Abstract

A metal thin film is deposited on predetermined portions of an underlayer of a substrate by a chemical deposition method with good selectivity, good reproducibility and high deposition rate by preventing hydrogen atoms from the adhesion to portions of the substrate not to be deposited with a metal using a special means for heating only the substrate or a special gas flow controlling means.
