    摘要: A method for fabricating a cylindrical capacitor. The method includes forming an isolation structure including an interlayer on a substrate, the substrate having a plurality of contact plugs formed therein, forming a plurality of opening regions by etching the isolation structure, thereby exposing selected portions of the contact plugs, forming storage nodes on a surface of the opening regions, etching selected portions of the isolation structure to form a patterned interlayer that encompasses selected portions of the storage nodes, thereby supporting the storage nodes, removing remaining portions of the isolation structure, and removing the patterned interlayer to expose inner and outer walls of the storage nodes.

    摘要: A method for fabricating a capacitor includes forming an isolation layer over a cell region and a peripheral region of a substrate. The isolation layer forms a plurality of open regions in the cell region. Storage nodes are formed on surfaces of the open regions. A sacrificial pattern is formed over the isolation layer and covers the cell region. The isolation layer is etched in the peripheral region to expose side portions of the resulting structure obtained after forming the sacrificial pattern in the cell region. With the sacrificial pattern supporting the storage nodes, the isolation layer in the cell region is removed. The sacrificial pattern is then removed.
