Abstract:
1. A method of manufacturing a semiconductor device, performed to a substrate including: an interlayer insulation film having a recess formed therein; and a lower metal wiring, in a lower layer, whose main component is a first metal, the lower metal wiring being exposed to a bottom surface of the recess; the method comprising: forming a barrier film, which is a compound of a second metal and is configured to restrain diffusion of the first metal, on an exposed surface of the interlayer insulation film, by supplying a steam of an organic metal compound containing the second metal so as to react the organic metal compound containing the second metal with a part of components of the interlayer insulation film; and then, embedding a metal wiring whose main component is the first metal in the recess.
