    摘要: Capacitors include an integrated circuit (semiconductor) substrate and an interlayer dielectric disposed on the integrated circuit substrate and including a metal plug therein. A lower electrode is disposed on the interlayer dielectric and contacting the metal plug. The lower electrode includes a cavity therein and a buried layer in the cavity. The buried layer is an oxygen absorbing material. A dielectric layer disposed on the lower electrode and an upper electrode is disposed on the dielectric layer. The lower electrode may be a noble metal layer. The buried layer may fill in the cavity and may not contain oxygen (O2) when initially formed.

    摘要: A lower electrode is formed from a first metal on a semiconductor substrate. Atoms of a second metal, that is different than the first metal, are diffused into the lower electrode. A dielectric layer is formed on the lower electrode, and an upper electrode is formed on the dielectric layer. Diffusion of second metal atoms into the lower electrode may reduce or prevent crystal grain growth and agglomeration on a surface of the lower electrode during a subsequent high temperature process.

    摘要: In accordance with the present invention, a method of fabricating a concave capacitor is provided. The concave capacitor of the present invention includes an adhesion spacer is formed between a concave pattern comprising an interlayer dielectric film and a lower electrode is provided. In the concave capacitor fabricating method, an interlayer dielectric film is formal semiconductor substrate. A concave pattern having a storage node e exposing part of the upper surface of the semiconductor substrate is form by patterning the interlayer dielectric film. An adhesion spacer is formed on t sidewall of the concave pattern exposed by the storage node hole. A lower electrode to cover the adhesion spacer and the upper surface of the semiconductor substrate exposed by the storage node hole is formed in the storage node hole
