Abstract: Disclosed are methods and systems for depositing layers comprising a transition metal and a group 13 element. The layers are formed onto a surface of a substrate. The deposition process may be a cyclical deposition process. Exemplary structures in which the layers may be incorporated include field effect transistors, VNAND cells, metal-insulator-metal (MIM) structures, and DRAM capacitors.

Abstract: The current disclosure relates to the manufacture of semiconductor devices, specifically to methods of forming vanadium metal on a substrate. The methods comprise providing a substrate in a reaction chamber, providing a vanadium precursor to the reaction chamber in a vapor phase and providing a reducing agent to the reaction chamber in a vapor phase to form vanadium metal on the substrate. The disclosure further relates to structures and devices formed by the methods, as well as to a deposition assembly.

Abstract: Methods and systems for depositing a layer, comprising one or more of vanadium boride and vanadium phosphide, onto a surface of a substrate and structures and devices formed using the methods are disclosed. An exemplary method includes using a deposition process. The deposition process can include providing a vanadium precursor to the reaction chamber and separately providing a reactant to the reaction chamber. Exemplary structures can include field effect transistor structures, such as gate all around structures. The layer comprising one or more of vanadium boride and vanadium phosphide can be used, for example, as barrier layers or liners, as work function layers, as dipole shifter layers, or the like.
