发明名称 METHOD FOR MANUFACTURING SURFACE ACOUSTIC WAVE DEVICE
摘要 <p>A method for manufacturing a surface acoustic wave device comprising a first conductive pattern and a second conductive pattern having different thicknesses on the same piezoelectric substrate. The surface acoustic wave device having a plurality of electrode films with different thicknesses on the same piezoelectric substrate is manufactured with excellent accuracy by combining a plurality of steps of forming metal films and an etching step.</p>
