Patent ID: 8455267

Claim:
A method comprising: forming a magnetic tunnel junction (MTJ) device on a structure that comprises a bottom cap layer and a bottom metal-filled trench having a normal axis, the magnetic tunnel junction device comprising a bottom electrode, magnetic tunnel junction layers, a magnetic tunnel junction seal layer, a top electrode, and a logic cap layer, the magnetic tunnel junction device having an MTJ axis that is offset from the normal axis; forming and planarizing an insulating layer above the logic cap layer; and performing a copper damascene process to open a top trench in the insulating layer, to open a top via to the top electrode, to open a logic via to metal in the bottom metal-filled trench, or to open the top via and the logic via, to deposit copper in the top trench and in the top via, in the logic via, or in the top via and in the logic via, and to perform a copper chemical mechanical planarization of the deposited copper.
