Abstract
A semiconductor device includes a substrate insulating layer; a gate structure extending in one direction on the substrate insulating layer; a source/drain region outside of the gate structure; and a backside contact plug below the source/drain region to have a second central axis offset from a first central axis of the source/drain region in a horizontal direction, and connected to the source/drain region, wherein the source/drain region includes a first epitaxial layer including a non-silicon element in a first concentration, and a second epitaxial layer on the first epitaxial layer and including a non-silicon element in a second concentration, higher than the first concentration, and at least a portion of an upper surface of the backside contact plug is in contact with the second epitaxial layer.
