    Abstract: Disclosed is a semiconductor device comprising a substrate, a contact structure that penetrates the substrate, a bottom electrode on the substrate and connected to the contact structure, a dielectric layer that covers the bottom electrode, and a top electrode on the bottom electrode. The dielectric layer separates the top electrode from the bottom electrode. The contact structure includes a lower conductive pattern and an upper conductive pattern on the lower conductive pattern. The upper conductive pattern includes a nitride of a first metal implanted with a dopant.

    Abstract: A semiconductor device includes a capacitor including a lower electrode an upper electrode, and a dielectric layer between the lower electrode and the upper electrode. The lower electrode includes ABO3 where ‘A’ is a first metal element and ‘B’ is a second metal element having a work function greater than that of the first metal element. The dielectric layer includes CDO3 where ‘C’ is a third metal element and ‘D’ is a fourth metal element. The lower electrode includes a first layer and a second layer which are alternately and repeatedly stacked. The first layer includes the first metal element and oxygen. The second layer includes the second metal element and oxygen. The dielectric layer is in contact with the lower electrode at a first contact surface the first contact surface corresponding to the second layer.

    Abstract: A method of manufacturing a semiconductor device includes forming a lower metal layer, forming an interfacial oxide film on the lower metal layer, providing a metal precursor on the interfacial oxide film at a first pressure to adsorb the metal precursor into the interfacial oxide film, performing a first purge process at a second pressure to remove the unadsorbed metal precursor, the second pressure lower than the first pressure, providing an oxidizing gas at the first pressure to react with the adsorbed metal precursor, performing a second purge process at the second pressure to remove the unreacted oxidizing gas and form a dielectric film, and forming an upper metal layer on the dielectric film.
