Abstract
A semiconductor device includes a fin-type active region that protrudes from a substrate and extends in a first direction, a plurality of channel layers on the fin-type active region that are spaced apart from each other in a second direction that is perpendicular to an upper surface of the substrate, a gate structure that intersects the fin-type active region, extends in the second direction, and surrounds each of the plurality of channel layers in a third direction, fence spacers on side surfaces of the fin-type active region in the second direction on sides of the gate structure and extending in the second direction, and a source/drain region between the fence spacers on the fin-type active region at sides of the gate structure, connected to each of the plurality of channel layers, and having voids in side surfaces adjacent the fence spacers.
