摘要:
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.
