    摘要: A method for fabricating a semiconductor device comprises forming a gate insulation layer on a substrate including a first region and a second region, forming a first gate conductive layer and a capping layer on the first region and the second region and heat-treating the substrate, removing the capping layer from the first region and the second region, forming a second gate conductive layer on the first region and the second region, nitriding the second gate conductive layer, and forming a third gate conductive layer on the second region.

    摘要: A semiconductor device may include active fins spaced apart from each other by a recess therebetween, each of the active fins protruding from an upper surface of a substrate, an isolation structure including a liner on a lower surface and a sidewall of a lower portion of the recess and a blocking pattern on the liner, the blocking pattern filling a remaining portion of the lower portion of the recess and including a nitride, a carbide or polysilicon, a gate electrode structure on the active fins and the isolation structure, and a source/drain layer on a portion of each of the active fins adjacent to the gate electrode structure.
