Patent ID: 7148146

Claim:
A method of fabricating a capacitor on a substrate comprising the steps of: performing capacitor foundation formation on the substrate; depositing polish stop layer material on the capacitor foundation and the substrate; etching a first capacitor electrode region on the capacitor foundation formation and a transistor gate region on the substrate; depositing a first conductive material in the etched first capacitor electrode region and the transistor gate region; performing chemical mechanical polishing on the deposited first conductive material to yield a gate electrode and a first capacitor electrode; depositing a dielectric material over the gate electrode and the first capacitor electrode; etching a second capacitor electrode region in the dielectric material over the first capacitor electrode and into the first capacitor electrode material; forming a capacitor dielectric layer over the first capacitor electrode; depositing a second conductive material in the etched second capacitor electrode region; and performing chemical mechanical polishing on the deposited second conductive material to yield a second capacitor electrode.
