Embodiments of the present invention generally relate to an apparatus and method of integration of titanium nitride layers. One embodiment (10, 20, 30) includes providing one or more cycles of a first set of compounds, (313) providing one or more cycles of a second set of compounds, and providing one or more cycles of a third set of compounds. One cycle of the first set of compounds includes introducing a titanium precursor and a reductant. One cycle of the second set of compounds (315) includes introducing the titanium precursor and a silicon precursor. One cycle of the third set of compounds includes introducing the titanium precursor and a nitrogen precursor. Another embodiment includes depositing a titanium layer utilizing titanium halide. Then, a passivation layer is deposited over the titanium layer utilizing titanium halide. The passivation layer may comprise titanium nitride, titanium silicon nitride, and combinations thereof. Then, a titanium nitride layer is deposited over the passivation layer utilizing titanium halide. |
