Abstract:
A magnetic shielding package of a non-volatile magnetic memory element, including: a soft magnetic material support plate 12; a first insulating material layer 13 formed on the support plate; a non-volatile magnetic memory element 11 fixed on the first insulating material layer; a second insulating material layer 14 that encapsulates the memory element and the periphery thereof; in the second insulating material layer, a wiring layer 15, a soft magnetic layer 15b or 25 and a conductive portion 16 connecting an electrode of the circuit surface of the memory element and the wiring layer; and a magnetic shield part 17 containing a soft magnetic material arranged like a wall at a distance from a side surface of the memory element so as to surround the memory element side surface partially or entirely, the magnetic shield part being magnetically connected to the soft magnetic layer.
