    摘要: Semiconductor devices and methods of manufacturing semiconductor devices. A semiconductor device includes a metal gate electrode stacked on a semiconductor substrate with a gate insulation layer disposed therebetween, spacer structures disposed on the semiconductor substrate at both sides of the metal gate electrode, source/drain regions formed in the semiconductor substrate at the both sides of the metal gate electrode, and an etch stop pattern including a bottom portion covering the source/drain regions and a sidewall portion extended from the bottom portion to cover a portion of sidewalls of the spacer structures, in which an upper surface of the sidewall portion of the etch stop pattern is positioned under an upper surface of the metal gate electrode.

    摘要: A method of fabricating semiconductor devices having metal gate electrodes includes forming an insulating layer on a semiconductor substrate having a first region and a second region. The insulating layer is formed to include an interlayer insulating layer and a gate insulation layer. The interlayer insulating layer has first and second grooves respectively disposed in the first and second regions, and the gate insulation layer covers at least bottom surfaces of the first and second grooves. A laminated metal layer is formed on the substrate having the insulating layer. A planarization layer having non-photo sensitivity is formed on the laminated metal layer. The planarization layer in the first region is selectively removed using a dry etching process to expose the laminated metal layer in the first region and to form a planarization layer pattern covering the laminated metal layer in the second region.

    摘要: A semiconductor device includes an active pattern protruding from a substrate, gate structures crossing over the active pattern, gate spacers on sidewalls of the gate structures, a source/drain region n the active pattern between the gate structures, and a source/drain contact on and connected to the source/drain region. The source/drain contact includes a first portion between the gate structures and being in contact with the gate spacers, a second portion on the first portion and not being in contact with the gate spacers, and a third portion on the second portion. A first boundary between the second and third portions is at the substantially same height as a top surface of the gate structure.

    摘要: Semiconductor devices may include a substrate, gate electrodes on the substrate, and source/drain regions at both sides of each of the gate electrodes. Each of the gate electrodes may include a gate insulating pattern on the substrate, a lower work-function electrode pattern that is on the gate insulating pattern and has a recessed upper surface, and an upper work-function electrode pattern that conformally extends on the recessed upper surface of the lower work-function electrode pattern. Topmost surfaces of the lower work-function electrode patterns may be disposed at an equal level, and the upper work-function electrode patterns may have different thicknesses from each other.
