ABSTRACT:
A surface acoustic wave device includes a transducer electrode formed on a substrate. In one aspect, the electrode has a plurality of layers. At least one of the layers is metal and another of the layers is a material for providing a hardening effect to the metal layer by reinforcement with Al2O3precipitates. In another aspect, the electrode is electrically connected to a metal component that permits electrical connection of the surface acoustic wave device to an electrical device external to the surface acoustic wave device. The electrode has a metal portion of a first metallization. The component is of a second, different metallization. In other aspects, the surface acoustic wave device is made via a method to have such structural aspects.
