摘要： A thick film metallization compatible with low temperature cofired ceramics (LTCC) that displays very low microwave insertion losses commensurate with those of thin film gold. However, the disclosed metallization is applied similar to conventional metallizations by screen printing and has no limit to the number of layers achievable. The electrical performance of the metallization is attained by using a spherical metal particle shape and uniform particle size distribution in the thick film paste. The advantage of this invention is that superior microwave performance can be achieved in electronic packages without the cost and limitations imposed by thin film metallization techniques.

摘要： A planar phase shifter formed of multiple layers of a ferrite. Selected layers of the ferrite are patterned with a conductor and the multiple layers of magnetic dielectric and conductor are cofired. The phase shifter is fabricated by first obtaining ferrite powder. Then, layers of the ferrite are made, preferably by tape casting.

Selected numbers of vias are placed through selected layers of tape and conductive metal is placed in the vias to provide vertical connections through the layers. The tape layers are then stacked in a predetermined order and are laminated. The laminated stack of layers is then fired to a temperature of approximately 800.degree. C. to 1000.degree.

摘要： A method for forming a low temperature cofired ceramic package which is made using a multi-layered densified spherical powder formed via a sol-gel process. This densified powder is formed from layers of SiO.sub.2 reacted with trimethyl borate. The spherical powder has a preselected particle size and boron content sufficient to render the low temperature cofired ceramic package fully dense, even in the presence of a second phase filler ceramic, at a sintering temperature below 1000.degree. C. Binder material is added to the spherical powder and ceramic filler to form a plurality of tapes. A ceramic assembly is then formed by layering the plurality of tapes upon one another and firing the ceramic assembly at a temperature below 1025.degree. C. to form a fully dense cofired ceramic package. In order to form the multi-layered densified spherical powder, a silica core, which is formed using a sol-gel process, is reacted with trimethyl borate. An additional layer of silica is provided upon the reacted product which, in turn, is reacted with trimethyl borate. This process is continued until a spherical powder of desired size is formed.

Very fine (sub-micron) ferrite powders made by sol-gel methods are mixed with solvents and binders then tape-cast.

摘要： A dual mode radar transparency allowing passage of both RF radiation and IR radiation comprises an aerogel base and ceramic skin overlaying the aerogel base. The aerogel base comprises a low density ceramic material. A method of fabricating a dual mode radar transparency allowing passage of both RF radiation and IR radiation comprises the steps of preparing a colloidal dispersion of a ceramic material in a medium, increasing a concentration of the colloidal dispersion by evaporation to create a suspension, and placing the suspension in a mold. The suspension is solidified to form an aerogel and the aerogel is joined to a ceramic skin.

摘要： We disclose a fabrication method for integrating passive devices such as capacitors, resistors and circulators into ceramic packages for electronic systems. The method utilizes a glass or glass/ceramic as a bonding agent which is incorporated as one of the layers in the multilayer package. The integration of such passive devices eliminates the tedious mounting of these devices on the package, permitting a smaller, more reliable, less expensive and lighter weight product. This method allows the integration of passive devices having firing temperatures far different from that of the ceramic package itself, permitting combinations of materials that cannot be densified, or cofired together.

摘要： A system for incorporating superconductor circuits and semiconductor circuits in multilayered structures. A carrier material is chosen that is a good thermal match with the preferred superconductor substrates. The preferred superconductor substrate materials are lanthanum aluminate, magnesium oxide and neodymium gallate. The substrate carrier material should provide adequate thermal match through the range of operating temperatures which are preferably from room temperature to 77K. The preferred carrier material is a low temperature cofired ceramic (LTCC) which allows for multilayered structures to be developed which incorporate the superconductor circuitry and the semiconductor elements. The LTCC is composed of crystalline quartz particles in a borosilicate glass matrix. The percentage of quartz may be adjusted to adjust the thermal expansion characteristics of the LTCC.
