MANUFACTURING METHOD FOR SURFACE ACOUSTIC WAVE ELEMENT

摘要

PROBLEM TO BE SOLVED: To efficiently assign interdigital electrodes of surface acoustic wave elements to a piezoelectric substrate. SOLUTION: In the exposure to assign interdigital electrodes of the surface acoustic wave elements to the piezoelectric substrate, the rhombic interdigital electrodes are assigned to the piezoelectric substrate and exposed in a way that rhombic sides of the rhombic interdigital electrodes are adjacent to each other among adjacent chips.
