    摘要: A method of forming a capacitor includes providing material having an opening therein over a node location on a substrate. A shield is provided within and across the opening, with a void being received within the opening above the shield and a void being received within the opening below the shield. The shield comprises a nitride. Etching is conducted within the opening through the nitride-comprising shield. After the etching, a first capacitor electrode is formed within the opening in electrical connection with the node location. A capacitor dielectric and a second capacitor electrode are formed operatively adjacent the first capacitor electrode. Other aspects and implementations are contemplated.

    摘要: A plurality of capacitor electrode openings is formed within capacitor electrode-forming material. A first set of the openings is formed to a depth which is greater within the capacitor electrode-forming material than is a second set of the openings. Conductive first capacitor electrode material is formed therein. A sacrificial retaining structure is formed elevationally over both the first capacitor electrode material and the capacitor electrode-forming material, leaving some of the capacitor electrode-forming material exposed. With the retaining structure in place, at least some of the capacitor electrode-forming material is etched from the substrate effective to expose outer sidewall surfaces of the first capacitor electrode material. Then, the sacrificial retaining structure is removed from the substrate, and then capacitor dielectric material and conductive second capacitor electrode material are formed over the outer sidewall surfaces of the first capacitor electrode material formed within the first and second sets of capacitor openings.

    摘要: Methods of forming semiconductor devices that include one or more container capacitors include anchoring an end of a conductive member to a surrounding lattice material using an anchor material, which may be a dielectric. The anchor material may extend over at least a portion of an end surface of the conductive member, at least a portion of the lattice material, and an interface between the conductive member and the lattice material. In some embodiments, the anchor material may be formed without significantly covering an inner sidewall surface of the conductive member. Furthermore, in some embodiments, a barrier material may be provided over at least a portion of the anchor material and over at least a portion of an inner sidewall surface of the conductive member. Novel semiconductor devices and structures are fabricated using such methods.

    摘要: Memory cell support lattices and methods of forming the same are described herein. As an example, a method of forming a memory cell support lattice includes forming a mask on a number of capacitor elements in an array, such that a space between vertically and horizontally adjacent capacitor elements is fully covered and a space between diagonally adjacent capacitor elements is partially covered and forming a support lattice in a support material by etching the support material to remove portions of the support material below the openings in the mask.
