摘要： The present invention is directed to a substrate for subsequent eutectic bonding with a subsequently applied metal to provide, or as a precursor to the provision of, a circuit substrate. The circuit substrate comprises a dielectric film and a layer of an oxide or oxides of a metal on the film. The metal oxide layer has been formed by sputtering the metal of the metal oxide or oxides onto a surface of the film in the presence of an inert atmosphere save for at least one reactive gas content to provide the oxygen of the oxides.
