  • Nucleation of diamond films using an electrode
    Patent number: 5961719
    Abstract: Method and apparatus are disclosed for growing diamond films on a non-diamond substrate, such as a silicon wafer. The substrate surface is subjected to nucleation by means of a microwave-generated plasma while applying an electrical bias to the substrate and while an electrode is positioned adjacent to but spaced from the substrate surface. After the nucleation step, crystalline diamond is deposited on the nucleated surface from a carbon-containing plasma.
