Abstract: In piezoelectric thin films constituting crystalline dielectric thin film elements used for a piezoelectric actuator of a liquid discharge head, stress is generated in the crystallization step by heating due to the lattice misfit. Given this fact, by interposing between a substrate and intermediate layer which has a twin structure that absorbs the stress, film peeling and deterioration of the piezoelectric properties of the piezoelectric thin films are prevented. The intermediate layer is of a multi-layer structure which has a first intermediate layer comprising a twin structure thin film and a second intermediate layer which is the lower electrode, and because the substrate also serves as a lower electrode, the intermediate layer has a single layer structure comprising a twin structure thin film.
Abstract translation: 在构成用于液体排出头的压电致动器的结晶电介质薄膜元件的压电薄膜中，由于晶格失配，通过加热在结晶步骤中产生应力。 鉴于这一事实，通过插入具有吸收应力的双结构的基板和中间层之间，防止了压电薄膜的膜剥离和压电性能的劣化。 中间层是具有包括双结构薄膜的第一中间层和作为下电极的第二中间层的多层结构，并且由于基板也用作下电极，所以中间层具有单个 层结构包括双结构薄膜。
