    Abstract: Methods for surface interface engineering in semiconductor fabrication are provided herein. In some embodiments, a method of processing a substrate disposed atop a substrate support in a processing volume of a processing chamber includes: generating an ion species from an inductively coupled plasma formed within the processing volume of the processing chamber from a first process gas; exposing a first layer of the substrate to the ion species to form an ammonium fluoride (NH 4 F) film atop the first layer, wherein the first layer comprises silicon oxide; and heating the substrate to a second temperature at which the ammonium fluoride film reacts with the first layer to selectively etch the silicon oxide.

    Abstract: Implementations of the present disclosure generally relate to methods and apparatuses for epitaxial deposition on substrate surfaces. More particularly, implementations of the present disclosure generally relate to methods and apparatuses for surface preparation prior to epitaxial deposition. In one implementation, a method of processing a substrate is provided. The method comprises etching a surface of a silicon-containing substrate by use of a plasma etch process to form an etched surface of the silicon-containing substrate and forming an epitaxial layer on the etched surface of the silicon-containing substrate. The plasma etch process comprises flowing an etchant gas mixture comprising a fluorine-containing precursor and a hydrogen-containing precursor into a substrate-processing region of a first processing chamber and forming a plasma from the etchant gas mixture flowed into the substrate-processing region.

More particularly, implementations of the present disclosure generally relate to methods and apparatuses for surface preparation prior to epitaxial deposition. In one implementation, a method of processing a substrate is provided. The method comprises etching a surface of a silicon-containing substrate by use of a plasma etch process, where at least one etching process gas comprising chlorine gas and an inert gas is used during the plasma etch process and forming an epitaxial layer on the surface of the silicon-containing substrate.
