Patent ID: 8853049

Claim:
A method for forming a capacitor stack, the method comprising: forming a first electrode layer on a substrate, wherein the first electrode comprises molybdenum oxide; forming a first dielectric material on the first electrode layer, wherein the first dielectric material comprises a first dopant; forming a second dielectric material on the first dielectric material, wherein the second dielectric material comprises a second dopant, wherein at least one of the first dielectric material or the second dielectric material has a nanolaminate structure, and wherein the second dielectric material is a different material from the first dielectric material; forming a second electrode layer on the second dielectric material; and performing an annealing step wherein more than 30% of the first dielectric material is present in a rutile phase after the annealing step, and wherein the second dielectric material is less than 30% crystalline after the annealing step.
