Abstract0.9Pb(Zr 0.53,Ti 0.47)O 3-0.1Pb(Zn 1/3,Nb 2/3)O 3 (PZT-PZN) thin films and integrated cantilevers have been fabricated. The PZT-PZN films were deposited on SiO 2/Si or SiO 2/Si 3N 4/SiO 2/poly-Si/Si membranes capped with a sol-gel-derived ZrO 2 buffer layer. It is found that the membrane layer stack, lead content, existence of a template layer of PbTiO 3 (PT), and ramp rate during film crystallization are critical for obtaining large-grained, single-phase PZT-PZN films on the ZrO 2 surface. By controlling these parameters, the electrical properties of the PZT-PZN films, their microstructure, and phase purity were significantly improved. PZT-PZN films with a dielectric constant of 700 to 920 were obtained, depending on the underlying stack structure. © 2010 TMS.
