Abstract:
Some embodiments include a method of forming a capacitor. An opening is formed through a silicon-containing mass to a base, and sidewalls of the opening are lined with protective material. A first capacitor electrode is formed within the opening and has sidewalls along the protective material. At least some of the silicon-containing mass is removed with an etch. The protective material protects the first capacitor electrode from being removed by the etch. A second capacitor electrode is formed along the sidewalls of the first capacitor electrode, and is spaced from the first capacitor electrode by capacitor dielectric. Some embodiments include multi-material structures having one or more of aluminum nitride, molybdenum nitride, niobium nitride, niobium oxide, silicon dioxide, tantalum nitride and tantalum oxide. Some embodiments include semiconductor constructions.
Abstract:
Some embodiments include methods of forming conductive structures. An electrically conductive material may be deposited with a first deposition method. The first deposition method has a first deposition rate and forms a first portion of a conductive structure. A second portion of the conductive structure may be formed by depositing the electrically conductive material with a second deposition method having a second deposition rate. The second deposition rate may be different from the first deposition rate by at least about a factor of 3. In some embodiments, a region of the conductive structure is utilized as a transistor gate of a DRAM cell. Some embodiments include semiconductor constructions.
