Classification: CPC H | IPC H

Claim 10:
11. A semiconductor device comprising:
a substrate including an active region that extends in a first direction;
a gate structure that extends in a second direction that intersects the active region;
a source/drain region on the active region on at least one side of the gate structure;
a contact plug on the source/drain region on the at least one side of the gate structure;
a contact insulating layer on sidewalls of the contact plug;
a sidewall insulating layer having a first portion that extends in parallel to an upper surface of the substrate and a second portion that extends upward and in parallel to an outer surface of the source/drain region, when viewed in a cross-sectional view along the second direction; and
an interlayer insulating layer on the substrate,
wherein the contact insulating layer is between the interlayer insulating layer and the contact plug and between the gate structure and the contact plug, when viewed in a plan view.
