    摘要: A method of fabricating a semiconductor device includes forming an interlayer dielectric on a substrate, the interlayer dielectric including first and second openings respectively disposed in first and second regions formed separately in the substrate; fondling a first conductive layer filling the first and second openings; etching the first conductive layer such that a bottom surface of the first opening is exposed and a portion of the first conductive layer in the second opening remains; and forming a second conductive layer filling the first opening and a portion of the second opening.

    摘要: A method of fabricating a semiconductor device may include: preparing a substrate in which first and second regions are defined; forming an interlayer insulating film, which includes first and second trenches, on the substrate; forming a work function control film, which contains Al and N, along a top surface of the interlayer insulating film, side and bottom surfaces of the first trench, and side and bottom surfaces of the second trench; forming a mask pattern on the work function control film formed in the second region; injecting a work function control material into the work function control film formed in the first region to control a work function of the work function control film formed in the first region; removing the mask pattern; and forming a first metal gate electrode to fill the first trench and forming a second metal gate electrode to fill the second trench.
