Abstract
A semiconductor memory device includes a substrate having a conductor region thereon, an interlayer dielectric layer on the substrate, and a conductive via electrically connected to the conductor region. The conductive via has a lower portion embedded in the interlayer dielectric layer and an upper portion protruding from a top surface of the interlayer dielectric layer. The upper portion has a rounded top surface. A storage structure conformally covers the rounded top surface.
