Patent ID: 7732852

Claim:
A method for forming a capacitor having a first electrode having a first transition metal layer in contact therewith and a second electrode having a second transition metal layer in contact therewith, the method comprising: forming the first transition metal layer comprising one of transition metal nitride; forming the second transition metal layer comprising another transition metal nitride and having an exposed surface; annealing the exposed surface of the second transition metal layer in a presence of oxygen for increasing a density of the second transition metal layer and for oxidizing at least the second transition metal layer at a temperature in a range of about 600° C. to about 900° C. for a period of about two minutes forming a high dielectric film of mixed transition metal oxides of one of Ti—W—O and Ti—Ta—O having a high dielectric constant >100; and forming the second electrode over the annealed second transition metal layer.
