摘要： The invention includes methods of forming layers comprising epitaxial silicon. In one implementation, an opening is formed within a first material received over a monocrystalline material. Opposing sidewalls of the opening are lined with a second material, with monocrystalline material being exposed at a base of the second material-lined opening. A silicon-comprising layer is epitaxially grown from the exposed monocrystalline material within the second material-lined opening. At least a portion of the second material lining is in situ removed. Other aspects and implementations are contemplated.

摘要： The invention includes a method of depositing a noble metal. A substrate is provided. The substrate has a first region and a second region. The first and second regions are exposed to a mixture comprising a precursor of a noble metal and an oxidant. During the exposure, a layer containing the noble metal is selectively deposited onto the first region relative to the second region. In particular applications, the first region can comprise borophosphosilicate glass, and the second region can comprise either aluminum oxide or doped non-oxidized silicon. The invention also includes capacitor constructions and methods of forming capacitor constructions.

摘要： An electrical contact includes a non-conductive spacer surrounding conductive plug material along the full height of the contact. The spacer inhibits oxide and other diffusion through the contact. In the illustrated embodiment, the contact includes metals or metal oxides which are resistant to oxidation, and additional conductive barrier layers. The contact is particularly useful in integrated circuits which include high dielectric constant materials.

摘要： A method of forming a capacitor includes forming a conductive metal first electrode layer over a substrate, with the conductive metal being oxidizable to a higher degree at and above an oxidation temperature as compared to any degree of oxidation below the oxidation temperature. At least one oxygen containing vapor precursor is fed to the conductive metal first electrode layer below the oxidation temperature under conditions effective to form a first portion oxide material of a capacitor dielectric region over the conductive metal first electrode layer. At least one vapor precursor is fed over the first portion at a temperature above the oxidation temperature effective to form a second portion oxide material of the capacitor dielectric region over the first portion. The oxide material of the first portion and the oxide material of the second portion are common in chemical composition. A conductive second electrode layer is formed over the second portion oxide material of the capacitor dielectric region.
