Abstract
A semiconductor device includes a magnetic tunneling junction (MTJ) on a substrate, a first spin orbit torque (SOT) layer on the MTJ, a passivation layer around the MTJ, and a second SOT layer on the first SOT layer and the passivation layer. Preferably, a top surface of the passivation layer is lower than a top surface of the first SOT layer.
