Abstract:
1. A semiconductor device comprising: a magnetic tunnel junction (MTJ) storage element disposed in a common interlayer metal dielectric (IMD) layer with a logic element; a reduced thickness metal wire in the common IMD layer coupled to the MTJ storage element that is smaller in thickness then a corresponding metal wire of the logic element; a top cap layer separating a top IMD layer from the common IMD layer; a bottom cap layer separating a bottom IMD layer from the common IMD layer; a bottom electrode and a top electrode coupled to the MTJ storage element; a first metal wire in the bottom IMD layer coupled to the bottom electrode; and a second metal wire in the common IMD layer coupled to the top electrode, wherein the second metal wire is the reduced thickness metal wire.
