Abstract: A method for improving source/drain performance through conformal solid state doping and its resulting device are disclosed. Specifically, the doping takes place through an atomic layer deposition of a dopant layer. Embodiments of the invention may allow for an increased doping layer, improved conformality, and reduced defect formation, in comparison to alternate doping methods, such as ion implantation or epitaxial doping.

Abstract: A method for depositing one or more layers on a substrate is disclosed. The method may comprise providing a substrate, etching a native oxide from a surface of the substrate responsive to exposure to an etchant, contacting an etched surface of the substrate with an oxidizing agent oxidizing a first layer of the substrate responsive to contact with the oxidizing agent and depositing a second layer on the first layer.

Abstract: Methods for selective deposition are provided. Material is selectively deposited on a first surface of a substrate relative to a second surface of a different material composition. An inhibitor, such as a polyimide layer, is selectively formed from vapor phase reactants on the first surface relative to the second surface. A layer of interest is selectively deposited from vapor phase reactants on the second surface relative to the first surface. The first surface can be metallic while the second surface is dielectric. Accordingly, material, such as a dielectric transition metal oxides and nitrides, can be selectively deposited on metallic surfaces relative dielectric surfaces using techniques described herein.

Abstract: Methods of forming indium gallium zinc oxide (IGZO) films by vapor deposition are provided. The IGZO films may, for example, serve as a channel layer in a transistor device. In some embodiments atomic layer deposition processes for depositing IGZO films comprise an IGZO deposition cycle comprising alternately and sequentially contacting a substrate in a reaction space with a vapor phase indium precursor, a vapor phase gallium precursor, a vapor phase zinc precursor and an oxygen reactant. In some embodiments the ALD deposition cycle additionally comprises contacting the substrate with an additional reactant comprising one or more of NH3, N2O, NO2 and H2O2.
