    摘要: Methods and apparatus are provided for forming thin films for semiconductor devices, which enable supplying and removing reactants containing constituent elements of a thin film to be formed, by preheating and supplying a process gas and a purging gas at a predetermined temperature in forming the thin film on a substrate. For example, a method for forming a thin film includes supplying a first reactant to a chamber to chemically adsorb the first reactant onto a substrate, the first reactant being bubbled by a first gas that is preheated, purging the chamber to remove residues on the substrate having the first reactant chemically adsorbed, and forming the thin film by a means of chemical displacement by supplying a second reactant to the chamber to chemically adsorb the second reactant onto the substrate.

    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.
