Abstract: Methods and related systems for filling a gap feature comprised in a substrate are disclosed. The methods comprise a step of providing a substrate comprising one or more gap features into a reaction chamber. The one or more gap features comprise an upper part comprising an upper surface and a lower part comprising a lower surface. The methods further comprise a step of subjecting the substrate to a plasma treatment. Thus, the upper surface is inhibited while leaving the lower surface substantially unaffected. Then, the methods comprise a step of selectively depositing a silicon-containing material on the lower surface.

Abstract: The current disclosure relates to methods of selectively etching material from a first surface of a substrate relative to a second surface of the substrate. The method includes providing the substrate having a first surface comprising an etchable material, and a second surface comprising a non-etchable material in a reaction chamber, providing hydrogen-containing plasma into the reaction chamber to reduce the etchable material to a predetermined depth; and providing remotely-generated reactive halogen species and hydrogen into the reaction chamber to selectively etch the reduced etchable material. The disclosure further relates to methods of selectively etching at least two different etchable materials simultaneously from a surface of a substrate relative to a non-etchable material on the same substrate, to methods of simultaneous differential etching of three or more etchable materials on a substrate, as well as to assemblies for processing semiconductor substrates.

Abstract: An etching process is provided that includes a pre-clean process to remove a surface oxide of a dielectric material. The removal of the oxide can be executed through a thermal reaction and/or plasma process before the etch process. In some embodiments, the removal of the oxide increases etch process control and reproducibility and can improve the selectivity versus oxides.
