Abstract: A semiconductor device includes: a substrate; a transduction microstructure integrated in the substrate; a cap joined to the substrate and having a first face adjacent to the substrate and a second, outer, face; and a channel extending through the cap from the second face to the first face and communicating with the transduction microstructure. A protective membrane made of porous polycrystalline silicon permeable to aeriform substances is set across the channel.

Abstract: A method of manufacturing a magnetic-field sensor includes forming an insulating layer on a first surface of a substrate. First and second magnetoresistors are formed at different above the first surface of the substrate and are spaced apart from the first surface by different distances. The first and second magnetoresistors have respective main axes of magnetization transverse to one another, and respective secondary axes of magnetization transverse to one another. The method further includes forming a first magnetic-field generator configured to generate a first magnetic field having field lines along the main axis of magnetization of the first magnetoresistor, and forming a second magnetic-field generator configured to generate a second magnetic field having field lines along the main axis of magnetization of the second magnetoresistor.

Abstract: An electrostatically actuated oscillating structure includes a first stator subregion, a second stator subregion, a first rotor subregion and a second rotor subregion. Torsional elastic elements mounted to the first and second rotor subregions define an axis of rotation. A mobile element is coupled to the torsional elastic elements. The stator subregions are electrostatically coupled to respective regions of actuation on the mobile element. The stator subregions exhibit an element of structural asymmetry such that the electrostatic coupling surface between the first stator subregion and the first actuation region differs from the electrostatic coupling surface between the second stator subregion and the second actuation region.

Abstract: A semiconductor integrated device is provided with: a die having a body of semiconductor material with a front surface, and an active area arranged at the front surface; and a package having a support element carrying the die at a back surface of the body, and a coating material covering the die. The body includes a mechanical decoupling region, which mechanically decouples the active area from mechanical stresses induced by the package; the mechanical decoupling region is a trench arrangement within the body, which releases the active area from an external frame of the body, designed to absorb the mechanical stresses induced by the package.
