- SPM scanning probe microscope
- STM scanning tunneling microscope
- AFM atomic force microscope
- the present invention relates to a scanning probe microscope system that can automatically process a plurality of samples.
- a scanning tunneling microscope is a device that applies a bias voltage between a probe and a sample and uses a tunneling current generated there. Since the magnitude of the tunneling current is inversely proportional to the distance between the probe and the sample, for example, if the sample is scanned while adjusting the distance so that the tunneling current is constant, the displacement hysteresis force will show the fine shape of the sample surface. It can be recognized. Since it is possible to observe the atomic arrangement and structure of the surface on the atomic scale with a scanning tunneling microscope, it has been used for the evaluation of semiconductor devices and the observation of biomolecules. In order to observe with a scanning tunneling microscope, it is necessary to set up the microscope in a measurable state or to replace a deteriorated probe. Not suitable for processing.
