Abstract:
1. A semiconductor device manufacturing method comprising: modifying a surface of a burying recess formed in a dielectric film by supplying dimethylethylenediamine in a liquid or a gaseous state to the dielectric film formed on a substrate and containing silicon, carbon, hydrogen and oxygen, a bottom portion of the burying recess being exposed with a lower conductive layer, wherein the dimethylethylenediamine is adsorbed onto the surface of the dielectric film to thereby enhance a nucleation and a growth of Ru; directly forming a barrier film formed of a Ru film on the modified surface of the recess, wherein the Ru film is formed by using chemical vapor deposition Ru3(CO)12 gas and CO gas; and burying copper forming a conductive path in the recess.
