Patent ID: 7299528

Claim:
A method of manufacturing a surface acoustic wave device on a piezoelectric substrate, said method comprising: forming a patterned resist layer on said piezoelectric substrate having gaps present therein exposing portions of said piezoelectric substrate in superimposition therewith; forming a plurality of waveguide elements by forming, within said gaps, multiple layers of conductive material, with said plurality of waveguide elements defining a resonant frequency associated therewith; and varying said resonant frequency associated with a subset of said plurality of waveguide elements by removing one of said multiple layers associated with said subset, wherein forming said plurality of waveguide elements further includes forming a first conductive layer over said patterned resist layer and said portions and forming a second conductive layer over said first conductive layer, with said second conductive layer having a thickness at least as great as a thickness of said first conductive layer.
