    摘要: For forming stacked capacitors, an opening is formed through at least one semiconductor material. A lower electrode material is patterned within the opening to form a plurality of lower electrodes within the opening. The stacked capacitors are formed with the lower electrodes within the opening by depositing a capacitor dielectric and an upper electrode within the opening. With such a relatively large opening, a capacitor dielectric of the stacked capacitors is deposited with a large thickness for improving reliability of the stacked capacitors.

    摘要: In a node structure under a capacitor in a ferroelectric random access memory device and a method of forming the same, top surfaces of the node structures are disposed at substantially the same level as a top surface of an interlayer insulating layer surrounding the node structures, and thus crystal growth of a ferroelectric in the capacitor can be stabilized. To this end, a node insulating pattern is formed on a semiconductor substrate. A node defining pattern surrounding the node insulating pattern is disposed under the node insulating pattern. A node conductive pattern is disposed between the node defining pattern and the node insulating pattern.

    摘要: A semiconductor memory device and a method for forming the same. The method includes forming an insulating layer on a semiconductor substrate having a conductive region, forming a contact hole that exposes the conductive region by etching the insulating layer, forming a barrier metal layer that covers a sidewall and a bottom of the contact hole, and forming a contact plug in the contact hole by interposing the barrier metal layer therebetween. An etching process may be preformed that recesses the barrier metal layer and the contact plug in such a manner that a top surface of the contact plug protrudes upward beyond a top surface of the barrier metal layer. A capping plug may be formed covering the recessed barrier metal layer and the recessed contact plug. A capacitor may be formed on the capping plug.

    摘要: Methods for forming an electronic device can include forming a capacitor structure on a portion of a substrate with the capacitor structure including a first electrode on the substrate, a capacitor dielectric on the first electrode, a second electrode on the dielectric, and a hard mask on the second electrode. More particularly, the capacitor dielectric can be between the first and second electrodes, the first electrode and the capacitor dielectric can be between the second electrode and the substrate, and the first and second electrodes and the capacitor dielectric can be between the hard mask and the substrate. An interlayer dielectric layer can be formed on the hard mask and on portions of the substrate surrounding the capacitor structure, and portions of the interlayer dielectric layer can be removed to expose the hard mask while maintaining portions of the interlayer dielectric layer on portions of the substrate surrounding the capacitor structure. The hard mask can then be removed thereby exposing portions of the second electrode while maintaining the portions of the interlayer dielectric layer on portions of the substrate surrounding the capacitor.
