Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A semiconductor device comprising:
a substrate including active regions that extend in a first direction;
a device isolation layer that defines the active regions in the substrate;
gate structures including gate electrode layers that extend in a second direction that intersect the active regions;
source/drain regions on the active regions on at least one sides of the gate structures;
contact plugs on the source/drain regions on the at least one sides of the gate structures;
contact insulating layers that contact the gate structures and that surround sidewalls of the contact plugs; and
a sidewall insulating layer having a first portion that extends along and parallel to an upper surface of the device isolation layer and a second portion that extends upward and parallel to a lower portion of an outer surface of the source/drain regions, when viewed in a cross-sectional view along the second direction.
