Abstract: PURPOSE: A method for producing piezoelectric films with a rotating magnetron sputtering system is provided to use in fabricating acoustic resonators and semiconductor devices. CONSTITUTION: The method comprises determining the surface roughness of an insulating layer on which the piezoelectric film is to be deposited and achieving a surface roughness for the insulating layer that is sufficiently low to achieve the high-quality piezoelectric film. Thus, the low surface roughness for the insulating layer is achieved with use of a rotating magnet magnetron system for improving the uniformity of the deposited layer. Accordingly, the high-quality piezoelectric film is assured by optimizing deposition parameters including determination of a "cross-over point" for reactive gas flow and/or monitoring and correcting for the surface roughness of the insulating layer pre-fabrication of the piezoelectric film.
