ABSTRACT:
An improved reaction chamber cleaning process is provided for removing water residues that makes use of noble-gas plasma reactions. The method is easy applicable and may be combined with standard cleaning procedure. A noble-gas plasma (e.g. He) that emits high energy EUV photons (E>20 eV) which is able to destruct water molecules to form electronically excited oxygen atoms is used to remove the adsorbed water.
