Abstract
A semiconductor device includes an active region on a semiconductor substrate. The active region is defined by a device isolation layer and includes gate-recesses. The semiconductor device further includes gate electrodes in the gate-recesses, a contact recess in the active region between the gate-recesses, a cell pad that covers at least a portion of the active region between the gate-recesses and that fills at least a portion of the contact recess, and a bit line electrically connected to the cell pad.
