    摘要: A method of forming a conductive plug for an integrated circuit device may include forming an insulating layer on an integrated circuit substrate with the insulating layer having a surface opposite the substrate and a recess therein. A titanium (Ti) layer may be formed on sidewalls of the recess and on the surface of the insulating layer opposite the substrate. After forming the titanium (Ti) layer, a reaction reducing layer may be formed on portions of the titanium layer on the surface of the insulating layer opposite the substrate by at least one of ionized physical vapour deposition (iPVD) and/or nitriding a portion of the titanium layer, and the reaction reducing layer may include a material other than titanium. After forming the reaction reducing layer, a TiN layer may be formed on the reaction reducing layer and on sidewalls of the recess in the insulating layer using metal organic chemical vapour deposition (MOCVD). After forming the TiN layer, a conductive plug may be formed on the TiN layer in the recess in the insulating layer.

    摘要: A method of forming a tungsten silicide layer and a related method of fabricating a semiconductor element. The method of forming the tungsten silicide layer includes forming a pre-coating layer within a CVD process chamber by injecting a tungsten source gas (A) and a silicon source gas (B) at a flow ratio (A/B) of 1/50 or less, and thereafter loading a semiconductor substrate into the CVD process chamber in which the precoating layer is formed, and injecting additional tungsten source gas and silicon source gas to form the tungsten silicide layer on the semiconductor substrate.

    摘要: Embodiments of the invention provide a method for removing hydrogen gas from a chamber and a method for performing a semiconductor device fabrication sub-process and removing hydrogen gas from a chamber. The method for removing hydrogen gas from a chamber comprises removing a substrate from a chamber, wherein residual hydrogen gas is disposed in the chamber, injecting oxygen gas or ozone gas into the chamber, producing plasma in the chamber, and removing OH radicals from the chamber.
