Abstract
A cantilever actuator of piezoelectric thin films was fabricated on Si wafer for micro-electro-mechanical-system (MEMS) devices such as micro mirror array and accelerometer. The piezoelectric thin films, La doped lead zirconate titanate, (PLZT) were prepared on Pt/Ti/SiO2/Si-wafer by the sol-gel technique. Geometrically flat cantilevers were obtained using a stress balance layer. Electrical properties, dielectric constants and breakdown fields, of PLZT thin film were studied. The piezoelectric cantilever tip displacement, 6μm, was directly measured by laser interferometer on a 90 μm long cantilever at 10V.
