Abstract:In this work, silicon-on-insulator wafers fabricated by the separation-byimplantation-of-oxygen method were modified by Si ion implantation to improve their total-dose radiation hardness. The chemical bonds of Si in the buried oxide layer were investigated using x-ray photoelectron spectroscopy. The results of Si 2p were presented to demonstrate the mechanism of radiation hardness with the formation of Si nanocrystals by ion implantation with the post anneal process. The pseudo-MOS method was used to test the … 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.
