Abstract:
1. An acoustic wave device, comprising: a substrate comprising a piezoelectric material; a first stack of layers on the substrate, the first stack of layers comprising at least one first metal layer over the substrate and a layer of a first monocrystalline piezoelectric material disposed completely on a surface of the at least one first metal layer a second metal layer disposed completely on a surface of the layer of the first monocrystalline piezoelectric material in the first stack, the first stack defining at least one bulk acoustic wave filter incorporating the first monocrystalline piezoelectric material; and a third metal layer over the substrate in a second area, wherein the first monocrystalline piezoelectric is absent in the second area, the second area defining at least one surface acoustic wave filter incorporating the piezoelectric material of the substrate.
