摘要: Method of tuning parameter settings for performing acoustic scanning probe microscopy for subsurface imaging, scanning probe microscopy system, and computer program product. This document relates to a method of tuning a scanning probe microscopy system. The method comprises: a) applying an acoustic vibration signal comprising a first frequency and a second frequency to a sample; b) at a first position of the probe tip, sweeping the first frequency across a first frequency range, and obtaining a first signal; c) at a second position of the probe tip, sweeping the first frequency across at least said first frequency range, and obtaining a second signal; d) analyzing the first and second signals to obtain a difference characteristic dependent on the first frequency. The first and second position are selected such that a subsurface structure of the sample at the first and second position is different.

摘要: Apparatus and techniques presented combine the features and benefits of amplitude modulated (AM) atomic force microscopy (AFM), sometimes called AC mode AFM, with frequency modulated (FM) AFM. In AM-FM imaging, the topographic feedback from the first resonant drive frequency operates in AM mode while the phase feedback from second resonant drive frequency operates in FM mode. In particular the first or second frequency may be used to measure the loss tangent, a dimensionless parameter which measures the ratio of energy dissipated to energy stored in a cycle of deformation.

摘要: Improvements for rapidly calibrating and automatically operating a scanning probe microscope are disclosed. A central component of the SPM is the force transducer, typically a consumable cantilever element. By automatically calibrating transducer characteristics along with other instrumental parameters, scanning parameters can be rapidly and easily optimized, resulting in high-throughput, repeatable and accurate measurements. In contrast to dynamic optimization schemes, this can be accomplished before the surface is contacted, avoiding tip or sample damage from the beginning of the measurement process.

摘要: A method of calibrating a contact probe having a contact element includes measuring with the contact probe a first geometric property of a calibrated artefact and a second geometric property of the or a further calibrated artefact. The first and second geometric properties are such that a deviation between a measured value and the expected value, resulting from a difference between an effective diameter of the contact element and an assumed diameter used for determining the measured value, has the opposite sign for each of the first and second geometric properties. The method further includes identifying a difference in the effective diameter of the contact element from the assumed diameter including comparing deviations of the measured value to the expected value for each of the first and second geometric properties to determine whether there is a difference in the deviations.

In one embodiment, a method may include providing a probe of a measurement tool coupled to a positioning scanner; scanning a surface of a first sample with the surface at a first angle relative to the probe to attain a first profile; scanning the surface of the first sample with the surface at a second angle relative to the probe that is different than the first angle to attain a second profile; repeating the scannings to attain a plurality of first profiles and a plurality of second profiles; and determining a non-linearity of the positioning scanner using the different scanning angles to cancel out measurements corresponding to imperfections due to the surface of the sample. The non-linearity may be used to calibrate the positioning scanner.

摘要: A scanning probe microscope that facilitates the optical axis adjustment operation at the time of initial cantilever installation and at the time of cantilever replacement. During the optical axis adjustment operation, markers are displayed on the video camera image at the cantilever and laser light center of luminance locations, and the markers, which follow the movement of the laser light location, are visually monitored and superposed. Furthermore, optical axis adjustment for a new cantilever is performed using marker location coordinate data stored after the initial optical axis adjustment. Moreover, by setting the target location coordinates, the direction of movement of laser light and the distance to the target location can be ascertained numerically.

摘要: A scanning probe microscopy (SPM) inspection and/or modification system which uses SPM technology and techniques. The system includes various types of microstructured SPM probes for inspection and/or modification of the object. The components of the SPM system include microstructured calibration structures. A probe may be defective because of wear or because of fabrication errors. Various types of reference measurements of the calibration structure are made with the probe or vice versa to calibrate it. The components of the SPM system further include one or more tip machining structures. At these structures, material of the tips of the SPM probes may be machined by abrasively lapping and chemically lapping the material of the tip with the tip machining structures.
