    Abstract: A system and a method for passivating a surface of a semiconductor. The method includes providing the surface of the semiconductor to a reaction chamber of a reactor, exposing the surface of the semiconductor to a gas-phase metal containing precursor in the reaction chamber and exposing the surface of the semiconductor to a gas-phase chalcogenide containing precursor. The methods also include passivating the surface of the semiconductor using the gas-phase metal containing precursor and the gas-phase chalcogenide containing precursor to form a passivated surface. The system for passivating a surface of a semiconductor may include a reactor, a metal containing precursor source fluidly coupled to the reactor, and a chalcogenide containing precursor source fluidly couple to the reactor, wherein the metal containing precursor source provides a gas-phase metal containing precursor to a reaction chamber of the reactor, and wherein the chalcogenide containing precursor source provides a gas-phase chalcogenide containing precursor to a reaction chamber of the reactor.

    Abstract: In some aspects, methods of forming a metal chalcogenide thin film are provided. According to some methods, a metal chalcogenide thin film is deposited on a substrate in a reaction space in a cyclical deposition process where at least one cycle includes alternately and sequentially contacting the substrate with a first vapor-phase metal reactant and a second vapor-phase chalcogen reactant. In some aspects, methods of forming three-dimensional structure on a substrate surface are provided. In some embodiments, the method includes forming a metal chalcogenide dielectric layer between a substrate and a conductive layer. In some embodiments the method includes forming an MIS-type contact structure including a metal chalcogenide dielectric layer.

    Abstract: Methods and systems for depositing vanadium and/or indium layers onto a surface of a substrate and structures and devices formed using the methods are disclosed. 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.
