beam is provided having a predetermined desired frequency. The intensity-modulated laser beam is focused on the sample thereby inducing said photoacoustic effect inside the sample which is detected in two-dimensional directions of the sample so as to compose a two-dimensional photoacoustic image of the excited sample. Surface and internal information of the sample is then extracted from the two-dimensional photoacoustic image and an inverse filtering factor is in turn computed on the basis of a thermal impulse response of the particular sample for compensating degradation of the resolution of the actual photoacoustic image obtained. Lastly, the computed inverse filtering factor is then applied to the detected photoacoustic image to arrive at an image having greatly improved resolution.

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.
