Abstract

Abstract A process for forming a deposited film comprises introducing into a film forming space housing a substrate therein an active species (A) formed by decomposition of a compound containing germanium and a halogen and an active species (B) formed from a chemical substance for film formation which is reactive with said active species (A) separately form each other, and then allowing both the species to react with each other thereby to form a deposited film on the substrate.
