PROCEDE DE FABRICATION D'UN DISPOSITIF A INTERACTION D'ONDES ACOUSTIQUES SUPERFICIELLES

摘要

A method for manufacturing an acoustic surface wave interaction device includes the steps of forming an interdigitated electrode array on one flat surface of a piezoelectric plate, covering the interdigital electrode with a thin layer of dielectric material, and applying a predetermined DC voltage across the thickness of the piezoelectric plate for polarization.
