Patent ID: 7314795

Claim:
A method for forming an integrated circuit device, the method comprising: forming a first conductive electrode on a substrate, the first conductive electrode having an electrode wall extending away from the substrate; forming an insulating spacer on the electrode wall wherein portions of the electrode wall are free of the insulating spacer between the substrate and the insulating spacer; forming a capacitor dielectric layer on portions of the first conductive electrode free of the spacer; and forming a second conductive electrode on the capacitor dielectric layer opposite the first conductive electrode, wherein a thickness of the insulating spacer between the first and second conductive electrodes is greater than a thickness of the capacitor dielectric layer between the first and second conductive electrodes; wherein portions of the electrode wall extend beyond the spacer away from the substrate free of the insulating spacer, and wherein the capacitor dielectric layer is also on portions of the electrode wall extending beyond the spacer.
