A semiconductor device and a method for fabricating the semiconductor device. The method comprises: forming a stack structure including a lower level sacrificial layer over a semiconductor substrate; forming a slit penetrating through the stack structure and exposing the lower level sacrificial layer; forming a spacer on a sidewall of the slit; forming horizontal recesses by removing the lower level sacrificial layer; forming a conductive material in each of the horizontal recesses; etching the conductive material to form source channel contacts filling the horizontal recesses, respectively, and to form a separation groove between the conductive patterns; and forming an etch barrier material filling the separation groove.
