Abstract: Embodiments of the present disclosure generally relate to an apparatus and a method for cleaning a processing chamber. In one embodiment, a substrate support cover includes a bulk member coated with a fluoride coating. The substrate support cover is placed on a substrate support disposed in the processing chamber during a cleaning process. The fluoride coating does not react with the cleaning species. The substrate support cover protects the substrate support from reacting with the cleaning species, leading to reduced condensation formed on chamber components, which in turn leads to reduced contamination of the substrate in subsequent processes.

Abstract: The present disclosure is related to the field of polymer materials, and, in particular, to a method for synthesizing a bio-based polyamide. More specifically, the disclosure provides a method for synthesizing a block copolymer consisting of a hard segment of a polyamide prepared via solid state polycondensation and a soft segment of a polyether polyol. Due to a reaction of itaconic acid, which contains a carbon-carbon double bond, with hexamethylenediamine, the bio-based polyamide is greatly different from conventional linear polyamides and exhibits a lower glass transition temperature and excellent mechanical properties. Unlike conventional processes for preparing modified polyamides, the bio-based polyamide is synthesized, according to the method, through chain extension of a polyamide with an excess amount of a diisocyanate based on amine value of the polyamide and then crosslinking of the resulting product with a polyether polyol by using glycerol as a crosslinking agent.
