Patent ID: 8779410

Claim:
A method of manufacturing a resistance change memory, the memory comprising resistance change elements, vias and sidewall insulating layers, the elements and the vias provided alternately in a first direction and a second direction orthogonal to the first direction, and the sidewall insulating layers provided on sidewalls of the elements, wherein the elements are provided in a lattice pattern having a constant pitch, a thickness of each of the sidewall insulating layers in a direction orthogonal to the sidewalls has at least a value for contacting the sidewall insulating layers to each other to form holes between the sidewall insulating layers, and the vias are provided in the holes respectively, and each of the resistance change elements is a magnetoresistive element including magnetic layers, the method comprising: forming the elements; forming an insulating material covering the elements; forming the holes in a self-alignment when the sidewall insulating layers is formed by etching back the insulating material; and forming the vias in the holes respectively.
