Deposition methods and apparatus for conditioning a process kit to increase process kit lifetime are described. A nitride film formed on a process kit is exposed to conditioning process comprising nitrogen and hydrogen radicals to condition the nitride film to decrease particulate contamination from the process kit.

Conditioning treatment for ALD productivity

Described are methods for doping barrier layers such as tantalum (Ta), tantalum nitride (TaN), tantalum carbide (TaC), niobium (Nb), niobium nitride (NbN), manganese (Mn), manganese nitride (MnN), titanium (Ti), titanium nitride (TiN), molybdenum (Mo), and molybdenum nitride (MoN), and the like. Dopants may include one or more of one or more of ruthenium (Ru), manganese (Mn), niobium (Nb), cobalt (Co), vanadium (V), copper (Cu), aluminum (Al), carbon (C), oxygen (O), silicon (Si), molybdenum (Mo), and the like. The doped barrier layer provides improved adhesion at a thickness of less than about 15 &#x212b;.
