    Abstract: An integrated circuit device including a substrate; a fin-type active region protruding from the substrate; a gate line intersecting the fin-type active region and covering a top surface and side walls thereof; a gate insulating capping layer covering the gate line; source/drain regions at sides of the gate line on the fin-type active region; first conductive plugs connected to the source/drain regions; a hard mask layer covering the first conductive plugs; and a second conductive plug between the first conductive plugs, the second conductive plug connected to the gate line by passing through the gate insulating capping layer and having a top surface higher than the top surface of each first conductive plug, wherein the hard mask layer protrudes from the first conductive plugs and toward the second conductive plug so that a portion of the hard mask layer overhangs from an edge of the first conductive plugs.

    Abstract: A semiconductor device includes a fin-type active region; a gate dielectric layer covering an upper surface and opposite lateral surfaces of the fin-type active region; and a gate line extending on the gate dielectric layer to cover the upper surface and opposite lateral surfaces of the fin-type active region and to cross the fin-type active region. The gate line includes an aluminum (Al) doped metal-containing layer extending to cover the upper surface and opposite lateral surfaces of the fin-type active region to a uniform thickness, and a gap-fill metal layer extending on the Al doped metal-containing layer over the fin-type active region. Related fabrication methods are also described.

    Abstract: A method of fabricating a semiconductor device having a dual gate allows for the gates to have a wide variety of threshold voltages. The method includes forming a gate insulation layer, a first capping layer, and a barrier layer in the foregoing sequence across a first region and a second region on a substrate, exposing the gate insulation layer on the first region by removing the first capping layer and the barrier layer from the first region, forming a second capping layer on the gate insulation layer in the first region and on the barrier layer in the second region, and thermally processing the substrate on which the second capping layer is formed. The thermal processing causes material of the second capping layer to spread into the gate insulation layer in the first region and material of the first capping layer to spread into the gate insulation layer in the second region. Thus, devices having different threshold voltages can be formed in the first and second regions.
