Abstract
A ceramic feedthrough for a package for an electronic device provides a plurality of electrical connections through an opening in the package. A method of making the feedthrough and of packaging the electronic device includes electrically conductive paths that are formed from a metal paste applied between green sheets that are joined and cofired to form a ceramic body. Vias extend from an exterior surface of the ceramic body to the paths to complete the electrical connection from outside the package to inside the package. A density of 50 paths per inch or greater may be achieved. The ceramic body may be hermetically sealed into an opening in the package and the body may have a peripheral extension to facilitate attachment of the feedthrough to the package.
