Abstract:
A substrate for a surface acoustic wave device or bulk acoustic wave device, comprising a support substrate and an piezoelectric layer on the support substrate, wherein the support substrate comprises a semiconductor layer on a stiffening substrate having a coefficient of thermal expansion that is closer to the coefficient of thermal expansion of the material of the piezoelectric layer than that of silicon, the semiconductor layer being arranged between the piezoelectric layer and the stiffening substrate.

Claim (Index 12):
Method of manufacturing a substrate comprising:\n transferring a semiconductor layer from a first donor substrate onto a stiffening substrate, to form a support substrate; and transferring a piezoelectric layer onto the semiconductor layer from a second donor substrate, such that the semiconductor layer is disposed between the piezoelectric layer and the stiffening substrate, wherein the stiffening substrate has a coefficient of thermal expansion closer to a coefficient of thermal expansion of a material of the piezoelectric layer than that of silicon.
