    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: Methods of forming field effect transistors include forming a first gate electrode on a semiconductor substrate and forming insulating spacers on sidewalls of the first gate electrode. At least a portion of the first gate electrode is then removed from between the insulating spacers to thereby expose inner sidewalls of the insulating spacers. Threshold-voltage adjusting impurities are then implanted into the semiconductor substrate, using the insulating spacers as an implant mask. These threshold-voltage adjusting impurities are selected from a group consisting of alkali metals from Group 1 of the periodic chart and halogens from Group 17 of the periodic chart. A second gate electrode is then formed between the inner sidewalls of the insulating spacers.
