摘要： An integrated magnetoresistive device, where a substrate of semiconductor material is covered, on a first surface, by an insulating layer. A magnetoresistor of ferromagnetic material extends in the insulating layer and defines a sensitivity plane of the sensor. A concentrator of ferromagnetic material including at least one arm, extending in a transversal direction to the sensitivity plane and vertically offset to the magnetoresistor. In this way, magnetic flux lines directed perpendicularly to the sensitivity plane are concentrated and deflected so as to generate magnetic-field components directed in a parallel direction to the sensitivity plane.

摘要： An integrated magnetic sensor formed in a body including a substrate of semiconductor material, which integrates a Hall cell. A trench is formed in the body, for example, on the back of the substrate, and is delimited by lateral surface portions that extend in a direction transverse to the main face of the body. The trench has a depth in a direction perpendicular to the main face that is much greater than its width in a direction parallel to the main face of the body, between the lateral surface portions. A concentrator made of ferromagnetic material is formed within the trench and is constituted by two ferromagnetic regions, which are set at a distance apart from one another and extend along the lateral surface portions of the trench towards the first Hall cell.

摘要： The integrated magnetic sensor for detecting an external magnetic field, is formed by a body of semiconductor material having a surface; an insulating layer covering the body of semiconductor material; a magnetically sensitive region, for example a Hall cell, extending inside the body; and a concentrator of ferromagnetic material, extending on the Hall cell and having a planar portion extending parallel to the surface of the substrate on the insulating layer. The concentrator terminates with a tip protruding peripherally from, and transversely to, the planar portion toward the Hall cell. When the magnetically sensitive region is a sensing coil of a fluxgate sensor, it is formed on the substrate, embedded in the insulating layer, and the tip of the concentrator can reach as far as the sensing coil.
