Abstract

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.
