    摘要: A process for the fabrication of an inertial sensor with failure threshold includes the step of forming, on top of a substrate of a semiconductor wafer, a sample element embedded in a sacrificial region, the sample element configured to break under a preselected strain. The process further includes forming, on top of the sacrificial region, a body connected to the sample element and etching the sacrificial region so as to free the body and the sample element. The process may also include forming, on the substrate, additional sample elements connected to the body.

    摘要: A micromechanical structure for a MEMS three-axis capacitive accelerometer is provided with: a substrate; a single inertial mass having a main extension in a plane and arranged suspended above the substrate; and a frame element, elastically coupled to the inertial mass by coupling elastic elements and to anchorages, which are fixed with respect to the substrate by anchorage elastic elements. The coupling elastic elements and the anchorage elastic elements are configured so as to enable a first inertial movement of the inertial mass in response to a first external acceleration acting in a direction lying in the plane and also a second inertial movement of the inertial mass in response to a second external acceleration acting in a direction transverse to the plane.

    摘要: A microelectromechanical sensor includes: a supporting structure, having at least one first electrode and one second electrode, which form a capacitor; and a sensing mass made of non-conductive material, which is arranged so as to interact with an electric field associated to the capacitor and is movable with respect to the supporting structure according to a degree of freedom so that a relative position of the sensing mass with respect to the first electrode and to the second electrode is variable in response to external stresses. The sensing mass is made of a material selected in the group consisting of: intrinsic semiconductor materials, oxides of semiconductor materials, and nitrides of semiconductor materials.
