  • Patent number: 8707461
    Abstract: The method relates to a method of scanning a sample. Scanning a sample is typically done by scanning the sample with a probe along a multitude of parallel lines. In prior art scan methods a sample is scanned multiple times with a nominally identical scan pattern. The invention is based on the insight that the coherence between adjacent points in a direction along the scan direction is much better than the coherence of adjacent points perpendicular to the scan direction. By combining two images that are scanned perpendicular to each other, it should thus be possible to form an image making use of the improved coherence (due to shorter temporal distance) in both directions. The method thus involves scanning the sample with two scan patterns, the lines of one scan pattern preferably perpendicular to the lines of the other scan pattern. Hereby it is possible to use the temporal coherence of scan points on a line of one scan pattern to align the lines of the other scan pattern, and vice versa.

  • Patent number: 8646111
    Abstract: A novel way for constructing and operating scanning probe microscopes to dynamically measure material properties of samples, mainly their surface hardness, by separating the functions of actuation, indentation and sensing into separate dynamic components. The amplitude and phase shift of higher modes occurring at periodic indentations with the sample are characteristic values for different sample materials. A separate sensor cantilever, connected to the indentation probe tip, has the advantage of a high mechanical amplification of a desired higher mode while suppressing the actuation signal itself. The operational range of the sensor can be extended just by switching the actuation signal to another submultiple of the sensor cantilever's resonance frequency and/or by using more than one sensor cantilever for each indentation tip.

  • Patent number: 8170832
    Abstract: A method for Transmission Electron Microscopy (TEM) sample creation. The use of a Scanning Electron Microscope (SEM)—Scanning Transmission Electron Microscope (STEM) detector in the dual-beam focused ion beam (FIB)/SEM allows a sample to be thinned using the FIB, while the STEM signal is used to monitor sample thickness. A preferred embodiment of the present invention can measure the thickness of or create TEM samples by using a precise endpoint detection method. Preferred embodiments also enable automatic endpointing during TEM lamella creation and provide users with direct feedback on sample thickness during manual thinning. Preferred embodiments of the present invention thus provide methods for endpointing sample thinning and methods to partially or fully automate endpointing.

  • Patent number: 8108943
    Abstract: There is provided in one embodiment of the invention a method for analyzing a sample material using surface enhanced spectroscopy. The method comprises the steps of imaging the sample material with an atomic force microscope (AFM) to select an area of interest for analysis, depositing nanoparticles onto the area of interest with an AFM tip, illuminating the deposited nanoparticles with a spectrometer excitation beam, and disengaging the AFM tip and acquiring a localized surface enhanced spectrum. The method may further comprise the step of using the AFM tip to modulate the spectrometer excitation beam above the deposited nanoparticles to obtain improved sensitivity data and higher spatial resolution data from the sample material. The invention further comprises in one embodiment a system for analyzing a sample material using surface enhanced spectroscopy.

  • Patent number: 8051493
    Abstract: A method of determining the position of a probe tip. An evanescent electromagnetic field is generated extending beyond an interface boundary between a first medium, having a first refractive index, and a second medium, having a second refractive index which is greater than the first refractive index, the interface boundary extending in a plane. A probe tip is positioned in the evanescent field in the first medium thereby causing propagating electromagnetic radiation to be produced as a result of the disruption of the evanescent field by the probe tip, and at least a portion of the propagating electromagnetic radiation is collected. The spatial intensity distribution of the collected radiation is detected with respect to an image plane. An at least one dimensional position of the probe tip in a probe tip plane is determined from the detected spatial intensity distribution, the probe tip plane being a plane which contains the probe tip and which is substantially parallel to the plane of the interface boundary.

  • Patent number: 7962966
    Abstract: A scanning probe microscope and method for using the same are disclosed. The Scanning probe microscope includes a probe mount for connecting a cantilever arm and a probe signal generator. The probe position signal generator generates a position signal indicative of a position of the probe relative to one end of the cantilever arm. The probe position signal generator includes a first light source that directs a light beam at a first reflector positioned on the cantilever arm and a detector that detects a position of the light beam after the light beam has been reflected from the first reflector. A second reflector reflects the light beam after the light beam is reflected from the first reflector and before the light beam enters the detector, the second reflector passing light from a second light source that illuminates the sample.

  • Patent number: RE46350
    Abstract: A method for sample examination in a dual-beam FIB calculates a first angle as a function of second, third and fourth angles defined by the geometry of the FIB and the tilt of the specimen stage. A fifth angle is calculated as a function of the stated angles, where the fifth angle is the angle between the long axis of an excised sample and the projection of the axis of the probe shaft onto the X-Y plane. The specimen stage is rotated by the calculated fifth angle, followed by attachment to the probe tip and lift-out. The sample may then be positioned perpendicular to the axis of the FIB electron beam for STEM analysis by rotation of the probe shaft through the first angle.
