Abstract
A semiconductor device includes an active region between portions of a device isolation layer on a substrate, a self-aligned pad layer on a first region of the active region, a bit line that is electrically connected to a second region of the active region, and a contact structure on a side surface of the bit line and electrically connected to the self-aligned pad layer. The self-aligned pad layer includes a pad protrusion that extends along an upper portion of a side surface of the first region of the active region, and a side of the self-aligned pad layer is in contact with the device isolation layer.
