Iridium and iridium oxide electrodes used in ferroelectric capacitors
The present invention provides a capacitor having upper and lower electrodes formed of iridium or iridium oxide or combinations thereof. The electrodes are preferably formed using physical vapor deposition. An insulating layer disposed between the electrodes can be a ferroelectric ceramic such as PZ...
