  • Ceramic composition and method of making same
    Patent number: 6133175
    Abstract: Multiphase ceramic materials for use in multilayered device fabrication may be fabricated by providing novel glassy precursor materials of a preferred composition, with operable amounts of a non-glassy filler materials. The combined materials are fired at appropriate temperatures, so that a non-glassy anorthite type phase is formed. Material so fabricated is formed in a self-limiting process, in that reaction between the glassy precursor material and the non-glass filler material is terminated when one constituent of the glassy precursor material is fully consumed. The materials of the instant invention, fabricated according to the method disclosed herein, demonstrate excellent dielectric constant, and electrical loss characteristics.
    Type: Grant
    Filed: January 8, 1998
    Date of Patent: October 17, 2000
    Assignee: Motorola, Inc.
    Inventors: Shelly J. Bethke, Ross A. Miesem, Wayne W. Chiou, Rickey G. Pastor
