Semiconductor devices including spin-orbit torque line and contact plug

Abstract

A semiconductor device includes first and second contact plugs in an insulating layer that is on a substrate, the first and second contact plugs spaced apart from each other. A spin-orbit torque (SOT) line on the insulating layer and overlapping the first and second contact plug is provided. A magnetic tunnel junction (MTJ) is on the SOT line. An upper electrode is on the MTJ. Each of the first and second contact plugs includes a recess region adjacent the SOT line. A sidewall of the recess region is substantially coplanar with a side surface of the SOT line and a side surface of the MTJ.
