Patent ID: 6982446

Claim:
A nonvolatile magnetic memory device comprising; (a) a transistor for selection, formed in a semiconductor substrate, (b) a first insulating interlayer covering the transistor for selection, (c) a first connecting hole formed in a first opening portion formed through the first insulating interlayer, and connected to the transistor for selection, (d) a first wiring being formed on the first insulating interlayer and extending in a first direction, (e) a second insulating interlayer covering the first insulating interlayer and the first wiring, (f) a tunnel magnetoresistance device being formed on the second insulating interlayer and comprising a tunnel barrier and two ferromagnetic layers, said tunnel barrier being sandwiched between said two ferromagnetic layers, one of the ferromagnetic layers including an anti-ferromagnetic layer and a pinned magnetic layer, (g) a third insulating interlayer covering the tunnel magnetoresistance device and the second insulating interlayer, (h) a second wiring being formed on the third insulating interlayer, being electrically connected to one end of the tunnel magnetoresistance device and extending in a second direction different from the first direction, and (i) a second connecting hole formed in a second opening portion formed through the second insulating interlayer, and connected to the first connecting hole, in which an end face of an extending portion of the anti-ferromagnetic layer but not the pinned magnetic layer is in contact with the second connecting hole.
