摘要： The present invention is directed to preventing characteristic variations and damage caused by a difference in thermal expansion coefficient. A piezoelectric thin film filter, including four film bulk acoustic resonators, has a configuration where a filter section for providing a filter function of the piezoelectric thin film filter is bonded with a flat base substrate mechanically supporting the filter section via an adhesive layer. In manufacturing of the piezoelectric thin film filter, a piezoelectric thin film is obtained by performing removal processing on a piezoelectric substrate that can individually stand up under its own weight, but substrates made of one kind of single crystal material are adopted as the base substrate and the piezoelectric substrate, to make the respective thermal expansion coefficients of the piezoelectric thin film and the base substrate coincident with each other.

摘要： The present invention is directed to improving characteristics of a piezoelectric thin film device. A piezoelectric thin film filter including four film bulk acoustic resonators has a configuration where a filter section and a base substrate are bonded to each other via an adhesive layer, the filter section including a piezoelectric thin film which cannot stand up individually under its own weight, the flat base substrate mechanically supporting the filter section. As a piezoelectric material constructing the piezoelectric thin film, it is desirable to use a single-crystal material including no grain boundary, selected from crystal, lithium niobate, lithium tantalite, lithium tetraborate, zinc oxide, potassium niobate, and langasite.

摘要： In a piezoelectric thin film device of the present invention, the degree of flexibility is enhanced in selection of a piezoelectric material constituting a piezoelectric thin film and the crystal orientation in the piezoelectric thin film. A piezoelectric thin film filter, including four film bulk acoustic resonators, has a configuration where a filter section for providing a filter function of the piezoelectric thin film filter is bonded with a flat base substrate mechanically supporting the filter section via an adhesive layer. In manufacturing of the piezoelectric thin film filter, a piezoelectric thin film is obtained by performing removal processing on a piezoelectric substrate, but the piezoelectric thin film obtained by removal processing cannot independently stand up under its own weight. For this reason, a prescribed member including the piezoelectric substrate is previously bonded to the base substrate as a support prior to the removal processing.
