ABSTRACT:
Adherent traces of a carbide-forming conductive metal are produced on a diamond surface, without deposition of carbide in areas to be non-conductive, by depositing an undercoat layer of a non-carbide-forming metal such as palladium, patterning said undercoat layer and then depositing a bond layer of the carbide-forming metal. The undercoat layer and the portion of the bond layer deposited thereon are then removed, typically by etching.
