  • Patent number: 11243151
    Abstract: The invention relates to a device for carrying out bending tests on panel-shaped or beam-shaped samples (1), in which two rotary drives are arranged at a distance from one another and a flange (3) is fastened to each of the drive shafts of the rotary drives, said drive shafts being oriented parallel to one another. At least two bar-shaped bending elements (2) oriented parallel to the axis of rotation of the drive shafts and arranged at a distance from the axis of rotation and at a distance from one another are provided on each of the flanges (3). A panel-shaped or beam-shaped sample (1) can be introduced between the two bar-shaped bending elements (2) on the two flanges (3). In the event of rotation of the rotary drives in opposite directions of rotation, bending forces are exerted on the sample (1) and each of the two rotary drives can be controlled individually and connected to an electronic open-loop or closed-loop control unit.

  • Patent number: 10151645
    Abstract: The invention relates to an arrangement and to a method for the synchronous determination of the shear modulus and of the Poisson's number on samples of elastically isotropic and anisotropic materials. In the arrangement, an indenter is movable in parallel with its longitudinal axis (A) in the direction of the surface of a sample such that a force action is exerted on the material by its tip. The force can be determined by a device for measuring this force and the indenter is additionally deflected in translation along at least one further axis. The longitudinal axis (A) of the indenter is aligned at an angle ?90° with respect to the surface of the sample and the indenter carries out an upward movement and a downward movement.

  • Patent number: 8056402
    Abstract: By forming an appropriate material layer, such as a metal-containing material, on a appropriate substrate and patterning the material layer to obtain a cantilever portion and a tip portion, a specifically designed nano-probe may be provided. In some illustrative aspects, additionally, a three-dimensional template structure may be provided prior to the deposition of the probe material, thereby enabling the definition of sophisticated tip portions on the basis of lithography, wherein, alternatively or additionally, other material removal processes with high spatial resolution, such as FIB techniques, may be used for defining nano-probes, which may be used for electric interaction, highly resolved temperature measurements and the like. Thus, sophisticated measurement techniques may be established for advanced thermal scanning, strain measurement techniques and the like, in which a thermal and/or electrical interaction with the surface under consideration is required.

  • Patent number: 8039395
    Abstract: An alloy forming dopant material is deposited prior to the formation of a copper line, for instance by incorporating the dopant material into the barrier layer, which is then driven into the vicinity of a weak interface by means of a heat treatment. As indicated by corresponding investigations, the dopant material is substantially transported to the weak interface through grain boundary regions rather than through the bulk copper material (copper grains), thereby enabling moderately high alloy concentrations in the vicinity of the interface while maintaining a relatively low overall concentration within the grains. The alloy at the interface reduces electromigration along the interface.

  • Patent number: 7441446
    Abstract: By digitizing the UFM signal without using a lock-in amplifier, substantially all of the information initially contained in the UFM output signal may be maintained and may then be used for further data processing. Consequently, any type of model or evaluation algorithm may be used without being restricted to a very narrow bandwidth, as is the case in lock-in based techniques. The digitizing is performed on a real-time basis, wherein a complete UFM curve is digitized and stored for each scan position. In this way, quantitative meaningful values for specific surface-related characteristics with a nanometer resolution may be obtained.

  • Patent number: 7311008
    Abstract: A semiconductor structure comprises a stress sensitive element. A property of the stress sensitive element is representative of a stress in the semiconductor structure. Additionally, the semiconductor structure may comprise an electrical element. The stress sensitive element and the electrical element comprise portions of a common layer structure. Analyzers may be adapted to determine a property of the stress sensitive element being representative of a stress in the semiconductor structure and a property of the electrical element. The property of the stress sensitive element may be determined and the manufacturing process may be modified based on the determined property of the stress sensitive element. The property of the electrical element may be related to the property of the stress sensitive element in order to investigate an influence of stress on the electrical element.

  • Patent number: 7183629
    Abstract: During the formation of a metallization layer of a semiconductor device, a cap layer is formed above a metal line and subsequently an implantation process is performed so as to modify the metal in the vicinity of the interface between the cap layer and the metal line. Consequently, an improved behavior in view of electromigration of the metal line may be obtained, thereby increasing device reliability.
