Abstract

A method of chemically depositing a copper film in which a bromine or iodine-containing catalyst component is employed to enhance the deposition rate. The present invention is characterized in that the catalyst component floats on the film surface during the film formation. Accordingly, a film deposition having superior step coverage and high deposition rate is obtained.
