    摘要: Provided is a capacitor of a semiconductor device and a method of fabricating the same. In one embodiment, the capacitor includes a lower electrode formed on a semiconductor substrate; a dielectric layer formed on the lower electrode; and an upper electrode that is formed on the dielectric layer. The upper electrode includes a first conductive layer, a second conductive layer, and a third conductive layer stacked sequentially. The first conductive layer comprises a metal layer, a conductive metal oxide layer, a conductive metal nitride layer, or a conductive metal oxynitride layer. The second conductive layer comprises a doped polysilicon germanium layer. The third conductive layer comprises a material having a lower resistance than that of the second conductive layer.

    摘要: An electronic device may include a substrate, an oxide dielectric layer on the substrate, an interface layer on the oxide dielectric layer, and an electrode on the interface layer. The oxide dielectric layer may include an aluminum oxide layer between first and second zirconium oxide layers. The interface layer may have a first formation enthalpy, and the oxide dielectric layer may be between the substrate and the interface layer. The electrode may have a second formation enthalpy higher than the first formation enthalpy, and the interface layer may be between the oxide dielectric layer and the electrode.
