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 12):
The method as claimed in  claim 1 , wherein etching the first hard mask layer and the upper electrode layer to form the first hard mask and the upper electrode, respectively, includes forming a plurality of upper electrodes, and\n wherein the method further comprises: forming a second capping layer on the spacer, the structure, the first insulating interlayer, and the at least one layer remaining on each of the plurality of upper electrodes; forming a second insulating interlayer on the second capping layer to fill a gap between the plurality of upper electrodes; and forming a via contact on each of the plurality of upper electrodes such that the via contact extends through the second insulating interlayer.
