  • Sensor for magnetic fields with Laplace force
    Patent number: 9562789
    Abstract: A magnetic field sensor comprises a substrate and a moving part which is displaced when subjected to a Laplace force. There is a gauge for measuring the displacement of the moving part. There is a suspended lever that is rotationally displaced about an axis of rotation at right angles to the direction of displacement of the moving part. The lever is connected to the moving part to transmit displacement of the moving part to the lever to cause rotation of the lever about the axis of rotation. The lever is also connected to a first part of the gauge. The sensor comprises a hinge that connects the lever to the substrate. The hinge allows the rotation of the lever about its axis of rotation and is rigid to allow for a lever arm effect. The second part of the gauge is fixed with no degree of freedom to the substrate.

  • Method and system for preparing a pattern to be printed on a plate or mask by electron beam lithography
    Patent number: 9542505
    Abstract: A method for preparing a pattern to be printed on a plate or mask by electron beam lithography comprising the following steps: modelling of the pattern by breaking down this pattern into a set of elementary geometric shapes intended to be printed individually in order to reproduce said pattern and, for each elementary geometric shape of the model; determination of an electrical charge dose to be applied to the electron beam during the individual printing of the elementary shape, this dose being chosen from a discrete set of doses including several non-zero predetermined doses recorded in memory. The set of elementary geometric shapes is a bidimensional paving of identical elementary geometric shapes covering the pattern to be printed. In addition, when the doses to be applied to the elementary geometric shapes are determined, a discretization error correction is made by dithering.
