Abstract:
1. A method of manufacturing a magnetic memory, comprising: forming a stack film on a substrate, the stack film comprising: a first magnetic layer; an insulating layer formed on the first magnetic layer; and a second magnetic layer formed on the insulating layer; forming a conductive layer on the stack film; performing a patterning of an area that is not covered by the conductive layer; and performing an implantation of an impurity into the area after the patterning, wherein the first magnetic layer has a size of a magnetically- and electrically-active area smaller than a size of a magnetically- and electrically-active area of the second magnetic layer in a first direction perpendicular to a second direction in which the first magnetic layer, the insulating layer and the second magnetic layer are stacked, after the implantation.
