Abstract

New approaches for improving fatigue performance of sol-gel PZT based ferroelectric capacitors with RuO2 electrodes are discussed. The use of thin (∼5 nm) high-Ti PZT seed layer was found to be effective for improving fatigue performance. For an optimized seedlayer thickness, FECAPs with excellent fatigue characteristics (less than 10% decrease in Pr after 1011 cycles) were obtained.
