Patent ID: 8828836

Claim:
A method for fabricating a capacitor stack, the method comprising: forming a first electrode layer on a substrate, wherein the first electrode layer comprises molybdenum oxide wherein the first electrode layer further comprises oxygen-rich molybdenum oxide (MoO 2+x ); forming a dielectric layer on the first electrode layer, wherein the dielectric layer comprises titanium oxide having at least a partially rutile crystal structure, and wherein molybdenum oxide of the first electrode layer promotes growth of the rutile crystal structure of titanium oxide of the dielectric layer when the dielectric layer is formed; annealing the dielectric layer using a millisecond anneal process, wherein the millisecond anneal process comprises raising the temperature of the substrate from an initial temperature to an annealing temperature in less than one second, wherein the annealing utilizes one or more flash lamps, wherein the annealing converts titanium oxide of the dielectric layer into the rutile crystal structure; and forming a second electrode layer on the dielectric layer, wherein the dielectric layer is annealed prior to forming the second electrode layer.
