Abstract
Abstract Capacitors having defect isolation and bypass characteristics. The capacitors include a first electrode, a second electrode containing electrode segments, and a dielectric layer interposed between the first electrode and second electrode. The electrode segments of the second electrode are physically separated from other electrode segments. The capacitors further include an interconnection bus electrically coupling the electrode segments of the second electrode. Selective isolation of one or more electrode segments permits isolation and bypass of any defects identified in those electrode segments.
