  • Method for flat firing aluminum nitride/tungsten electronic modules
    Patent number: 5932043
    Abstract: A method and apparatus for flattening a ceramic body comprised primarily of an aluminum nitride system having a liquid phase additive necessary for low temperature sintering during a firing thereof is disclosed. The ceramic body is referred to as an aluminum nitride multilayer ceramic (AlN MLC). The method and apparatus include a support tile having a first coating on a contact surface thereof, the AlN MLC for being placed upon the contact surface of the support tile. A load flattening tile having a second coating on a contact surface thereof is provided, the load flattening tile for being placed with its coated surface upon and in contact with the AlN MLC. Lastly, a furnace is provided for heating the support tile, AlN MLC, and load flattening tile at temperatures greater than 1500.degree. C.

  • Aluminum nitride body having graded metallurgy
    Patent number: 5763093
    Abstract: Disclosed is an aluminum nitride body having graded metallurgy and a method for making such a body. The aluminum nitride body has at least one via and includes a first layer in direct contact with the aluminum nitride body and a second layer in direct contact with, and that completely encapsulates, the first layer. The first layer includes 30 to 60 volume percent aluminum nitride and 40 to 70 volume percent tungsten and/or molybdenum while the second layer includes 90 to 100 volume percent of tungsten and/or molybdenum and 0 to 10 volume percent of aluminum nitride.
