ABSTRACT:
A surface-acoustic-wave device wherein a plurality of metal strips (S) are provided on a propagation path of surface acoustic wave which is formed in a laminate comprised of a piezoelectric layer (23) and a semiconductor (1), the metal strips are extended onto the semiconductor outside the propagation path of surface acoustic wave, and depletion layer capacitance non-linearity created on the semiconductor surface at a region where the metal strips are extended is used as a main factor of a parametric interaction.
