    摘要: The current disclosure relates to methods of depositing molybdenum on a substrate. The disclosure further relates to a molybdenum layer, to a structure and to a device comprising a molybdenum layer. In the method, molybdenum is deposited on a substrate by a cyclical deposition process, and the method comprises providing a substrate in a reaction chamber, providing a molybdenum precursor to the reaction chamber in a vapor phase and providing a reactant to the reaction chamber in a vapor phase to form molybdenum on the substrate. The molybdenum precursor comprises a molybdenum atom and a hydrocarbon ligand, and the reactant comprises a hydrocarbon comprising two or more halogen atoms, and at least two halogen atoms are attached to different carbon atoms.

    摘要: Systems and methods are described for depositing a TiN liner layer and a cobalt seed layer on a semiconductor wafer in a cobalt metallization process. In some embodiments the wafer is cooled after deposition of the TiN liner layer and/or the cobalt seed layer. In some embodiments the TiN liner layer and cobalt seed layer are deposited in process modules that are part of a semiconductor processing apparatus that also includes one or more modules for cooling the substrate. In some embodiments the cobalt seed layer may comprise a mixture of TiN and cobalt, a nanolaminate of TiN and cobalt layers or a graded TiN/Co layer.
