Abstract

PURPOSE:To intend the miniaturization of an element and a noize decrease by piling and arranging an occurring portion of an elastic surface wave SAW and an amplification portion upon an laminating layer direction of a piezoelectric body layer and a semiconductor layer. CONSTITUTION:A ZnO piezoelectric body 11 is piled upon a P-type Si 14 through a SiO2 film 13 and a comb-type electrode 12 is attached thereto. A couple of N<+> layers for direct current electrode are embed towards a propagation direction A on the surface of the Si 14. After an AC and a DC are connected to the electrode 12, the Si 14 is earthed. A depletion layer 18 and a inversion layer 19 are caused on the surface of Si 14 by DC power source. When the AC is applied, the SAW occurs on layer 11. On the other hand, when the voltage is applied toward the A direction of the AC electrode 15, free electric charges in layer 19 increase the amplitude of SAW. At this time, the SAW of the reverse direction against A is damped by the DC electric field of the electrode 15. Further, since the electrode 12, and 15a and 15b are piled up in the laminated direction, the device is miniaturized without extending horizontally.
