Abstract: An integrated circuit device includes an integrated circuit substrate and a first gate pattern on the substrate. A non-conductive barrier layer pattern is on the first gate pattern. The barrier layer pattern has openings at selected locations therein extending to the first gate pattern. A second gate pattern is on the barrier layer pattern and extends into the opening in the barrier layer pattern to electrically connect the second gate pattern to the first gate pattern.

Abstract: A semiconductor device and method of fabricating the same reduce the likelihood of the occurrence of electrical defects. The device includes a first interlayer insulating film on a semiconductor substrate; a contact pad spacer on the first interlayer insulating film; and a contact pad in the first interlayer insulating film and the contact pad spacer. The cross-sectional area of an upper portion of the contact pad in the contact pad spacer in a direction horizontal to the substrate is equal to or less than a cross-sectional area of an intermediate portion at an interface between the contact pad spacer and the first interlayer insulating film in a direction horizontal to the substrate.

Abstract: A semiconductor device and fabrication method thereof protect an overgrown metal silicide layer from external damage. The semiconductor device includes: isolation regions formed on a substrate; source/drain regions in the substrate between the isolation regions; a first interlayer insulating film on the substrate, the isolation regions and the source/drain regions; contact pads vertically penetrating the first interlayer insulating film and electrically connected to the source/drain regions; a second interlayer insulating film on the first interlayer insulating film and the contact pads; a metal silicide region selectively formed on the contact pads at a vertical position that is lower than an upper surface of the first interlayer insulating film; and a contact plug vertically penetrating the second interlayer insulating film and electrically connected to the metal silicide region.

Abstract: A transistor structure and a method of forming the same prevent a boundary face of first and second gate electrodes from being oxidized in a subsequent oxidation process, by forming an oxidation inhibition layer in the boundary face. A gate insulation layer is formed on a semiconductor substrate, and a gate stack is obtained by a sequential accumulation of first and second gate electrodes and a capping layer on the gate insulation layer. An oxidation inhibition layer is formed in a sidewall portion of the gate stack, and the oxidation inhibition layer covers a boundary face of the first and second gate electrodes. Source/drain regions are opposite to the gate stack.
