    摘要: In one embodiment, a method for forming a titanium nitride barrier material on a substrate is provided which includes depositing a titanium nitride layer on the substrate by a metal-organic chemical vapor deposition (MOCVD) process, and thereafter, densifying the titanium nitride layer by exposing the substrate to a plasma process. In one example, the MOCVD process and the densifying plasma process is repeated to form a barrier stack by depositing a second titanium nitride layer on the first titanium nitride layer. In another example, a third titanium nitride layer is deposited on the second titanium nitride layer. Subsequently, the method provides depositing a conductive material on the substrate and exposing the substrate to a annealing process. In one example, each titanium nitride layer may have a thickness of about 15 Å and the titanium nitride barrier stack may have a copper diffusion potential of less than about 5×1010 atoms/cm2.

    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.

    摘要: Embodiments of the invention described herein generally provide methods for forming cobalt silicide layers and metallic cobalt layers by using various deposition processes and annealing processes. In one embodiment, a method for forming a metallic silicide containing material on a substrate is provided which includes forming a metallic silicide material over a silicon-containing surface during a vapor deposition process by sequentially depositing a plurality of metallic silicide layers and silyl layers on the substrate, depositing a metallic capping layer over the metallic silicide material, heating the substrate during an annealing process, and depositing a metallic contact material over the barrier material. In one example, the metallic silicide layers and the metallic capping layer both contain cobalt. The cobalt silicide material may contain a silicon/cobalt atomic ratio of about 1.9 or greater, such as greater than about 2.0, or about 2.2 or greater.
