    摘要: Example embodiments of the present invention relates to methods of fabricating a semiconductor device. Other example embodiments of the present invention relate to methods of fabricating a semiconductor device using a metal nitride layer as a gate electrode. The methods may include providing a semiconductor substrate having a first region and a second region. A gate insulating layer, a metal nitride layer and/or an amorphous carbon layer may be sequentially formed on the substrate. The amorphous carbon layer may be selectively etched, forming an amorphous carbon mask covering the first region. The metal nitride layer, exposed by the amorphous carbon mask, may be etched, forming a preliminary metal nitride pattern. The amorphous carbon mask may be removed.

    摘要: In a semiconductor device having an enlarged contact area between a contact structure and a substrate, the substrate may include a first region on which a conductive structure is arranged and a second region defining the first region. The first region may include a multi-faced polyhedral recess of which at least one of the sidewalls is slanted with respect to a surface of the substrate. An insulation layer may be formed on the substrate to a thickness that is sufficient to cover the conductive structure. The insulation layer has a contact hole that may be communicated with the recess. The active region of the substrate is exposed through the contact hole. A conductive pattern is positioned in the recess and the contact hole. Accordingly, the contact resistance at the active region of the substrate may be kept to a relatively low value even though the gap distances and line width of pattern lines are reduced.
