An integrated circuit (IC) device including a fin-type active region on a substrate and a gate line on the fin-type active and having a first uppermost surface at a first vertical level, an insulating spacer covering a sidewall of the gate line and having a second uppermost surface at the first vertical level, and an insulating guide film covering the second uppermost surface of the insulating spacer may be provided. The gate line may include a multilayered conductive film structure that includes a plurality of conductive patterns and have a top surface defined by the conductive patterns, which includes at least first and second conductive patterns including different materials from each other and a unified conductive pattern that is in contact with a top surface of each of the conductive patterns and has a top surface that defines the first uppermost surface.

Integrated circuit device including insulating guide film between adjacent conductive patterns

A semiconductor device includes a contact structure connected to an active region. A first insulating layer is disposed on a barrier dielectric layer and has a first hole connected to the contact structure. A second insulating layer is disposed on the first insulating layer and has a trench connected to the first hole. The second insulating layer has an extended portion along a side wall of the first hole. A width of the first hole less the space occupied by the extended portion is defined as a second hole. A wiring structure including a conductive material is connected to the contact structure. A conductive barrier is disposed between the conductive material and the first and second insulating layers. An etch stop layer is disposed between the first and second insulating layers and between the extended portion of the second insulating layer and a side wall of the first hole.
