    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 provide chemical precursor ampoules that may be used during vapor deposition processes. In one embodiment, an apparatus for generating a chemical precursor gas used in a vapor deposition processing system is provided which includes a canister having a sidewall, a top, and a bottom forming an interior volume and a solid precursor material at least partially contained within a lower region of the interior volume. The apparatus further contains an inlet port and an outlet port in fluid communication with the interior volume and an inlet tube connected to the inlet port and positioned to direct a carrier gas towards the sidewall and away form the outlet port. In one example, the solid precursor contains pentakis(dimethylamido) tantalum (PDMAT). In another example, the apparatus contains a plurality of baffles that form an extended mean flow path between the inlet port and the outlet port.
