Microstructure provided with a magnetic antenna or a magnetic detection element

摘要

A microstructure comprises a semiconductor substrate (2) having an integrated electronic circuit and a magnetic antenna or a magnetic detecting device connected to the electronic circuit and comprising a winding (4) made of a conductor wire (6). This winding comprises a first part (8) arranged on the side of a top face (10) of the substrate, and a second part (9) on the side of the interior face of this substrate. The two parts are electrically connected by a first aperture (14) made in the substrate between the two faces.
