    Abstract: Methods and apparatus for processing a substrate are provided. For example, a method includes sputtering a material from a target in a PVD chamber to form a material layer on a layer comprising a feature of the substrate, the feature having an opening width defined by a first sidewall and a second sidewall, the material layer having a greater lateral thickness at the top surface of the layer than a thickness on the first sidewall or the second sidewall within the feature, depositing additional material on the layer by biasing the layer with an RF bias at a low power, etching the material layer from the layer by biasing the layer with an RF bias at a high-power, and repeatedly alternating between the low power and the high-power at a predetermined frequency.

    Abstract: Embodiments disclosed herein generally relate to methods of depositing a plurality of layers. A doped copper seed layer is deposited in a plurality of feature definitions in a device structure. A first copper seed layer is deposited and then the first copper seed layer is doped to form a doped copper seed layer, or a doped copper seed layer is deposited directly. The doped copper seed layer leads to increased flowability, reducing poor step coverage, overhang, and voids in the copper layer.

    Abstract: Embodiments of the present disclosure generally relate to a low temperature non-plasma containing preclean process to selectively remove contaminants from the surface of a substrate, such as halogen containing and/or metal oxide containing contaminants. The non-plasma containing precleaning process is performed at a low temperature by use of a microwave source that is configured to provide microwave energy to the processing gases disposed within a processing chamber. The non-plasma low temperature preclean process is effective in reducing halogen containing residues, such as fluorine and chlorine containing residues formed on a surface of a substrate.

    Abstract: Methods open etch stop layers in an integrated environment along with metallization processes. In some embodiments, a method for opening an etch stop layer (ESL) prior to metallization may include etching the ESL with an anisotropic process using direct plasma to form helium ions that are configured to roughen the ESL for a first duration of approximately 10 seconds to approximately 30 seconds, forming aluminum fluoride on the ESL using remote plasma and nitrogen trifluoride gas for a second duration of approximately 10 seconds to approximately 30 seconds, and exposing the ESL to a gas mixture of boron trichloride, trimethylaluminum, and/or dimethylaluminum chloride at a temperature of approximately 100 degrees Celsius to approximately 350 degrees Celsius to remove aluminum fluoride from the ESL and a portion of a material of the ESL for a third duration of approximately 30 seconds to approximately 60 seconds.

    Abstract: In some embodiments, an integrated tool for opening an etch stop layer and performing metallization comprises a first chamber with a remote plasma source, a direct plasma source, and a thermal source configured to open the etch stop layer on a substrate, a second chamber of the integrated tool with dry etch processing configured to pre-clean surfaces exposed by opening the etch stop layer, a third chamber of the integrated tool configured to deposit a barrier layer on the substrate, a fourth chamber of the integrated tool configured to deposit a liner layer on the substrate, and at least one fifth chamber of the integrated tool configured to deposit metallization material on the substrate. The integrated tool may also include a vacuum transfer chamber.
