Techniques for determining a characteristic of a sample using an atomic force microscope including a cantilever having a probe attached thereto, including positioning the sample within a cell and sliding the probe over a sliding zone of the sample within the cell. Lateral and vertical deformations of the cantilever are detected using the atomic force microscope as the probe is slid over the sliding zone. One or more characteristics are determined based on the detected lateral deformations of the cantilever.

Systems and approaches for semiconductor metrology and surface analysis using Secondary Ion Mass Spectrometry (SIMS) are disclosed. In an example, a secondary ion mass spectrometry (SIMS) system includes a sample stage. A primary ion beam is directed to the sample stage. An extraction lens is directed at the sample stage. The extraction lens is configured to provide a low extraction field for secondary ions emitted from a sample on the sample stage. A magnetic sector spectrograph is coupled to the extraction lens along an optical path of the SIMS system. The magnetic sector spectrograph includes an electrostatic analyzer (ESA) coupled to a magnetic sector analyzer (MSA).

The present invention relates to a scanning probe microscope having: (a) a scan unit embodied to scan a measuring probe over a sample surface in a step-in scan mode; and (b) a self-oscillation circuit arrangement configured to excite the measuring probe to a natural oscillation during the step-in scan mode.

A method for inspecting a nozzle includes producing a jet from the nozzle, moving the nozzle to cause the jet to approach a stylus of a touch probe, generating a contact signal under a force acting on the stylus, and determining that the jet is appropriate in response to a contact signal received first after the jet has an axis at a distance from the stylus that is equal to or less than a first normal distance calculated from a normal jet shape.

Method and system for performing characterization of a sample using an atomic force microscopy system. An actuation signal is provided to a photo-thermal actuator which is configured to excite the probe by means of an optical excitation beam incident on the cantilever. The probe is configured to be bendable by means of the optical excitation beam impinging on it. The actuation signal is configured to include at least one modulation frequency. The probe tip motion is monitored for determining at least a subsurface characterization data.
