Title:
COMPOSITE SUBSTRATE, AND ELASTIC WAVE ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/209131
Kind Code:
A1
Abstract:
A composite substrate 1 is provided with a first substrate 10 comprising a piezoelectric single crystal, and a second substrate 20 comprising a silicon single crystal joined to the first substrate 10. The planar orientation of the second substrate 20 is (111) and angle ψ of the Euler angles (φ, θ, ψ) is shifted away from 0°. Spurious bulk waves in a specific frequency band can thereby be reduced.
