Abstract
An integrated circuit device includes a fin-type active region disposed on a substrate and extending in a first horizontal direction, a gate line disposed on the fin-type active region and extending in a second horizontal direction intersecting the first horizontal direction, the gate line including, a connection protrusion portion including a protrusion top surface at a first vertical level from the substrate, and a main gate portion including a recess top surface extending in the second horizontal direction from the connection protrusion portion, the recess top surface being at a second vertical level lower than the first vertical level, a gate contact disposed on the gate line and connected to the connection protrusion portion, a source/drain region disposed on the fin-type active region and disposed adjacent to the gate line, and a source/drain contact disposed on the source/drain region.
