Patent ID: 8288240

Claim:
A method of making an MIM capacitor, the method comprising the steps of: (a) forming an opening in an insulator layer on a substrate; (b) depositing a first metal layer on the insulator layer and in the opening; (c) removing the first metal layer from the insulator layer and a first wall of the opening; (d) depositing a dielectric over the insulator and into the opening so as to cover the first metal layer; (e) depositing a second metal layer; (f) removing the second metal layer from the dielectric layer and a second wall of the opening, wherein the second wall is different from the first wall; (g) repeating steps (d), (e) and (f) a predetermined number of times until the desired number of metal layers is formed wherein the removing of the metal layer alternates between the first and second walls; (h) filling the opening with a dielectric material; and (i) forming electrical contacts with the metal layers.
