Patent ID: 7041603

Claim:
A method for producing a magnetic memory device, the method comprising: forming a magnetoresistive effect element; forming a first insulating film so as to cover the magnetoresistive effect element; forming a coating film so as to cover the first insulating film; exposing a top face of the magnetoresistive effect element; forming an upper writing line above the magnetoresistive effect element; exposing the first insulating film on a side portion of the magnetoresistive effect element by removing a part or all of the coating film; and forming a yoke structural member, after forming the upper writing line and after exposing the first insulating film, so as to cover at least a side portion of the upper writing line and the side portion of the magnetoresistive effect element to sandwich the exposed first insulating film between the yoke structural member and the side portion of the magnetoresistive effect element.
