Abstract:We developed a novel copper-bondable silver paste for the pressureless bonding of large-area chip on bare copper substrate. This paste includes silver nanoparticles, silver submicron-sized flakes, and organics. The finally densification, which is controlled by grain boundary and lattice diffusions, was developed by the formation of robust solid necks among the nanoparticles and flakes. The sintered silver joint showed high shear strength, low porosity, low thermal impedance, and barely any void. This silver pa… 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.
