摘要: A barrier layer including a titanium film is formed at a low temperature, and a TiSix film is self-conformably formed at the interface between the titanium film and the base. In forming the TiSix film 507, the following steps are repeated without introducing argon gas: a first step of introducing a titanium compound gas into the processing chamber to adsorb the titanium compound gas onto the silicon surface of a silicon substrate 502; a second step of stopping introduction of the titanium compound gas into the processing chamber and removing the titanium compound gas remaining in the processing chamber; and a third step of generating plasma in the processing chamber while introducing hydrogen gas into the processing chamber to reduce the titanium compound gas adsorbed on the silicon surface and react it with the silicon in the silicon surface to form the TiSix film 507.
