Patent number: 8707461Abstract: 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.Type: GrantFiled: October 18, 2012Date of Patent: April 22, 2014Assignee: FEI CompanyInventors: Arthur Reinout Hartong, Cornelis Sander Kooijman

Patent number: 8646111Abstract: 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.Type: GrantFiled: February 13, 2007Date of Patent: February 4, 2014Assignee: The Regents of the University of CaliforniaInventors: Kimberly L.

Patent number: 8051493Abstract: 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.Type: GrantFiled: April 9, 2008Date of Patent: November 1, 2011Assignee: The University of BristolInventors: Arturas Ulcinas, John D. Engledew, Michael L. Picco, John M. Miles, Massimo Antognozzi

Patent number: 7962966Abstract: 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.Type: GrantFiled: May 26, 2009Date of Patent: June 14, 2011Assignee: Agilent Technologies, Inc.Inventor: James Robert Massie

Patent number: 7888655Abstract: The invention relates to a transfer mechanism for transferring a specimen (2) from a first position in a first holder (40) to a second position in a second holder (10) and/or vice versa, each holder (10, 40) equipped to detachably hold the specimen, the transfer of the specimen between the holders taking place in a transfer position different from the second position, characterized in that when the specimen is transferred between the holders (10, 40) a mechanical guidance mechanism positions the holders with a mutual accuracy higher than the mutual accuracy in the second position, and said mechanical guidance mechanism not positioning at least one of the holders (10, 40) when the specimen is in the second position. The mechanical guidance mechanism may comprise extra parts (50). At least one of the holders (40) may be equipped to hold a multitude of specimens.Type: GrantFiled: July 25, 2007Date of Patent: February 15, 2011Assignee: FEI CompanyInventors: Erik Pieter van Gaasbeek, Pleun Dona, Gerbert Jeroen van de Water, Johannes Antonius Maria van den Oetelaar, Paul Johannes Leonardes Barends, Ian Johannes Bernardus van Hees

Patent number: RE46350Abstract: 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.Type: GrantFiled: April 22, 2014Date of Patent: March 28, 2017Assignee: Omniprobe, Inc.Inventors: Lyudmila Zaykova-Feldman, Thomas M.
