Abstract:The transition to semiconductor design nodes below 100 nm will create high demands on metrology solutions for the detection and chemical characterization of defects and particles throughout all processing steps. The compositional analysis of particles with sizes below about 20 nm is one particular challenge. We describe progress in the development of a highly charged ion based secondary ion mass spectrometry (HCI-SIMS) schemes aimed at addressing this challenge. Using ions like Xe 48+ as projectiles increases … 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.
