摘要： Provided are methods for fabricating semiconductor devices. The methods for fabricating the semiconductor devices may include forming a first interlayer insulation film including a trench on a substrate, forming a high-k layer along an inner sidewall and a bottom surface of the trench, forming a first work function control film including impurities along the high-k layer, removing the impurities from the first work function control film to reduce surface resistance of the first work function control film by about 30% to about 60% and forming a gate metal in the trench.

摘要： A semiconductor device includes a substrate and first and second gate electrodes on the substrate. The first gate electrode includes a first gate insulation film having a bottom portion on the substrate and sidewall portions extending from the bottom portion and away from the substrate defining a first trench having a first width and a first functional film filling the first trench. The second gate electrode includes a second gate insulation film having a bottom portion on the substrate and sidewall portions extending from the bottom portion defining a second trench having a second width different from the first width, a second functional film conforming to the second gate insulation film in the second trench and defining a third trench, and a metal region in the third trench. The first width may be less than the second width.
