Patent ID: 6951047

Claim:
A surface acoustic wave element manufacturing method, comprising: forming a plurality of surface acoustic wave elements, each of the surface acoustic wave elements including a plurality of inter-digital transducer electrodes on a piezoelectric substrate, a grating reflector electrode arranged on each side of the plurality of inter-digital transducer electrodes, and a plurality of pad electrodes led from the inter-digital transducer electrodes and led from the grating reflector electrodes; forming dicing lines on an outer periphery of each surface acoustic wave element so that the plurality of pad electrodes of each surface acoustic wave element includes a plurality of isolated pad electrodes electrically isolated from the dicing lines, and includes a plurality of adjacent pad electrodes directly adjacent to at least one of the dicing lines; forming connecting electrodes for electrically connecting the isolated electrodes to a corresponding one of the adjacent pad electrodes; forming short-circuit electrodes for electrically connecting the adjacent pad electrodes to at least one of the dicing lines; forming pad reinforcing electrodes on the pad electrodes; removing at least a portion of each connecting electrode to electrically disconnect each isolated pad electrode from the corresponding one of the adjacent pad electrodes; and cutting the piezoelectric substrate along the dicing lines; wherein said removing of at least a portion of each connecting electrode is performed after said forming of the pad reinforcing electrodes.
