Title: Piezoelectric film
Inventor: SHIBATA NORIYOSHI
IPC: B32B7/02
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric film in which temperature dependence of the characteristic values or the characteristics can be controlled while suppressing occurrence of defect by laminating piezoelectric layers of different composition or composition ratio through interfaces thereby forming a piezoelectric film. SOLUTION: A thin PLZT film (y=0.5) 8 of about 0.5 μm thick is formed on a thin platinum film 6 of about 10 nm thick formed on a silicon substrate 4, for example, and a thin PLZT film (y=0.65) 10 of about 0.5 μm thick is formed thereon. After repeating the film deposition process, a thin platinum film 12 of about 10 nm thick is formed on the thin PLZT film 10. It is then taken out from a sputtering system and thermally annealed in oxygen atmosphere to form a piezoelectric film 14 and a piezoelectric element. In such a piezoelectric film 14, even if a defect is present in one piezoelectric layer (any one of thin films 8, 10), it is confined within the film thickness and can be prevented easily from penetrating the entire piezoelectric film 14. Furthermore, a preferable dielectric constant can be obtained along with preferable temperature characteristics for resonance frequency.
