Patent ID: 7692266

Claim:
An integrated circuit comprising: a capacitor that comprises: an electrically conductive base electrode; a dielectric on the base electrode, the dielectric containing an oxide of a material contained in the base electrode; and an electrically conductive covering electrode, the covering electrode covering the dielectric such that a peripheral edge of the dielectric is uncovered by the covering electrode or that the covering electrode projects beyond the dielectric at its periphery; an electrically insulating base layer; the electrical insulating base layer being a separate component from the dielectric, the electrically insulating base layer that includes a cutout adjacent to the dielectric, the cutout being arranged on a side of the base electrode which faces the dielectric; the dielectric is produced by anodic oxidation; and the base electrode comprises a valve metal, a valve metal nitride, or a valve silicide of the metals Ta, Ti, Nb, Zr, or Hf.
