摘要: A method and apparatus for depositing a tantalum nitride barrier layer is provided for use in an integrated processing tool. The tantalum nitride is deposited by atomic layer deposition. The tantalum nitride is removed from the bottom of features in dielectric layers to reveal the conductive material under the deposited tantalum nitride. Optionally, a tantalum layer may be deposited by physical vapor deposition after the tantalum nitride deposition. Optionally, the tantalum nitride deposition and the tantalum deposition may occur in the same processing chamber.

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: A method for depositing a refractory metal nitride barrier layer having a thickness of about 20 angstroms or less is provided. In one aspect, the refractory metal nitride layer is formed by introducing a pulse of a metal-containing compound followed by a pulse of a nitrogen-containing compound. The refractory metal nitride barrier layer provides adequate barrier properties and allows the grain growth of the first metal layer to continue across the barrier layer into the second metal layer thereby enhancing the electrical performance of the interconnect.
