    Abstract: A frit capacitor of either the discrete or integrated microcircuit variety having a ferroelectric glass-ceramic dielectric whose dielectric constant is of intermediate value between about 20 and 400. The desired value of dielectric constant is accurately obtained in a readily reproducible manner by mixing a batch containing appropriate quantities of stable non-crystallizable glass particles and glass particles capable of forming a ferroelectric crystal phase. The desired dielectric constant is obtained by subjecting the batch to heat treatment. By controlling the weight ratio of the two glass components during the batch preparation, individual capacitor dielectrics having different dielectric constants can be provided utilizing the same firing schedule for each.

    Abstract: UNIQUE DIELECTRIC COMPOSITIONS MAY BE USED TO FORMULATE THICK FILM PASTES FOR PRINTING MICROELECTRONIC CAPACITORS. THE RESULTING DIELECTRICS EXHIBIT DIELECTRIC CONSTANTS GREATER THAN ABOUT 500 AND CAPACITANCES GREATER THAN ABOUT 80,000 PICOFARADS PER SQUARE INCH AT A THICKNESS OF AT LEAST ABOUT 1.0 MIL. THE UNIQUE DIELECTRIC COMPOSITIONS COMPRISE ABOUT 55-76 PERCENT BY WEIGHT OF A FERROELECTRIC MATERIAL AND 45-24 PERCENT OF A GLASS BINDER. THE GLASS BINDER EMPLOYED COMPRISES A LEAD BARIUM BOROSILICATE GLASS AND A FERROELECTRIC MATERIAL PREVIOUSLY DISSOLVED THEREIN. THE COMPOSITION IS FORMULATED INTO A PRINTING PASTE BY FIRST DISSOLVING 20-30 PERCENT BY WEIGHT FERROELECTRIC INTO 70-80 PERCENT BY WEIGHT LEAD BARIUM BOROSILICATE GLASS BINDER, COOLING THE NEWLY FORMED GLASS TO A SOLID STATE COMMINUTING THE GLASS TO A PARTICLE SIZE OF LESS THAN ABOUT 1 MICRON AND THEREAFTER ADMIXING THE COMMINUTED GLASS WITH THE SAME PARTICULATE FERROELECTRIC IN AN AMOUNT AS INDICATED. THIS ADMIXTURE IS THEN ADDED TO A LIQUID ORGANIC CARRIER VEHICLE TO FORMULATE THE PRINTING PASTE. THE PRINTING PASTE IS THEN PRINTED INTO A CHOSEN DESIGN AND FIRED AT A TEMPERATURE OF APPROXIMATELY 1,0001,050*C. TO PRODUCE A HIGHLY DENSE, UNIFORM, AND SUBSTANTIALLY CRACK-FREE DIELECTRIC MATERIAL.

    Abstract: Novel glass-ceramics are prepared from glasses which consist essentially of critical proportionate amounts of SiO2, PbO, Al2O3, TiO2 and BaO; optional components thereof include ZnO, PbF2, SrO, ZrO2, Ta2O5, WO3, CdO, SnO2 and Sb2O3. The glasses are used, e.g., in particulate form, in preparing screen-printable crossover dielectric compositions, and as the inorganic binder component in preparing screen-printable conductor or resistor compositions, each of which may be fired to produce these novel glass-ceramics.
