Abstract:
The present disclosure describes a method utilizing an ion beam etch process, instead of a RIE etch process, to form magnetic tunnel junction (MTJ) structures. For example, the method includes forming MTJ structure layers on an interconnect layer, where the interconnect layer includes a first area and a second area. The method further includes depositing a mask layer over the MTJ structure layers in the first area and forming masking structures over the MTJ structure layers in the second area. The method also includes etching with an ion beam etch process, the MTJ structure layers between the masking structures to form MTJ structures over vias in the second area of the interconnect layer; and removing, with the ion beam etch process, the mask layer, the top electrode, the MTJ stack, and a portion of the bottom electrode in the first area of the interconnect layer.

Claim (Index 12):
The method of  claim 10 , further comprising:\n forming, over the second area of the substrate, an interlayer dielectric between the MTJ structures; and forming, over the first area of the substrate, another interlayer dielectric on the spacer layer.
