    摘要: Some embodiments include methods of forming capacitors. A metal oxide mixture may be formed over a first capacitor electrode. The metal oxide mixture may have a continuous concentration gradient of a second component relative to a first component. The continuous concentration gradient may correspond to a decreasing concentration of the second component as a distance from the first capacitor electrode increases. The first component may be selected from the group consisting of zirconium oxide, hafnium oxide and mixtures thereof; and the second component may be selected from the group consisting of niobium oxide, titanium oxide, strontium oxide and mixtures thereof. A second capacitor electrode may be formed over the first capacitor electrode. Some embodiments include capacitors that contain at least one metal oxide mixture having a continuous concentration gradient of the above-described second component relative to the above-described first component.

    摘要: A method of forming a capacitor includes depositing a dielectric metal oxide layer of a first phase to a thickness no greater than 75 Angstroms over an inner conductive capacitor electrode material. The first phase dielectric metal oxide layer has a k of at least 15. Conductive RuO2 is deposited over and into physical contact with the dielectric metal oxide layer. Then, the RuO2 and the dielectric metal oxide layer are annealed at a temperature below 500° C. The RuO2 in physical contact with the dielectric metal oxide during the annealing facilitates a change of the dielectric metal oxide layer from the first phase to a second crystalline phase having a higher k than the first phase. The annealed dielectric metal oxide layer is incorporated into a capacitor dielectric region of a capacitor construction. Other implementations are disclosed.

    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.
