  • Patterned ferroelectric thin films for microwave devices
    Patent number: 7465354
    Abstract: 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.
