ACOUSTIC WAVE DEVICE AND METHOD OF FABRICATING THE SAME |
摘要 |
An acoustic wave device includes: a substrate; a functional element formed on the substrate and including an excitation electrode that excites an acoustic wave; a columnar electrode formed on the substrate and electrically connected to the excitation electrode; a metal frame body formed on the substrate and surrounding the functional element and the columnar electrode; and a ceramic substrate sealing the functional element in combination with the metal frame body, a first metal layer bonded to the columnar electrode and a second metal layer bonded to the metal frame body being formed on a surface of the ceramic substrate. |
