Patent ID: 6919257

Claim:
A method of forming a capacitor, the method comprising: forming an opening in a substrate assembly, wherein the opening extends to a first surface of an interconnect recessed within the substrate assembly; forming a non-smooth mold in the opening and on the first surface of the interconnect; removing a portion of the non-smooth mold from the first surface of the interconnect; forming a first electrode having a non-smooth surface, wherein forming the first electrode includes forming the first electrode on the non-smooth mold and the first surface of the interconnect with a material selected from the group consisting of transition metals, conductive oxides, alloys thereof, and combinations thereof; forming a dielectric on the first electrode and an uppermost surface of the substrate assembly; and forming a second electrode on the dielectric and the uppermost surface of the substrate assembly, wherein forming the second electrode includes forming at least one non-smooth surface.
