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: The disclosure relates to methods of forming organic polymers comprising polyimide and layers comprising the same and to methods of reducing polyamic acid content of an organic polymer. The embodiments of the disclosure further relate to methods of fabricating semiconductor devices, to selectively depositing a material on a surface of a semiconductor substrate and to semiconductor processing assemblies. The methods are characterized by contacting a polyimide-containing material, such as a layer, with a modifying agent that increases the proportion of polyimide in the organic polymer material.

Abstract: A multiple-layer method for forming material within a gap on a surface of a substrate is disclosed. An exemplary method includes forming a layer of first material overlying the substrate and forming a layer of second (e.g., initially flowable) material within a region of the first material to thereby at least partially fill the gap with material in a seamless and/or void less manner.

An exemplary method includes using a cyclical deposition process, depositing a vanadium and/or indium layer onto the surface of the substrate. The cyclical deposition process can include providing a vanadium and/or indium precursor to the reaction chamber and separately providing a reactant to the reaction chamber. The cyclical deposition process may desirably be a thermal cyclical deposition process. Exemplary structures can include field effect transistor structures, such as gate all around structures. The vanadium and/or indium layers can be used, for example, as barrier layers or liners, as work function layers, as dipole shifter layers, or the like.
