    Abstract: Concepts presented herein relate to a portable device (10) that includes a frame (20) and a fixture (22) for engaging a mechanical probe (12) to be calibrated. The fixture (22) can be a platform of hard material that receives pushing action of the mechanical probe (12). A displacement sensor (30) senses position of the platform (22) with respect to the frame (20). An actuator is coupled to the displacement sensor and a controller (32) is coupled to the actuator. The controller (32) operates the actuator to cause the platform (22) to move to a position (as indicated by the displacement sensor (30)), while the force required to cause the displacement is measured with a force sensor.

    Abstract: An improved method is provided for performing nanomanipulations using an atomic force microscope. The method includes: performing a nanomanipulation operation on a sample surface using an atomic force microscope; determining force data for forces that are being applied to the tip of the cantilever during the nanomanipulation operation, where the force data is derived along at least two perpendicularly arranged axis; and updating a model which represents the topography of the sample surface using the force data.

    Abstract: A scanning electron microscope (SEM) is calibrated for the effects of local charging on a measured critical dimension (CD) of a wafer by first calibrating the microscope with respect to a calibration wafer with a known CD. Local charging on a wafer may be measured as a local landing energy (LLE) so that a scale factor based on a ratio of LLEs for the measurement wafer and a calibration wafer is used to correct a measured CD for the measurement wafer.

    Abstract: Electron optical aberrations of an energy filtering system (120) of an energy filtering transmission electron microscope (100) (EFTEM) are automatically corrected under computer control to set up the EFTEM for use. Optics of the electron microscope preceding an energy filter are used to scan the beam at the entrance to the filter in a pattern corresponding to a defined geometry. The beam can either be finely focused to yield a spot at each position visited during the pattern scan, or the beam can be spread out and imprinted with a well-defined intensity distribution, such as normally occurs due to passage of the beam through a specimen, so that its relative scanned displacements can be assessed using cross-correlation techniques. In the case of the finely focused beam, electron images of the scanned pattern directly yield a spot pattern image. Deviations of the recorded spot pattern image from the defined scan geometry reflect the imaging aberrations introduced by the energy filter. In the case of the spread out beam, post-filter electron images of the scanned beam are cross-correlated with an image of the beam taken without scanning yielding cross-correlation peak images that give the effective displacement of each scanned beam position due to the aberrations/distortions of the filter. Summing the cross-correlation peak images again yields a spot pattern image that is equivalent to that obtained in the focused beam case. Deviations of the recorded spot pattern image from the defined scan geometry are analyzed to assess and subsequently correct aberrations introduced by the energy filter.

    Abstract: The present document relates to a method of calibrating, in a scanning probe microscopy system, an optical microscope. The optical microscope is configured for providing a reference data for positioning a probe tip on a surface of a substrate. The calibration is performed using a calibration structure being a spatial structure including features at different Z-levels relative to a Z-axis, the Z-axis being perpendicular to the surface of the substrate. The method comprises a step of obtaining, with the optical microscope, at least two images of at least a part of the calibration structure. The at least two images are focused in at least two different levels of the Z-levels. The method further comprises a step of determining a lateral shift, in a direction perpendicular to the Z-axis, of the calibration structure as depicted in the at least two images focused in the at least two different levels. The invention is further directed at a calibration structure, a substrate carrier and scanning probe microscopy device.
