INTEGRATED CIRCUIT DEVICE

An integrated circuit device includes: a first fin-type active region and a second fin-type active region that extend on a substrate in a straight line in a first horizontal direction and are adjacent to each other in the first horizontal direction; a fin isolation region arranged between the first fin-type active region and the second fin-type active region on the substrate and including a fin isolation insulation structure extending in a second horizontal direction perpendicular to the first horizontal direction; and a plurality of gate lines extending on the first fin-type active region in the second horizontal direction, wherein a first gate line that is closest to the fin isolation region from among the plurality of gate lines is inclined to be closer to a center of the fin isolation region in the first horizontal direction from a lowermost surface to an uppermost surface of the first gate line.
