    摘要: 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 including an optical encoder 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 an optical encoder, where one or more internal components enclosed within the optical encoder and a coating deposited onto a surface of the internal components, 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.

    摘要: 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.
