    摘要: A piezoelectric sensor comprising a piezoelectric film formed on a surface of an object to be monitored; a plurality of electrodes formed on a surface of the piezoelectric film; and wherein electrical polarization of the piezoelectric film is about coplanar with the surface of the piezoelectric film. A method of forming a piezoelectric sensor. The method comprises forming a piezoelectric film on a surface of an object to be monitored; forming electrodes on a surface of the piezoelectric film; and orientating electrical polarization in the piezoelectric film to be about coplanar with the surface of the piezoelectric film.

    摘要: A process, for patterning a thin film that is highly resistant to conventional etching processes and that is to be deposited at a high substrate temperature, is disclosed. The process uses a liftoff method wherein a refractory material has been substituted for the conventional organic resin. The method is particularly useful for the fabrication of tunable microwave devices and ferroelectric memory elements.
