Electron beam treatment of fluorinated silicate glass

摘要

The invention pertains to dielectric films for the production of microelectronic devices. A relatively stabile fluorinated silicate glass film is produced by depositing a fluorinated silicate glass film onto a substrate and then exposing the fluorinated silicate glass film to electron beam radiation. The electron beam exposing step is conducted by overall exposing the dielectric layer with a wide, large beam of electron beam radiation from a large-area electron beam source.
