Abstract

A vacuum-UV F₂ laser of 157 nm wavelength induced strong oxidation of Fe thin film surface to show the chemical resistance to pseudo seawater and HNO₃ aqueous solution for selective metallization on silica glass substrate. The strong oxidation reactions on the surface and in the depth direction were confirmed by X-ray photoelectron spectroscopy. The corrosion resistance of the F₂ laser irradiated samples was also supported by an electrochemical test. A fine pattern of the F₂ laser irradiated Fe thin film was successfully formed after the HNO₃ chemical etching.
