Abstract
A method for fabricating a semiconductor device includes forming a stack structure including a horizontal recess over a substrate, forming a blocking layer lining the horizontal recess, forming an interface control layer including a dielectric barrier element and a conductive barrier element over the blocking layer, and forming a conductive layer over the interface control layer to fill the horizontal recess.
