Title: Nucleation enhancement for chemical vapor deposition of diamond
Inventor: STONER BRIAN R
IPC: C23C16/511
Filed: 1992-12-18
Abstract: A method and apparatus for enhancing the nucleation of diamond by pretreating a substrate by electrically biasing a diamond film adjacent the substrate while exposing the substrate and the thus biased diamond film to a carbon-containing plasma. The bias pretreatment may be maintained for a time period in the range of about 1 hour to 2 hours to achieve a high diamond nucleation density.  Alternatively, the biasing may be continued until diamond film formation is indicated by a change in reflectivity of the surface of the substrate. The biasing pretreating may be used to nucleate diamond heteroepitaxially on a substrate having a surface film formed of a material having a relatively close lattice match to diamond, such as .beta.-silicon carbide. The apparatus includes a laser reflection interferometer to monitor the surface of the substrate. The laser reflection interferometer is used to monitor growth of the diamond film and cooperates with a controller to control the processing parameters during the diamond growing process.
