Abstract:
A method of manufacturing an MRAM device including forming a first insulating interlayer and a lower electrode contact, the lower electrode contact extending through the first insulating interlayer; forming a lower electrode layer, a magnetic tunnel junction layer, an upper electrode layer, and a first hard mask layer on the first insulating interlayer and lower electrode contact; forming a second hard mask on the first hard mask layer; etching the first hard mask layer and upper electrode layer to form a first hard mask and upper electrode; forming a spacer on sidewalls of the upper electrode and hard masks; and etching the magnetic tunnel junction layer and the lower electrode layer to form a structure including a lower electrode and a magnetic tunnel junction pattern on the lower electrode contact, wherein a layer remains on the upper electrode after etching the magnetic tunnel junction layer and the lower electrode layer.

Claim (Index 9):
The method as claimed in  claim 7 , wherein etching the magnetic tunnel junction layer and the lower electrode layer using the first hard mask, the second hard mask, and the spacer as the etching mask includes removing the second hard mask such that the first hard mask remains on the upper electrode.
