Abstract:
A method is presented for establishing a top contact to a magnetic tunnel junction (MTJ) device, the method including selectively etching, via a first etching process, an oxide layer to expose a top surface of a nitride layer of a dummy fill shape and selectively etching, via a second etching process, a top portion of the nitride layer of the dummy fill shape to expose a top surface thereof. The method further includes selectively etching, via the second etching process, the oxide layer to expose a top surface of a nitride layer of the MTJ device, and selectively etching, via the first etching process, a top portion of the nitride layer of the MTJ device to expose a top surface thereof such that a height of the MTJ device is approximately equal to a height of the dummy fill shape.

Claim (Index 20):
The structure of  claim 19 , wherein a dummy fill shape is formed adjacent the plurality of MTJ devices.
