  • Method for forming a multi-frequency surface acoustic wave device
    Publication number: 20040083590
    Abstract: Provided is a method of manufacturing a multi-frequency surface acoustic wave (SAW) device on a common piezoelectric substrate. The method features varying the resonant frequency of waveguide elements of the SAW device using a single etch step. The etch step removes a sub-portion of multiple layers of conductive film disposed on the substrate.
