Potential lithographic hot spots associated with a lithographic level are marked by a marker layer identifying a marked region. In the present invention, a sensitive film is positioned on a surface of a substrate, wherein a conductive layer is formed on the surface of the substrate. a drill bit, a reamer shoe or a stabilizer, are protected by at least temporarily fixing a super-hard material to the surfaces of the down-hole tool, and spray fusing a binding material around the super-hard material to permanently bind the super-hard material to the down hole tool.
