The present invention is intermittent process for growing diamond film on silicon chip, and belongs to the technological field of chemically vapor depositing inorganic non-metal material. In an available thermal filament chemical vapor deposition plant, diamond film is grown in an intermittent circular process, in which hydrogen is introduced intermittently to etch diamond film so as to reduce the content of graphite in the film. The said process can make diamond film with excellent electric performance for making detector. |
