S. Yamauchi et M. Yoshimaru, HIGH RELIABLE LEAD-ZIRCONATE-TITANATE GROWTH USING REACTIVE SPUTTERING AND RAPID THERMAL ANNEALING, Integrated ferroelectrics, 14(1-4), 1997, pp. 159-166
High reliable lead-zirconate-titanate (PZT) thin films were produced b
y reactive sputter-deposition and rapid themal annealing (RTA). Severa
l important parameters for the film growth were investigated such as g
rowth temperature, substrate-biasing, target-substrate gap and film st
oichiometry. X-Ray Diffraction and Scanning Electron Microscopy reveal
ed a single (111)orientation and smooth surface of the controlled film
s, respectively. Measurement of electric properties of the controlled
100nm-thick PZT films revealed low leakage current (about 2x10(-7)A/cm
(2) at 3.5V) and without fatigue after 10(12) cycle bipolar switchings
