Method of manufacturing a surface acoustic wave element

   
   

A method of manufacturing a surface acoustic wave element includes the steps of providing a piezoelectric body having an interdigital transducer, where the interdigital transducer is made of a metal having a higher density than the piezoelectric body, and performing ion bombardment of the interdigital transducer and the piezoelectric body simultaneously so as to reduce the thickness of the interdigital transducer and the piezoelectric body.

Um método de manufaturar um elemento de superfície da onda acústica inclui as etapas de fornecer um corpo piezoelectric que tem um transdutor interdigital, onde o transdutor interdigital seja feito de um metal que tem uma densidade mais elevada do que o corpo piezoelectric, e executando o bombardeio do íon do transdutor interdigital e do corpo piezoelectric simultaneamente para reduzir a espessura do transdutor interdigital e do corpo piezoelectric.
