Abstract: A method of fabricating a device including a two-dimensional (2D) material includes forming a transition metal oxide pattern on a substrate and forming a transition metal dichalcogenide layer on a top surface and a side surface of a residual portion of the transition metal oxide pattern. The forming the transition metal dichalcogenide layer may include replacing a surface portion of the transition metal oxide pattern with the transition metal dichalcogenide layer. The transition metal dichalcogenide layer includes at least one atomic layer that is substantially parallel to a surface of the residual portion of the transition metal oxide pattern.

Abstract: A method of fabricating a semiconductor device using a recess channel array is disclosed. A substrate is provided having a first region and a second region, including a first transistor in the first region including a first gate electrode partially filling a trench, and source and drain regions that are formed at both sides of the trench, and covered by a first insulating layer. A first conductive layer is formed on the substrate. A contact hole through which the drain region is exposed is formed by patterning the first conductive layer and the first insulating layer. A contact plug is formed that fills the contact hole. A bit line is formed that is electrically connected to the drain region through the contact plug, and simultaneously a second gate electrode is formed in the second region by patterning the first conductive layer.
