Multitarget sputtering of PZT-containing mixed oxide thin films onto copper-coated Kapton substrates

摘要

Large area film deposition was performed by means of multitarget reactive magnetron sputtering from 200 mm diameter metallic targets (Pb, Ti, Zr) onto Cu-coated Kapton HN substrates. High-power pulse sputtering has been employed for the Zr-target (or alternatively for the Ti-target). Film composition profiles were evaluated by XPS and RBS. Piezoelectric properties were investigated by PFM.
