Process for treatment of thin films based upon metallic oxide or nitride

摘要

A treatment process for the purpose of improving the chemical and/or physical durability of film containing one or more metallic oxides, nitrides, oxynitrides or oxycarbides deposited on a transparent substrate by a cathodic sputtering technique, notably assisted by a magnetic field and preferably reactive in the presence of oxygen. Said process consists of subjecting the film to a low energy ion beam.
