Abstract:
Methods for MTJ patterning for a MTJ device are provided. For example, a method includes (a) providing an MTJ device comprising a substrate comprising a plurality of bottom electrodes, a MTJ layer disposed on the substrate, and a plurality of pillars disposed on the MTJ layer and over the plurality of bottom electrodes, wherein the plurality of pillars comprise a metal layer and a hard mask layer disposed on the metal layer, (b) conducting a first ion beam etching of the MTJ device; (c) rotating the MTJ device by 90 degrees in a clockwise or a counter clockwise direction about an axis perpendicular to a top surface of the MTJ device from a starting position; (d) conducting a second ion beam etching of the MTJ device; and (e) repeating steps (c) and (d).

Claim (Index 14):
The method of  claim 13 , wherein the fifth ion beam etching is carried out at a tilt angle relative to the top surface of the MTJ device of from about 10 to about 80 degrees, and an etch rate of from about 0.1 to about 10 A/s
