Abstract:The effects of Al ion implantation on the adhesion of Al films to SiO2 substrates were investigated. The thickness of the Al films was about 100 nm. 70 keV Al ion implantation was performed with doses of 5×1015 and 5×1016 Al+/cm2. The adhesion was measured by scratch test. It was found that the film adhesion could be improved by more than ten times after implantation. The composition depth profiles of Auger electron spectroscopy showed that implantation results in the formation of Al2O3 at the interface and in… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
