摘要： A bi-dimensional position sensor that can be advantageously used in the turn system controlled from the steering wheel of a vehicle. The sensor includes a permanent magnet fixed to a control lever so as to move in a plane along first and second directions and to rotate about a third direction orthogonal to the preceding ones. The permanent magnet is movable with respect to an integrated device including a first group of sensor elements arranged spaced along the first direction, a second group of sensor elements arranged spaced along the second direction and a third group of sensor elements detecting the angular position of the permanent magnet. Electronics integrated with the sensor elements generate a code associated with each position which the permanent magnet may assume and generate a control signal corresponding to the desired function.

摘要： An electrostatic cleaning structure of a hard disk driver is formed by a plurality of concentric conductive regions to which biasing pulse trains are supplied. Each biased conductive region generates an electric field attracting any dielectric particle. The pulse trains supplied to immediately adjacent conductive regions are phase-shifted by a predetermined time and in a direction linked to a desired direction of removal for the electrostatic particles. Voltage pulses sent to each conductive region are delayed with respect to voltage pulses sent to an immediately preceding conductive region in the direction of desired removal, and are advanced with respect the voltage pulses sent to an immediately successive conductive region.

摘要： The integrated inductor comprises a coil of metal which is formed in the second metal level. The coil is supported by a bracket extending above spaced from a semiconductor material body by an air gap obtained by removing a sacrificial region formed in the first metal level. The bracket is carried by the semiconductor material body through support regions which are arranged peripherally on the bracket and are separated from one another by through apertures which are connected to the air gap. A thick oxide region extends above the semiconductor material body, below the air gap, to reduce the capacitive coupling between the inductor and the semiconductor material body. The inductor thus has a high quality factor, and is produced by a process compatible with present microelectronics processes.

摘要： A movable mass forming a seismic mass is formed starting from an epitaxial layer and is covered by a weighting region of tungsten which has high density. To manufacture the mass, buried conductive regions are formed in the substrate. Then, at the same time, a sacrificial region is formed in the zone where the movable mass is to be formed and oxide insulating regions are formed on the buried conductive regions so as to partially cover them. An epitaxial layer is then grown, using a nucleus region. A tungsten layer is deposited and defined and, using a silicon carbide layer as mask, the suspended structure is defined. Finally, the sacrificial region is removed, forming an air gap.

摘要： The method is intended for manufacturing a microintegrated structure, typically a microactuator for a hard-disk drive unit and includes the steps of: forming interconnection regions in a substrate of semiconductor material; forming a monocrystalline epitaxial region; forming lower sinker regions in the monocrystalline epitaxial region and in direct contact with the interconnection regions; forming insulating material regions on a structure portion of the monocrystalline epitaxial region; growing a pseudo-epitaxial region formed by a polycrystalline portion above the structure portion of the monocrystalline epitaxial region and elsewhere a monocrystalline portion; and forming upper sinker regions in the polycrystalline portion of the pseudo-epitaxial region and in direct contact with the lower sinker regions. In this way no PN junctions are present inside the polycrystalline portion of the pseudo-epitaxial region and the structure has a high breakdown voltage.
