Abstract
A semiconductor structure may include a pyramidal magnetic tunnel junction on top of a bottom electrode, a tunnel layer on top and in electrical contact with the first magnetic layer, a second magnetic layer on top and in electrical contact with the tunnel layer, and a hard mask cap on top of the second magnetic layer. The pyramidal magnetic tunnel junction may have a first magnetic layer on top and in electrical contact with the bottom electrode. The semiconductor structure may include a first encapsulation spacer positioned along vertical sidewalls of the hard mask cap, a second encapsulation spacer positioned along vertical sidewalls of the second magnetic layer, a third encapsulation spacer positioned along vertical sidewalls of the tunnel layer, and a fourth encapsulation spacer positioned along vertical sidewalls of the first magnetic layer.
