    Abstract: A method of investigating a sample surface. A probe is brought into close proximity with a first sample and scanned across the first sample. A response of the probe to its interaction with the sample is monitored using a detection system and a first data set is collected indicative of said response. The probe and/or sample is tilted through a tilt angle. The probe is scanned across the first sample or across a second sample after the tilting step, and a response of the probe to its interaction with the scanned sample is monitored using a detection system and a second data set is collected indicative of said response. The method includes the additional step of analysing the first data set prior to tilting the probe and/or sample in order to determine the tilt angle.

    Abstract: A method includes generating, using a sensor, a data signal. The data signal includes a first component based on a motion in a first direction of an actuator configured to provide motion between a sample and a probe in the first direction, the first direction substantially in the plane of the sample; and a second component based on at least one of topographic variations of the sample in a second direction, and a materials property of the sample. The method further includes generating, using a processor, a compensatory signal based on the first component of the data signal generated by the sensor; and providing the compensatory signal to the actuator.

    Abstract: A method and apparatus for scanning multiple scanning probe microscopes in close proximity, to scan overlapping scan areas at the same time while avoiding collision employs a control system (130) providing drive signals to a first Atomec Force Microscope (AFM) (148a) and calculated drive signals to additional AFMs (148b and 148c) based on the first drive signals and the relative position of the additional AFMs to the first ASM for consistent spaced motion. Scanning and Failure Analysis (FA) probing of multiple feature of interest using multiple AFMs allows for reduced time for locating FA features to set up measurements.

    Abstract: Apparatus and methods are provided for using atomic force microscopy for profiling high aspect ratio features. Probe landing techniques include scanning prior to bringing the probe into contact with the feature. In one embodiment, the probe assembly cantilever is brought into contact with the feature and subsequent scanning is used to locate the feature with the probe. In another embodiment, the probe is moved in a scanning pattern in progressively lower horizontal planes until the probe contacts the sample feature. Also described is a deconvolution technique for deconvolving the sample image and a technique for measuring the tip radius of the feature.

    Abstract: A method of measuring a sample with a probe, the probe comprising a cantilever mount, a cantilever extending from the cantilever mount to a free end, and a probe tip carried by the free end of the cantilever, the method comprising: taking a series of sidewall measurements of a sidewall of the sample with the probe; and analysing the series of sidewall measurements to determine a characteristic of the sidewall. The sidewall measurements are taken during a sidewall measurement cycle, comprising a pair of sidewall measurement drive phases. The pair of sidewall measurement drive phases comprises a first drive phase in which the probe is driven down next to the sidewall followed by a second drive phase in which the probe is driven up next to the sidewall. During one of the sidewall measurement drive phases the probe tip interacts with the sidewall, and the series of sidewall measurements are taken by measuring an angle of the cantilever as the probe tip interacts with the sidewall during the one of the sidewall measurement drive phases.

    Abstract: A system and method of operating an atomic force microscope (AFM) that includes providing relative scanning motion between a probe of the AFM and a sample in a slow scan direction of a data scan to generate a reference image (plane) of a region of interest. Then, relative scanning motion between the probe and the sample is provided in a fast scan direction of a final data scan to generate a data image. By mapping the data image against the reference image in real-time during the supplying step, the preferred embodiments generate a final drift corrected data image without post-image acquisition processing.

    Abstract: A method of imaging a surface using a scanning probe microscope, the scanning probe microscope comprising a probe having a cantilever extending from a base support (2) to a free end, and a probe tip carried by the free end of the cantilever, and a steering mirror (13), the method comprising: scanning the probe laterally across the surface so that the probe follows a scanning motion across the surface; steering a detection beam onto the probe via the steering mirror, the detection beam reflecting from the probe in the form of a return beam; moving the steering mirror so that the detection beam follows a tracking motion which is synchronous with the scanning motion and the detection beam remains steered onto the probe by the steering mirror; using the return beam to obtain image measurements, each image measurement being indicative of a measured height of a respective point on the surface; obtaining an associated height error measurement for each point on the surface by comparing a target value of the steering mirror position to the actual position of the steering mirror position, each height error measurement being indicative of a respective error in the measured height; and using the height error measurements to correct the image measurements so as to generate corrected image measurements.

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.

    Abstract: A calibration system is provided including an aperture layer, a lens layer, an optical filter, a pixel layer and a regulator. The aperture layer defines a calibration aperture. The lens layer includes a calibration lens substantially axially aligned with the calibration aperture. The optical filter is adjacent the lens layer opposite the aperture layer. The pixel layer is adjacent the optical filter opposite the lens layer and includes a calibration pixel substantially axially aligned with the calibration lens. The calibration pixel detects light power of an illumination source that outputs a band of wavelengths of light as a function of a parameter. The regulator modifies the parameter of the illumination source based on a light power detected by the calibration pixel.
