Abstract: An integrated circuit (IC) device includes a fin-type active region extending in a first lateral direction on a device region of a substrate. A gate line extends in a second lateral direction on the fin-type active region. The second lateral direction intersects with the first lateral direction. A source/drain region is adjacent to one side of the gate line on the fin-type active region. A gate contact is on the gate line and connected to the gate line. A source/drain contact is on the source/drain region and includes a first segment facing the gate contact and a second segment integrally connected to the first segment. The second segment extends from the first segment in the second lateral direction. In the first lateral direction, a first distance from the first segment to the gate line is greater than a second distance from the second segment to the gate line.
