Abstract: HERMETIC PACKAGE FOR AN ELECTRONIC DEVICE AND METHOD OF MANUFACTURING SAME A hermetic package for an electronic device is manufactured by providing a green glass ceramic body with a green via to produce a workpiece. The workpiece is sintered at a temperature at or above 500.degree.C, while compressing the workpiece at a pressure at or above 100 pounds per square inch, so as to obtain a hermetic package. The green via comprises a mixture of copper and a glass ceramic material with a sufficient volume of glass to produce a hermetic package, yet with sufficient copper to have a suitable electrical conductivity. The hermetic package thus produced comprises a sintered glass ceramic body having an electrically conductive sintered via which is hermetically bonded to the glass ceramic body and which comprises a mixture of an electrically conductive material and a glass ceramic material. The electrically conductive material forms at most 50 volume percent of the via. The workpiece may be sintered in a sintering fixture having a frame and a compensating insert. The compensating insert and frame bound a sintering chamber for accommodating the workpiece. By providing a frame having a thermal expansion coefficient greater than that of the workpiece, and by providing a compensating insert having a thermal expansion coefficient greater than that of the frame, a close fit can be assured between the workpiece and the sintering fixture over a large range of temperatures.

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.

Abstract: A hermetic package for an electronic device is manufactured by providing a green glass ceramic body (10) with a green via (20)to produce a workpiece. The workpiece (24) is sintered at a temperature at or above 500 DEG C, while compressing the workpiece at a pressure at or above 100 pounds per square inch, so as to obtain a hermetic package. The green via comprises a mixture of copper and a glass ceramic material with a sufficient volume of glass to produce a hermetic package, yet with sufficient copper to have a suitable electrical conductivity. The hermetic package thus produced comprises a sintered glass ceramic body having an electrically conductive sintered via which is hermetically bonded to the glass ceramic body and which comprises a mixture of an electrically conductive material and a glass ceramic material. The electrically conductive material forms at most 50 volume percent of the via. The workpiece may be sintered in a sintering fixture having a frame (44) and a compensating insert (46). The compensating insert and frame bound a sintering chamber for accommodating the workpiece. By providing a frame having a thermal expansion coefficient greater than that of the workpiece, and by providing a compensating insert having a thermal expansion coefficient greater than that of the frame, a close fit can be assured between the workpiece and the sintering fixture over a large range of temperatures.
