A semiconductor substrate is loaded into a reaction chamber to form a tungsten layer. A source gas including tungsten (W) is introduced into the reaction chamber to grow a crystal nucleus of the tungsten on the semiconductor substrate. A reduction gas containing boron (B) is introduced into the reaction chamber to form a tungsten layer on the semiconductor substrate by actions of the source gas and the reduction gas. A hydrogen (H2) gas is introduced into the reaction chamber to remove the boron (B) remaining in the tungsten layer.

A method for fabricating an interconnection in a semiconductor device includes forming a hydrogenated tungsten nucleation layer on a semiconductor substrate, and forming a bulk tungsten layer on the tungsten nucleation layer. Boron ions react with a hydrogen gas supplied together with a diborane gas to be restored to a diborane again, thereby preventing a boron layer from being formed on an interface of the tungsten nucleation layer.
