Abstract

CAPACITORS DEPOSITION ELECTRIC CONDUCTIVITY ELECTRODES FILM GROWTH LANTHANUM COMPOUNDS MAGNETRONS MULTILAYERS NIOBATES PZT SPUTTERING
Highly (100)‐oriented LaNiO 3 (LNO) thin films were grown on Si, SiO 2 /Si, Pt/SiSiO 2 /Si, as well as glass substrates by rf magnetron sputtering deposition at substrate temperatures ranging from 150 to 500 °C. As‐deposited LNO films are metallic; those prepared at substrate temperature ∼150–250 °C have a resistivity of 0.4–0.5 mΩ cm and can be used as the bottom electrode for the fabrication of integrated ferroelectric capacitors on Si. A subsequent deposition of sol‐gel derived Pb(Zr 0.53 Ti 0.47 )O 3 (PZT) thin film on the LNO‐coated substrate was also found to have a significant (100)‐ and (001)‐oriented texture. The ferroelectric capacitor fabricated from these films displays a good P–E hysteresis characteristic. © 1995, American Institute of Physics. All rights reserved.
