Abstract

PURPOSE:To reduce the propagation loss in a high frequency, by using an elastic substance substrate where an aluminum nitride single crystal film is formed on a silicon single crystal layer by the epitaxial method. CONSTITUTION:A silicon single crystal layer of one of crystal faces (111), (110), and (100) is formed on a silicon single crystal substrate 2 and is subjected to the heat treatment in an atmosphere containing an Al compound and a nitrogenous compound to grow epitaxially an Al nitride single crystal film 15 on the surface of the substrate 2. A pair of comb-shaped input electrodes 18 and 19 and an output electrode 20 between them are provided on this film 15, and input termials 18A and 19A and an output terminal 20A are provided on respective electrodes. Then, a substrate electrode 17 is provided to constitute a surface acoustic wave element. An input signal is applied to terminals 18A and 19A and is converted to a surface acoustic wave by electrodes 18 and 19 and is propagated to the electrode 20. In this case, two signal waves are mixed by the piezoelectric characteristics of the film 15 to generate an electric field, and only uniform components, which are not changed dependently upon positions, out of field components are outputted from the terminal 20A through the electrode 20.
