Abstract
A semiconductor device includes a lower electrode of a capacitor, a dielectric layer disposed on the lower electrode, and an upper electrode of the capacitor disposed on the dielectric layer. The upper electrode includes a doped poly-SiGelayer. An interlayer insulating layer is disposed on the doped poly-SiGelayer and has a contact hole partially exposing the doped poly-SiGelayer. A metal contact plug is in the contact hole and an interconnection layer is disposed on the interlayer insulating layer and connected to the metal contact plug. Related interconnection structures and fabrication methods are also disclosed.
