Abstract
A thick film conductor composition adapted to be bonded to an aluminum nitride substrate is provided which comprises a sufficient amount of conductive metallic material to render the conductor composition electrically conductive when bonded to the substrate, a glass frit binder for the metallic material capable of being bonded to the substrate, and a lithium containing compound capable of reacting with the substrate upon heating so as to aid in adherently bonding the conductor composition to the aluminum nitride substrate. A thick film conductor bonded onto the surface of an aluminum nitride substrate as well as a method of producing the same are also provided.
