Abstract
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.
