PROBLEM TO BE SOLVED: To provide a method for easily depositing a metallic film made into a seed layer upon burying metal, particularly copper into a trench in a substrate as an insulator by a plating process, further playing a roll as a barrier layer for preventing the migration of metal atoms to an insulation film and also having excellent adhesion with the insulator. SOLUTION: In the method, a metallic compound on a substrate in which a film of at least one metallic compound selected from a cobalt compound, a ruthenium compound and a tungsten compound is deposited, is sublimed, the sublimed gas is fed to a substrate for depositing a metallic film, so as to be decomposed, thus the metallic film is deposited on the surface of the substrate.

SOLUTION: A cyclic olefin-based addition copolymer is obtained by addition polymerization of a cyclic olefin compound having a side chain substituent of a cyclic structure such as endo-tricyclo[4.3.0.1 2,5 ]deca-3, 7-diene, endo-tricyclo[4.3.0.1 2,5 ]dec-3-ene or the like or hydrogenation after the polymerization, or copolymerization of the compound with another cyclic olefin compound such as bicyclo[2.2.1]hept-2-ene or the like, a cyclic olefin compound having a hydrolyzable silyl group or hydrogenation after the copolymerization. A composition for crosslinking is obtained by adding a specific crosslinking agent to the addition copolymer. A crosslinked product is obtained by crosslinking the composition. The optical materials comprise the copolymer, the composition or the crosslinked product. The method for producing the copolymer is to carry out the addition polymerization by using a specific nickel catalyst. COPYRIGHT: (C)2004,JPO
