  • Hybrid metal/metal oxide electrodes for ferroelectric capacitors
    Patent number: 5555486
    Abstract: Ferroelectric capacitors with hybrid electrodes including both a conducting oxide and a noble metal may be used to achieve devices having improved performance over capacitors with either platinum or ruthenium oxide electrodes. These hybrid electrode structures can improve capacitor performance both in terms of fatigue and leakage current. Accordingly, these ferroelectric capacitors with hybrid electrodes can be used as elements of an integrated circuit such as a non-volatile memory or dynamic random access memory.
