Abstract:The introduction and use of ultra low-k dielectric materials in an attempt to achieve better die performance brought new challenges to the wafer singulation / dicing process. Ultra low-k dielectric materials can easily get damaged during conventional blade dicing due to their brittleness. Thus, there is a need to investigate alternative or more advanced dicing techniques that can deliver successful dicing processes without inducing stress or damage. Apart from looking at the compatibility of the different dici… 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.
