Abstract
Provided is a semiconductor device which includes: a substrate; a channel structure on the substrate; a source/drain pattern connected to the channel structure; a gate structure on the channel structure; an inner spacer structure comprising an inner spacer between the source/drain pattern and the gate structure, and an inner spacer residue connected to the inner spacer structure; and an inner isolation structure between the inner spacer residue and a bottom surface of the source/drain pattern.
