Methods for inducing compressive strain in channel region of a non-planar transistor and devices and systems formed by such methods. In one embodiment, a method can include forming trenches in a semiconductor body adjacent to gate structure spacers. The semiconductor body can be situated on a substrate and in a different plane relative to the substrate. The gate structure can be situated on the semiconductor body and the silicon fin and perpendicular to the semiconductor body. After formation of the semiconductor body and the gate structure on the substrate, a dielectric material can be conformally deposited on the substrate and etched to form spacers on the semiconductor body and the gate structure. The substrate can be patterned and etched to form trenches in the semiconductor body adjacent to the spacers on the gate structure. A strain material can be introduced into the trenches.
