Method for manufacturing an acoustic surface wave interaction device
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.
