    Abstract: Methods of selectively etching metals and metal nitrides from the surface of a substrate are described. The etch selectively removes metals and metal nitrides relative to silicon-containing layers such as silicon, polysilicon, silicon oxide, silicon germanium, silicon carbide, silicon carbon nitride and/or silicon nitride. The etch removes material in a conformal manner by including an oxidation operation which creates a thin uniform metal oxide. The thin uniform metal oxide is then removed by exposing the metal oxide to a metal-halogen precursor in a substrate processing region. The metal oxide may be removed to completion and the etch may stop once the uniform metal oxide layer is removed. Etches described herein may be used to uniformly trim back material on high aspect ratio features which ordinarily show higher etch rates near the opening of a gap compared to deep within the gap.

    Abstract: Embodiments include a method of processing a hardmask that includes forming an alloyed carbon hardmask over an underlying layer. In an embodiment, the alloyed carbon hardmask is alloyed with metallic-carbon fillers. The embodiment further includes patterning the alloyed carbon hardmask and transferring the pattern of the alloyed carbon hardmask into the underlying layer. According to an embodiment, the method may further include removing the metallic component of the metallic-carbon fillers from the alloyed carbon hardmask to form a porous carbon hardmask. Thereafter, the porous hardmask may be removed. In an embodiment, the metallic component of the metallic-carbon fillers may include flowing a processing gas into a chamber that volatizes the metallic component of the metallic-carbon fillers.

    Abstract: Described herein is a method of depositing a conformal, optically transparent coating onto a surface of one or more internal components that are enclosed within an assembled device using a non-line-of-sight deposition process without altering a structure of the assembled device or impacting functionality of the assembled device. Also described is an assembled device including one or more internal components enclosed within the assembled device and a coating deposited onto a surface of the internal components enclosed within the assembled device, where the coating is a conformal, optically transparent coating that is resistant to corrosion by at least one of fluorine-, chlorine-, sulfur-, hydrogen-, bromine-, or nitrogen-based acids and that does not negatively impact functionality of the internal components.
