    摘要: Die vorliegende Erfindung betrifft das Gebiet des sogenannten Nanoprobing und adressiert insbesondere Probleme im Zusammenhang mit Einbau und Austausch von Probernadeln, die beim Nanoprobing genutzt werden sollen. Um eine Lösung vorzustellen, die es ermöglicht, die exakte Position der Nadeln zueinander zu bestimmen, wird ein Nanoprober mit einem ersten Manipulator, der dazu ausgestaltet ist, eine erste Probernadel mit einer ersten Nadelspitze im Raum zu bewegen, wobei diese Bewegung durch ein erstes Koordinatensystem beschreibbar ist, einem zweiten Manipulator, der dazu ausgestaltet ist, eine zweite Probernadel mit einer zweiten Nadelspitze im Raum zu bewegen, wobei diese Bewegung durch ein zweites Koordinatensystem beschreibbar ist, und einem Referenzobjekt vorgeschlagen, dessen Oberfläche räumlich so ausgestaltet ist, dass durch Bestimmung einer vorbestimmten Anzahl von Messpunkten für die erste Nadelspitze und die zweite Nadelspitze im ersten und zweiten Koordinatensystem das erste und das zweite Koordinatensystem zueinander in Beziehung setzbar sind, wobei sich ein Messpunkt durch eine Berührung einer Nadelspitze mit dem Referenzobjekt und/oder eine Annäherung der Nadelspitze an die Oberfläche des Referenzobjekts auf weniger als einen vordefinierten Abstand ergibt.

    摘要: Methods of measuring displacement of a movable mass in a microelectromechanical system (MEMS) include driving the mass against two displacement-stopping surfaces and measuring corresponding differential capacitances of sensing capacitors such as combs. A MEMS device having displacement-stopping surfaces is described. Such a MEMS device can be used in a method of measuring properties of an atomic force microscope (AFM) having a cantilever and a deflection sensor, or in a temperature sensor having a displacement-sensing unit for sensing a movable mass permitted to vibrate along a displacement axis. A motion-measuring device can include pairs of accelerometers and gyroscopes driven 90° out of phase.

    摘要: A method is presented for calibrating a cantilever, such as a scanning probe microscope cantilever (10) (SPM cantilever). The cantilever to be calibrated comprises at least a first and a second layer (14, 16) having a mutually different thermal expansion coefficient, the method comprising the steps of
    - controllably causing (S1) a temperature distribution along the cantilever,
    - measuring (S2) a spatial state of the cantilever,
    - computing (S3) a mechanical property from the observed spatial state caused by controllably changing the temperature.
    Also a calibration arrangement and a scanning probe microscope provided with the calibration arrangement are presented.

    摘要: This document relates to a method of tuning a scanning probe microscopy system and system therefore. The system comprising a sample carrier and a probe with a probe tip, and is configured for positioning the probe tip relative to a sample. The system further includes a transducer, a sensor for sensing probe tip vibrations, and a controller. The method comprises: a) applying an acoustic vibration signal comprising a first frequency and a second frequency to the sample; b) at a first position of the probe tip, controlling the transducer to sweep the first frequency across a first frequency range, and obtaining a first probe tip sensor signal; c) at a second position of the probe tip, controlling the transducer to sweep the first frequency across at least said first frequency range, and obtaining a second probe tip sensor signal; d) analyzing the first and second sensor signal to obtain a difference characteristic dependent on the first frequency, and selecting a first frequency value for which the difference characteristic exceeds a threshold for tuning 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.
