摘要:
A method of preparing components for use in a vacuum chamber of a lithographic apparatus is disclosed. The method includes coating the component with a non-metallic material. The method may further include treating the coating so as to harden the coating. Preferably, the coating material is a hydrogen silsesquioxane (HSQ), which may be applied via spraying, brushing, or spinning and can be treated by heating or by irradiation with an electron beam. The resulting components strongly reduce outgassing of water and hydrocarbons when subjected to a vacuum environment.
