摘要： Embodiments of the invention relate to methods for depositing a metal silicon nitride layer on a substrate during an atomic layer deposition (ALD) process. In one embodiment, the method provides positioning a substrate within a process chamber containing a centralized expanding channel that conically tapers towards and substantially covers the substrate, flowing a process gas into the centralized expanding channel to form a circular flow pattern, exposing the substrate to the process gas having the circular flow pattern, and exposing the substrate sequentially to chemical precursors during an ALD process to form a metal silicon nitride material. In one example, the ALD process provides sequentially pulsing a metal precursor, a nitrogen precursor, and a silicon precursor into the process gas having the circular flow pattern. The metal silicon nitride material may contain tantalum or titanium. In other examples, the process gas or the substrate may be exposed to a plasma.

摘要： A system for processing a substrate is provided which includes at least one atomic layer deposition (ALD) chamber for depositing a barrier layer containing tantalum and at least one physical vapor deposition (PVD) metal seed chamber for depositing a metal seed layer on the barrier layer. The at least one ALD chamber may be in fluid communication with a first precursor source providing a tantalum-containing compound and a second precursor source. In one example, the tantalum-containing compound is an organometallic tantalum precursor, such as PDMAT. In another example, the second precursor source contains a nitrogen precursor, such as ammonia. The PDMAT may have a chlorine concentration of about 100 ppm or less, preferably, about 30 ppm or less, and more preferably, about 5 ppm or less. In some examples, the PVD metal seed chamber is used to deposit a copper-containing metal seed layer.
