An integrated circuit device includes a substrate including a fin active region extending in a first direction, a gate line intersecting the fin active region and extending in a second direction perpendicular to the first direction, a power line electrically connected to source/drain regions at sides of the gate line on the fin active region, a pair of dummy gate lines intersecting the fin active region and extending in the second direction, and a device separation structure electrically connected to the pair of dummy gate lines and including a lower dummy contact plug between the pair of dummy gate lines on the fin active region and electrically connected to the power line, and an upper dummy contact plug on the lower dummy contact plug and on the pair of dummy gate lines to electrically connect the lower dummy contact plug to the pair of dummy gate lines.
