    摘要: A method of forming a semiconductor device may include forming an interlayer insulating layer on a semiconductor substrate, and the interlayer insulating layer may have a contact hole therein exposing a portion of the semiconductor substrate. A single crystal semiconductor plug may be formed in the contact hole and on portions of the interlayer insulating layer adjacent the contact hole opposite the semiconductor substrate, and portions of the interlayer insulating layer opposite the semiconductor substrate may be free of the single crystal semiconductor plug. Portions of the single crystal semiconductor plug in the contact hole may be removed while maintaining portions of the single crystal semiconductor plug on portions of the interlayer insulating layer adjacent the contact hole as a single crystal semiconductor contact pattern. After removing portions of the single crystal semiconductor plug, a single crystal semiconductor layer may be formed on the interlayer insulating layer and on the single crystal semiconductor contact pattern. A second interlayer insulating layer may be formed on the single crystal semiconductor layer, and a common contact hole may be formed through the second interlayer insulating layer, through the single crystal semiconductor layer, and through the first interlayer insulating layer to expose a portion of semiconductor substrate. In addition, a conductive contact plug may be formed in the common contact hole in contact with the semiconductor substrate. Related devices are also discussed.

    摘要: Contacts having different characteristics may be created by forming a first silicide layer over a first device region of a substrate, and then forming a second silicide layer over a second device region while simultaneously further forming the first silicide layer. A first contact hole may be formed in a dielectric layer over a first device region of a substrate. A silicide layer may then be formed in the first contact hole. A second contact hole may be formed after the first contact hole and silicide layer is formed. A second silicidation may then be performed in the first and second contact holes.

    摘要: A method of fabricating a semiconductor device includes forming a preliminary gate pattern on a semiconductor substrate. The preliminary gate pattern includes a gate oxide pattern, a conductive pattern, and a sacrificial insulating pattern. The method further includes forming spacers on opposite sidewalls of the preliminary gate pattern, forming an interlayer dielectric pattern to expose the sacrificial insulating pattern, removing the sacrificial insulating pattern to form an opening to expose the conductive pattern, transforming the conductive pattern into a metal silicide layer and forming a metal barrier pattern along an inner profile of the opening and a metal conductive pattern to fill the opening including the metal barrier pattern. The metal silicide layer and the metal conductive pattern constitute a gate electrode.
