A process for forming a deposition film on a substrate comprises introducing separately a precursor or activated species formed in a decomposition space (B) and activated species formed in a decomposition space (C), into the deposition space wherein the film is formed on the substrate.

Process for forming deposition film

A deposition film is formed on a substrate in a deposition space (A) by the chemical reaction between a gaseous precursor of a higher silicon halide or a higher halosilane formed in a decomposition space (B) and a separately-introduced gaseous, activated species of hydrogen, silane or a halosilane formed in a decomposition space (C).
