Abstract
Official abstract text for this publication.
An acoustic wave filter includes a piezoelectric substrate, an insulating pattern that has higher thermal conductivity than the piezoelectric substrate formed on the piezoelectric substrate, at least two pads formed on the piezoelectric substrate or the insulating pattern, at least one pad formed on the insulating pattern, at least one acoustic resonator formed on the insulating pattern, and at least one acoustic resonator directly formed on the piezoelectric substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. An acoustic wave filter, comprising: a piezoelectric substrate; an insulating pattern directly formed on a top surface of said piezoelectric substrate, said insulating pattern having a higher thermal conductivity than said piezoelectric substrate and being patterned to partially expose the top surface of the piezoelectric substrate; a first acoustic wave resonator including a first interdigital transducer, said first interdigital transducer being directl…
