  • Method of preparing multilayered piezoelectric ceramic material
    Patent number: 6964718
    Abstract: Co-fired multilayer piezoelectric ceramic materials with base metal electrodes based on copper, copper alloy, are found as an effective approach to manufacture low cost multilayer piezoelectrics. The method of the invention is performed at low firing temperature and without the oxidation of base metal or reduction of ceramic components. A variety of ceramic materials may be used and copper is the preferred base metal in the multi-layer piezoelectric devices of the invention. This copper has additional protection against oxidation with a small inorganic coating on the surface. With such protection, the binder and other organics can also be efficiently removed and produce superior performance in the piezoelectric structured devices.

  • Integrated passive device and method for producing such a device
    Patent number: 6700772
    Abstract: An IPD has a varistor of electrodes and a ZnO dielectric. A capacitor includes electrodes and a dielectric that has oxides of bismuth, magnesium, and niobium having a pyrochlore structure of type A2B2O7. The materials are applied as wet layers and are sintered for integrated production.
