Abstract
A memory device includes a magnetic tunnel junction pillar located between, and electrically connected to, a bottom electrode and a top electrode. The magnetic tunnel junction pillar is composed of a plurality of device layers vertically stacked above the bottom electrode. Each of the plurality of device layers, the top electrode, and the bottom electrode is formed at a first bevel angle. A bottommost portion of each of the plurality of device layers in the magnetic tunnel junction pillar has a width that is greater than a width of a topmost portion of each preceding device layer. An encapsulation layer is disposed along opposite sidewalls of the top electrode, opposite sidewalls of the bottom electrode, and opposite sidewalls of each of the plurality of device layers.
