Abstract

A semiconductor device includes a substrate, a gate electrode on the substrate, a gate spacer on a sidewall of the gate electrode, an active pattern penetrating the gate electrode and the gate spacer, and an epitaxial pattern contacting the active pattern and the gate spacer. The gate electrode extends in a first direction. The gate spacer includes a semiconductor material layer. The active pattern extends in a second direction crossing the first direction.
