Abstract: Methods and systems for depositing vanadium nitride layers onto a surface of the substrate and structures and devices formed using the methods are disclosed. An exemplary method includes using a cyclical deposition process, depositing a vanadium nitride layer onto a surface of the substrate. The cyclical deposition process can include providing a vanadium halide precursor to the reaction chamber and separately providing a nitrogen reactant to the reaction chamber. The cyclical deposition process may desirably be a thermal cyclical deposition process.

Abstract: Molybdenum (Mo) metal-on-metal (MoM) deposition methods for providing true bottom-up fill in vias and/or other gap features in device structures. These device structures contain metal at the bottom surface and have dielectric sidewalls. The deposition process provides molybdenum growth only, in some cases, on the metal film/layer to provide a selective process that can be called a metal-on-metal (MoM) process. The Mo MoM deposition process described herein are not limited to thin films (e.g., films less than 50 Å) and can be used to deposit thicker films (e.g., greater than 50 Å in some cases and greater than 200 Å in other useful cases) on metal surfaces while no, or substantially no, deposition is found on dielectric surfaces.

Abstract: Methods for forming hafnium oxide within a three-dimensional structure, such as in a high aspect ratio hole, are provided. The methods may include depositing a first hafnium-containing material, such as hafnium nitride or hafnium carbide, in a three-dimensional structure and subsequently converting the first hafnium-containing material to a second hafnium-containing material comprising hafnium oxide by exposing the first hafnium-containing material to an oxygen reactant. The volume of the second hafnium-containing material may be greater than that of the first hafnium-containing material. Voids or seams formed during the deposition of the first hafnium-containing material in the three-dimensional structure may be filled by the expanded material after exposing the first hafnium-containing material to the oxygen reactant. Thus, the three-dimensional structure, such as a high aspect ratio hole, can be filled with hafnium oxide substantially free of voids or seams.

Abstract: Methods of forming molybdenum silicide are disclosed. Exemplary methods can include selectively forming molybdenum silicide on a first surface relative to a second surface. Additionally or alternatively, exemplary methods can include a cleaning step prior to forming the molybdenum silicide.

Abstract: 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.
