Abstract:
1. A method for forming a capacitor stack comprising: (i) forming a first material on a substrate, wherein the first material is operable as a first electrode of the capacitor stack; (ii) forming a second material on the first material, wherein the second material is operable as a first dielectric of the capacitor stack; (iii) forming a third material on the second material, wherein the third material is operable as a second dielectric of the capacitor stack and the third material is formed using a method comprising the steps of: (iv) forming a fourth material on the third material, and the fourth material is operable as a third dielectric of the capacitor stack; and (v) forming a fifth material on the fourth material, wherein the fifth material is operable as a second electrode of the capacitor stack.
