    摘要: A method of forming a capacitor includes forming a conductive first capacitor electrode material comprising TiN over a substrate. TiN of the TiN-comprising material is oxidized effective to form conductive TiOxNy having resistivity no greater than 1 ohm·cm over the TiN-comprising material where x is greater than 0 and y is from 0 to 1.4. A capacitor dielectric is formed over the conductive TiOxNy. Conductive second capacitor electrode material is formed over the capacitor dielectric. Other aspects and implementations are contemplated, including capacitors independent of method of fabrication.

    摘要: An improved charge storing device and methods for providing the same, the charge storing device comprising a conductor-insulator-conductor (CIC) sandwich. The CIC sandwich comprises a first conducting layer deposited on a semiconductor integrated circuit. The CIC sandwich further comprises a first insulating layer deposited over the first conducting layer in a flush manner. The first insulating layer comprises a structure having a plurality of oxygen cites and a plurality of oxygen atoms that partially fill the oxygen cites, wherein the unfilled oxygen cites define a concentration of oxygen vacancies. The CIC sandwich further comprises a second conducting layer deposited over the first insulating layer in a strongly oxidizing ambient so as to reduce the concentration of oxygen vacancies in the first insulating layer, so as to provide an oxygen-rich interface layer between the first insulating layer and the second conducting layer, and so as to trap a plurality of oxygen atoms within the second conducting layer. The oxygen-rich interface layer and second conducting layer act as oxygen vacancy sinks for absorbing migrating oxygen vacancies that originate from the first insulating layer to thereby reduce the concentration of oxygen vacancies in the first insulating layer and to thereby reduce the buildup of oxygen vacancies at the interface layer. Thus, the first insulating layer provides an increased dielectric constant and an increased resistance to current flowing therethrough so as to increase the capacitance of the CIC sandwich and so as to reduce leakage currents flowing through the CIC sandwich.

    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.
