Patent ID: 8105896

Claim:
A method of forming a capacitor, comprising: forming a conductive inner capacitor electrode material over a substrate; forming a capacitor dielectric over the inner capacitor electrode material; depositing a first conductive TiN-comprising layer over the capacitor dielectric; oxidizing the first conductive TiN-comprising layer effective to form an insulative TiO 2 layer; and after the oxidizing, forming conductive outer capacitor electrode material over the capacitor dielectric, the conductive outer capacitor electrode material comprising conductive TiN received outwardly of conductive TiO x N y , forming of the conductive TiO x N y comprising depositing a conductive second TiN-comprising layer onto the insulative TiO 2 layer and forming the conductive TiO x N y from interaction of TiN of the second TiN-comprising layer with the TiO 2 , the conductive TiO x N y having resistivity no greater than 1 ohm·cm where x is greater than 0 and y is from 0 to 1.4.
